KNOWN ISSUES:

- Pinephone Pro:
  - imx258 capture doesn't work after suspend/resume cycle (test)

- Pinephone:
  - You may experience p-boot display pipeline handover failures with the
    new HDMI HPD fix since (2021-10-26) if you have drivers compiled in such
    a way that parts of the sunxi DRM stack have to re-probe on boot.
    One way to workaround this is to compile everything needed for anx7688
    and display pipeline as built-in drivers.
  - Bluetooth is never powered off. Only way to power it off is to unload
    the bluetooth driver module. (rfkill or bluetoothctl power off do not
    work)

2022-11-01:
- rebased on v6.1-rc3
- add pinephone keyboard power manager driver
  - this driver manages charging cycle of both batteries and provides
    LED triggers, uevents and combined state in debugfs/kbpwr/state usable
    for summary capacity/discharge rate reporting
  - the driver optimizes for the highest power efficiency (power is used
    more directly without needless recharging of phone's battery from the
    keyboard battery)
  - the driver also performs calibration of kb battery internal resistance
    to improve reliability of capacity reporting of keyboard battery
  - the driver optionally provides emergency shutdown when both batteries
    are almost discharged
- make various PMIC drivers report battery capacity in uWh to userspace
  to make calculations for total capacity of multi-battery setup with
  different sized batteries more meaningful
- move to mainlined pinephone-keyboard driver
- ported sun6i-csi patches over to the 6.1 (base driver was changed quite
  a lot in rc2, so multicamera support needed to be rewritten from scratch)
- fixed pinephone keyboard current reporting (with large currents, the
  keyboard would sometimes report incorrect negative values due to integer
  overflow)
- renamed ppp selfie camera sensor subdevice name to be mainline compatible
- ppkb: allowed to disable special handling of FN layer via module parameter
  (to make it possible to use Fn key as another modifier key in xkb)
- hopefully final fix for quartz64-a pcie register/address ranges map
- added buffer support for af8133j magnetometer driver
- removed useless error messages
- sun4i-drm (pinephone) DRM driver fixes
  - rewritten patches that fix layer positioning and fixed additional bugs
    in the driver (reconfiguring planes while crtc was turned off led to
    corruption/stale framebuffer being scanned to the display)
- pinephone: fix power key getting stuck after resume, when pressed and
  released quickly enough (reported by Aren)

- rebase on v5.18
- added support for front and back camera for Pinephone Pro
- resolved clock frequency incompatibility between the sensor drivers
2022-05-21:
- rebase on v5.18-rc8
- stupid ass schematic for pinephone pro is completely confusing, which is one
  reason why world facing camera didn't work up to now. See for yourself:
  This https://megous.com/dl/tmp/39cbd011289c6818.png apparently means that
  IMX258 is connected to MIPI1_TX1/RX1 lol https://megous.com/dl/tmp/5f25b00ef0166252.png
  MIPI_RX0 is isp0 MIPI1_RX1 is isp1. Just by reading the camera sheet in the
  schematic, I happily assumed that naming signals MIPI_RX0, they actually really
  are MIPI_RX0, but alas. Anyway, I moved IMX258 sensor node in device tree
  to isp1, so that increases chances that users who have working connection
  to the sensor over I2C will have a working camera now. :) Please test and
  report back.
- some cleanup and patch re-ordering in ppp branches
- drop A64 idle states from DT (these should be auto-added by TF-A when supported;

My kernel's main integration branch is 'orange-pi-$VER' (this one).
No other branch is supposed to work alone. My defconfigs are tested
and work on the boards I support. Read the README.md for more info.

Only my branches based on the current mainline kernel branch are
maintained (those are usually the -rc# kernels!). You can find the
current mainline version here https://www.kernel.org/ (mainline: ...)

My prebuilt kernels can be found at https://xff.cz/kernels/ You can
use them to test that your board works, or just run them without
bothering with building everything yourself. I run them on all my
boards.

My website is https://xnux.eu and may contain useful advice.

Good luck!

    c416b5ba · x86/fred: Fix init_task thread stack pointer initialization · 
    Support for x86 Fast Return and Event Delivery (FRED):

FRED is a replacement for IDT event delivery on x86 and addresses most of
the technical nightmares which IDT exposes:

 1) Exception cause registers like CR2 need to be manually preserved in
    nested exception scenarios.

 2) Hardware interrupt stack switching is suboptimal for nested exceptions
    as the interrupt stack mechanism rewinds the stack on each entry which
    requires a massive effort in the low level entry of #NMI code to handle
    this.

 3) No hardware distinction between entry from kernel or from user which
    makes establishing kernel context more complex than it needs to be
    especially for unconditionally nestable exceptions like NMI.

 4) NMI nesting caused by IRET unconditionally reenabling NMIs, which is a
    problem when the perf NMI takes a fault when collecting a stack trace.

 5) Partial restore of ESP when returning to a 16-bit segment

 6) Limitation of the vector space which can cause vector exhaustion on
    large systems.

 7) Inability to differentiate NMI sources

FRED addresses these shortcomings by:

 1) An extended exception stack frame which the CPU uses to save exception
    cause registers. This ensures that the meta information for each
    exception is preserved on stack and avoids the extra complexity of
    preserving it in software.

 2) Hardware interrupt stack switching is non-rewinding if a nested
    exception uses the currently interrupt stack.

 3) The entry points for kernel and user context are separate and GS BASE
    handling which is required to establish kernel context for per CPU
    variable access is done in hardware.

 4) NMIs are now nesting protected. They are only reenabled on the return
    from NMI.

 5) FRED guarantees full restore of ESP

 6) FRED does not put a limitation on the vector space by design because it
    uses a central entry points for kernel and user space and the CPUstores
    the entry type (exception, trap, interrupt, syscall) on the entry stack
    along with the vector number. The entry code has to demultiplex this
    information, but this removes the vector space restriction.

    The first hardware implementations will still have the current
    restricted vector space because lifting this limitation requires
    further changes to the local APIC.

 7) FRED stores the vector number and meta information on stack which
    allows having more than one NMI vector in future hardware when the
    required local APIC changes are in place.

The series implements the initial FRED support by:

 - Reworking the existing entry and IDT handling infrastructure to
   accomodate for the alternative entry mechanism.

 - Expanding the stack frame to accomodate for the extra 16 bytes FRED
   requires to store context and meta information

 - Providing FRED specific C entry points for events which have information
   pushed to the extended stack frame, e.g. #PF and #DB.

 - Providing FRED specific C entry points for #NMI and #MCE

 - Implementing the FRED specific ASM entry points and the C code to
   demultiplex the events

 - Providing detection and initialization mechanisms and the necessary
   tweaks in context switching, GS BASE handling etc.

The FRED integration aims for maximum code reuse vs. the existing IDT
implementation to the extent possible and the deviation in hot paths like
context switching are handled with alternatives to minimalize the
impact. The low level entry and exit paths are seperate due to the extended
stack frame and the hardware based GS BASE swichting and therefore have no
impact on IDT based systems.

It has been extensively tested on existing systems and on the FRED
simulation and as of now there are know outstanding problems.

    f0551af0 · x86/topology: Ignore non-present APIC IDs in a present package · 
    Rework of APIC enumeration and topology evaluation:

The current implementation has a couple of shortcomings:

  - It fails to handle hybrid systems correctly.

  - The APIC registration code which handles CPU number assignents is in
    the middle of the APIC code and detached from the topology evaluation.

  - The various mechanisms which enumerate APICs, ACPI, MPPARSE and guest
    specific ones, tweak global variables as they see fit or in case of
    XENPV just hack around the generic mechanisms completely.

  - The CPUID topology evaluation code is sprinkled all over the vendor
    code and reevaluates global variables on every hotplug operation.

  - There is no way to analyze topology on the boot CPU before bringing up
    the APs. This causes problems for infrastructure like PERF which needs
    to size certain aspects upfront or could be simplified if that would be
    possible.

  - The APIC admission and CPU number association logic is incomprehensible
    and overly complex and needs to be kept around after boot instead of
    completing this right after the APIC enumeration.

This update addresses these shortcomings with the following changes:

  - Rework the CPUID evaluation code so it is common for all vendors and
    provides information about the APIC ID segments in a uniform way
    independent of the number of segments (Thread, Core, Module, ..., Die,
    Package) so that this information can be computed instead of rewriting
    global variables of dubious value over and over.

  - A few cleanups and simplifcations of the APIC, IO/APIC and related
    interfaces to prepare for the topology evaluation changes.

  - Seperation of the parser stages so the early evaluation which tries to
    find the APIC address can be seperately overridden from the late
    evaluation which enumerates and registers the local APIC as further
    preparation for sanitizing the topology evaluation.

  - A new registration and admission logic which

     - encapsulates the inner workings so that parsers and guest logic
       cannot longer fiddle in it

     - uses the APIC ID segments to build topology bitmaps at registration
       time

     - provides a sane admission logic

     - allows to detect the crash kernel case, where CPU0 does not run on
       the real BSP, automatically. This is required to prevent sending
       INIT/SIPI sequences to the real BSP which would reset the whole
       machine. This was so far handled by a tedious command line
       parameter, which does not even work in nested crash scenarios.

     - Associates CPU number after the enumeration completed and prevents
       the late registration of APICs, which was somehow tolerated before.

  - Converting all parsers and guest enumeration mechanisms over to the
    new interfaces.

    This allows to get rid of all global variable tweaking from the parsers
    and enumeration mechanisms and sanitizes the XEN[PV] handling so it can
    use CPUID evaluation for the first time.

  - Mopping up existing sins by taking the information from the APIC ID
    segment bitmaps.

    This evaluates hybrid systems correctly on the boot CPU and allows for
    cleanups and fixes in the related drivers, e.g. PERF.

The series has been extensively tested and the minimal late fallout due to
a broken ACPI/MADT table has been addressed by tightening the admission
logic further.

  • timers-ptp-2024-03-10

    27f6a9c8 · kvmclock: Unexport kvmclock clocksource · 
    Updates for timekeeping and PTP core:

  The cross-timestamp mechanism which allows to correlate hardware
  clocks uses clocksource pointers for describing the correlation.

  That's suboptimal as drivers need to obtain the pointer, which requires
  needless exports and exposing internals.

  This can be completely avoided by assigning clocksource IDs and using
  them for describing the correlated clock source.

  This update adds clocksource IDs to all clocksources in the tree which
  can be exposed to this mechanism and removes the pointer and now needless
  exports.

  This is separate from the timer core changes as it was provided to the
  PTP folks to build further changes on top.

  A related improvement for the core and the correlation handling has not
  made it this time, but is expected to get ready for the next round.

  • timers-core-2024-03-10

    8ca18367 · timer/migration: Fix quick check reporting late expiry · 
    A large set of updates and features for timers and timekeeping:

  - The hierarchical timer pull model

    When timer wheel timers are armed they are placed into the timer wheel
    of a CPU which is likely to be busy at the time of expiry. This is done
    to avoid wakeups on potentially idle CPUs.

    This is wrong in several aspects:

     1) The heuristics to select the target CPU are wrong by
        definition as the chance to get the prediction right is close
        to zero.

     2) Due to #1 it is possible that timers are accumulated on a
        single target CPU

     3) The required computation in the enqueue path is just overhead for
     	dubious value especially under the consideration that the vast
     	majority of timer wheel timers are either canceled or rearmed
     	before they expire.

    The timer pull model avoids the above by removing the target
    computation on enqueue and queueing timers always on the CPU on which
    they get armed.

    This is achieved by having separate wheels for CPU pinned timers and
    global timers which do not care about where they expire.

    As long as a CPU is busy it handles both the pinned and the global
    timers which are queued on the CPU local timer wheels.

    When a CPU goes idle it evaluates its own timer wheels:

      - If the first expiring timer is a pinned timer, then the global
      	timers can be ignored as the CPU will wake up before they expire.

      - If the first expiring timer is a global timer, then the expiry time
        is propagated into the timer pull hierarchy and the CPU makes sure
        to wake up for the first pinned timer.

    The timer pull hierarchy organizes CPUs in groups of eight at the
    lowest level and at the next levels groups of eight groups up to the
    point where no further aggregation of groups is required, i.e. the
    number of levels is log8(NR_CPUS). The magic number of eight has been
    established by experimention, but can be adjusted if needed.

    In each group one busy CPU acts as the migrator. It's only one CPU to
    avoid lock contention on remote timer wheels.

    The migrator CPU checks in its own timer wheel handling whether there
    are other CPUs in the group which have gone idle and have global timers
    to expire. If there are global timers to expire, the migrator locks the
    remote CPU timer wheel and handles the expiry.

    Depending on the group level in the hierarchy this handling can require
    to walk the hierarchy downwards to the CPU level.

    Special care is taken when the last CPU goes idle. At this point the
    CPU is the systemwide migrator at the top of the hierarchy and it
    therefore cannot delegate to the hierarchy. It needs to arm its own
    timer device to expire either at the first expiring timer in the
    hierarchy or at the first CPU local timer, which ever expires first.

    This completely removes the overhead from the enqueue path, which is
    e.g. for networking a true hotpath and trades it for a slightly more
    complex idle path.

    This has been in development for a couple of years and the final series
    has been extensively tested by various teams from silicon vendors and
    ran through extensive CI.

    There have been slight performance improvements observed on network
    centric workloads and an Intel team confirmed that this allows them to
    power down a die completely on a mult-die socket for the first time in
    a mostly idle scenario.

    There is only one outstanding ~1.5% regression on a specific overloaded
    netperf test which is currently investigated, but the rest is either
    positive or neutral performance wise and positive on the power
    management side.

  - Fixes for the timekeeping interpolation code for cross-timestamps:

    cross-timestamps are used for PTP to get snapshots from hardware timers
    and interpolated them back to clock MONOTONIC. The changes address a
    few corner cases in the interpolation code which got the math and logic
    wrong.

  - Simplifcation of the clocksource watchdog retry logic to automatically
    adjust to handle larger systems correctly instead of having more
    incomprehensible command line parameters.

  - Treewide consolidation of the VDSO data structures.

  - The usual small improvements and cleanups all over the place.

    678c607e · irqchip/riscv-intc: Fix low-level interrupt handler setup for AIA · 
    Updates for the MSI interrupt subsystem and RISC-V initial MSI support:

  - Core and platform-MSI

    The core changes have been adopted from previous work which converted
    ARM[64] to the new per device MSI domain model, which was merged to
    support multiple MSI domain per device. The ARM[64] changes are being
    worked on too, but have not been ready yet. The core and platform-MSI
    changes have been split out to not hold up RISC-V and to avoid that
    RISC-V builds on the scheduled for removal interfaces.

    The core support provides new interfaces to handle wire to MSI bridges
    in a straight forward way and introduces new platform-MSI interfaces
    which are built on top of the per device MSI domain model.

    Once ARM[64] is converted over the old platform-MSI interfaces and the
    related ugliness in the MSI core code will be removed.

  - Drivers:

    - Add a new driver for the Andes hart-level interrupt controller

    - Rework the SiFive PLIC driver to prepare for MSI suport

    - Expand the RISC-V INTC driver to support the new RISC-V AIA
      controller which provides the basis for MSI on RISC-V

    - A few fixup for the fallout of the core changes.

    The actual MSI parts for RISC-V were finalized late and have been
    post-poned for the next merge window.

  • irq-core-2024-03-10

    f7f56d59 · irqchip/ts4800: Convert to platform_driver::remove_new() callback · 
    Updates for the interrupt subsystem:

 - Core:

   - Make affinity changes immediately effective for interrupt
     threads. This reduces the impact on isolated CPUs as it pulls over the
     thread right away instead of doing it after the next hardware
     interrupt arrived.

   - Cleanup and improvements for the interrupt chip simulator

   - Deduplication of the interrupt descriptor initialization code so the
     sparse and non-sparse mode share more code.

 - Drivers:

   - A set of conversions to platform_drivers::remove_new() which gets rid
     of the pointless return value.

   - A new driver for the Starfive JH8100 SoC

   - Support for Amlogic-T7 SoCs

   - Improvement for the interrupt handling and EOI management for the
     loongson interrupt controller.

   - The usual fixes and improvements all over the place.

  • rust-6.9

    768409cf · rust: upgrade to Rust 1.76.0 · 
    Rust changes for v6.9

Another routine one in terms of features. We got two version upgrades
this time, but in terms of lines, 'alloc' changes are not very large.

Toolchain and infrastructure:

 - Upgrade to Rust 1.76.0.

   This time around, due to how the kernel and Rust schedules have
   aligned, there are two upgrades in fact. These allow us to remove two
   more unstable features ('const_maybe_uninit_zeroed' and
   'ptr_metadata') from the list, among other improvements.

 - Mark 'rustc' (and others) invocations as recursive, which fixes a new
   warning and prepares us for the future in case we eventually take
   advantage of the Make jobserver.

'kernel' crate:

 - Add the 'container_of!' macro.

 - Stop using the unstable 'ptr_metadata' feature by employing the now
   stable 'byte_sub' method to implement 'Arc::from_raw()'.

 - Add the 'time' module with a 'msecs_to_jiffies()' conversion function
   to begin with, to be used by Rust Binder.

 - Add 'notify_sync()' and 'wait_interruptible_timeout()' methods to
   'CondVar', to be used by Rust Binder.

 - Update integer types for 'CondVar'.

 - Rename 'wait_list' field to 'wait_queue_head' in 'CondVar'.

 - Implement 'Display' and 'Debug' for 'BStr'.

 - Add the 'try_from_foreign()' method to the 'ForeignOwnable' trait.

 - Add reexports for macros so that they can be used from the right
   module (in addition to the root).

 - A series of code documentation improvements, including adding
   intra-doc links, consistency improvements, typo fixes...

'macros' crate:

 - Place generated 'init_module()' function in '.init.text'.

Documentation:

 - Add documentation on Rust doctests and how they work.

KNOWN ISSUES:

- Pinephone Pro:
  - imx258 capture doesn't work after suspend/resume cycle (test)

- Pinephone:
  - You may experience p-boot display pipeline handover failures with the
    new HDMI HPD fix since (2021-10-26) if you have drivers compiled in such
    a way that parts of the sunxi DRM stack have to re-probe on boot.
    One way to workaround this is to compile everything needed for anx7688
    and display pipeline as built-in drivers.
  - Bluetooth is never powered off. Only way to power it off is to unload
    the bluetooth driver module. (rfkill or bluetoothctl power off do not
    work)

2022-11-01:
- rebased on v6.1-rc3
- add pinephone keyboard power manager driver
  - this driver manages charging cycle of both batteries and provides
    LED triggers, uevents and combined state in debugfs/kbpwr/state usable
    for summary capacity/discharge rate reporting
  - the driver optimizes for the highest power efficiency (power is used
    more directly without needless recharging of phone's battery from the
    keyboard battery)
  - the driver also performs calibration of kb battery internal resistance
    to improve reliability of capacity reporting of keyboard battery
  - the driver optionally provides emergency shutdown when both batteries
    are almost discharged
- make various PMIC drivers report battery capacity in uWh to userspace
  to make calculations for total capacity of multi-battery setup with
  different sized batteries more meaningful
- move to mainlined pinephone-keyboard driver
- ported sun6i-csi patches over to the 6.1 (base driver was changed quite
  a lot in rc2, so multicamera support needed to be rewritten from scratch)
- fixed pinephone keyboard current reporting (with large currents, the
  keyboard would sometimes report incorrect negative values due to integer
  overflow)
- renamed ppp selfie camera sensor subdevice name to be mainline compatible
- ppkb: allowed to disable special handling of FN layer via module parameter
  (to make it possible to use Fn key as another modifier key in xkb)
- hopefully final fix for quartz64-a pcie register/address ranges map
- added buffer support for af8133j magnetometer driver
- removed useless error messages
- sun4i-drm (pinephone) DRM driver fixes
  - rewritten patches that fix layer positioning and fixed additional bugs
    in the driver (reconfiguring planes while crtc was turned off led to
    corruption/stale framebuffer being scanned to the display)
- pinephone: fix power key getting stuck after resume, when pressed and
  released quickly enough (reported by Aren)

- added support for front and back camera for Pinephone Pro
- resolved clock frequency incompatibility between the sensor drivers
2022-05-21:
- rebase on v5.18-rc8
- stupid ass schematic for pinephone pro is completely confusing, which is one
  reason why world facing camera didn't work up to now. See for yourself:
  This https://megous.com/dl/tmp/39cbd011289c6818.png apparently means that
  IMX258 is connected to MIPI1_TX1/RX1 lol https://megous.com/dl/tmp/5f25b00ef0166252.png
  MIPI_RX0 is isp0 MIPI1_RX1 is isp1. Just by reading the camera sheet in the
  schematic, I happily assumed that naming signals MIPI_RX0, they actually really
  are MIPI_RX0, but alas. Anyway, I moved IMX258 sensor node in device tree
  to isp1, so that increases chances that users who have working connection
  to the sensor over I2C will have a working camera now. :) Please test and
  report back.
- some cleanup and patch re-ordering in ppp branches
- drop A64 idle states from DT (these should be auto-added by TF-A when supported;

- rebase on linus/master (5.13-rc6+)
2021-06-05:
- rebase on linus/master (5.13-rc5)
- add support for runtime calibration of minimum duty cycle of PWM backlight
  (until now it was hardcoded in device tree)
  - minimum brightness calibration instructions (default for lth_brightness is 10%,
    meaning is 'PWM duty cycle at the lowest brightness setting'):

  echo 1 > /sys/class/backlight/backlight/brightness
  echo 1 > /sys/class/backlight/backlight/device/lth_brightness
  echo 2 > /sys/class/backlight/backlight/device/lth_brightness
  echo 3 > /sys/class/backlight/backlight/device/lth_brightness

  ... increase values until you like the minimum brightness

  ... then make sure to restore this value after each boot by writing it to
  /sys/class/backlight/backlight/device/lth_brightness

- rebase on linus/master (5.13-rc2+)
2021-05-20:
- rebase on linus/master (5.13-rc2+)
- fixed up booting with fw_devlink=on (see fixes-5.13)
- applied Samuel's time travel avoidance fix https://patchwork.kernel.org/project/linux-arm-kernel/patch/20210515021439.55316-1-samuel@sholland.org/
  - this should fix occasional stalls and system hangs
- revert fine tuned OCV based capacity reporting, PMIC is not reporting OCV correctly
  so kernel has garbage input for the OCV -> capacity conversion and thus produces
  garbage output too (this stops large jumps in capacity when plugging in a charger
  and in general makes capacity reporting saner)
- fixed "NOHZ tick-stop error: Non-RCU local softirq work is pending, handler #08!!!"
- wifi driver no longer prevents dynticks from working
- improved (well..., added) suspend/resume code to anx7688 driver :)
  - fixes some issues caused by this driver ignoring the suspend/resume cycle

- raise the default minimum frequency for mbus devfreq governor
  (you can still lower it in sysfs for higher runtime power savings at the cost
  of some performance, see /sys/class/devfreq and tune it there for your distro)
2021-04-26:
- rebase on 5.12 final
- fixed behavior with dumb charger (DCP) being forced to 500mA on boot from anx7688
  driver
- disable lradc wakeup by default (lowers the power consumption in suspend)
2021-04-25:
- rebase on linus/master
- I've created a patch that disables touchscreen controller during system sleep
  reducing power consumption by about 40mW in sleep (and by 130mW when touching
  the screen in sleep)
  - before: https://megous.com/dl/tmp/0533207eed42258c.png
  - after: https://megous.com/dl/tmp/5d504d680415e2e3.png
  - those power spikes are touch controller checking if there's a finger touching
    the screen, and those dense spikes are when the finger is actually touching
    the screen

- disable MMC runtime PM again (causes issues on H5/H6 https://megous.com/dl/tmp/1eec9b1c7f03ad93.png)
- used nvmem reboot driver (suggested by Samuel in RFC patch) for rebooting to FEL,
  eMMC bootloader, various p-boot boot configs on either eMMC or SD card's bootfs filesystems,
  boot menu, etc. via reboot() syscall with extra arg (see LINUX_REBOOT_CMD_RESTART2)
  (p-boot is also updated to support this mechanism, as of 2021-02-15)
2021-02-08:

2020-12-07:
- rebased on top of 5.10-rc7
2020-12-05:
- modem power driver: add more powerup modes and change interface for dumb and fastboot powerup
  - you can now write 2, 3 or 4 to .../powered sysfs file to select differnt powerup mode from
    the normal one (1)
  - this is useful for selecting alternate userspace configurations early in boot to allow
    tracing the userspace processes from early on for reverse engineering, and in the near
    future, it will be used to switch between original and fully-FOSS userspace code
    running on the modem's APPS CPU on powerup
    - see https://xnux.eu/log/#028
2020-12-02:
- fix WiFi blocking suspend
- improve modem power driver interaction with kernel's autosleep
- shorten resume times from 1.2s to 400ms (wifi driver optimization)
2020-11-30:
- I improved the anx7688 driver to actually respect PD capabilities of the source,
  and don't overload it. This should make it more likely to work with the USB-C
  docks when docks are powered.
- Pine64 dock can provide either 500mA when powered from regular USB-A charger
  (regardless of what kind of charger it is, it can't use more current from it)
- With my 3A PD charger, Pine64 dock will advertise 2600mA and Pinephone will
  now respect this limit.
- rebase on linus/master (5.10-rc6 atm)
- increase I2C clock for sensors and touchscreen/anx7688 from 100kHz to 400kHz
- added patch from https://patchwork.kernel.org/project/dri-devel/cover/20200222024210.18697-1-yuq825@gmail.com/#23237865
  for easier GPU debugging (suggested by bshah)

My kernel's main integration branch is 'orange-pi-$VER' (this one).
No other branch is supposed to work alone. My defconfigs are tested
and work on the boards I support. Read the README.md for more info.

Only my branches based on the current mainline kernel branch are
maintained (those are usually the -rc# kernels!). You can find the
current mainline version here https://www.kernel.org/ (mainline: ...)

My prebuilt kernels can be found at https://xff.cz/kernels/ You can
use them to test that your board works, or just run them without
bothering with building everything yourself. I run them on all my
boards.

My website is https://xnux.eu and may contain useful advice.

Good luck!
