pm+acpi-3.12-rc2
d831a005 · ·ACPI and power management fixes for 3.12-rc2 1) Four fixes for cpufreq regressions introduced by the changes that removed Device Tree parsing for CPU device nodes from cpufreq drivers from Sudeep KarkadaNagesha. 2) Two fixes for recent cpufreq regressions introduced by changes related to the preservation of sysfs attributes over system suspend/resume cycles from Viresh Kumar. 3) Fix for ACPI-based wakeup signaling in the PCI subsystem that fails to stop PME polling for devices put into the D3cold power state from Rafael J Wysocki. 4) Fix for bad interactions between cpufreq and udev on systems supporting intel_pstate where acpi-cpufreq is available as well from Yinghai Lu. / -

pm+acpi-fixes-3.12-rc1
f1728fd1 · ·ACPI and power management fixes for 3.12-rc1 1) ACPI-based PCI hotplug (ACPIPHP) fixes related to spurious events After the recent ACPIPHP changes we've seen some interesting breakage on a system that triggers device check notifications during boot for non-existing devices. Although those notifications are really spurious, we should be able to deal with them nevertheless and that shouldn't introduce too much overhead. Four commits to make that work properly. 2) Memory hotplug and hibernation mutual exclusion rework This was maent to be a cleanup, but it happens to fix a classical ABBA deadlock between system suspend/hibernation and ACPI memory hotplug which is possible if they are started roughly at the same time. Three commits rework memory hotplug so that it doesn't acquire pm_mutex and make hibernation use device_hotplug_lock which prevents it from racing with memory hotplug. 3) ACPI Intel LPSS (Low-Power Subsystem) driver crash fix The ACPI LPSS driver crashes during boot on Apple Macbook Air with Haswell that has slightly unusual BIOS configuration in which one of the LPSS device's _CRS method doesn't return all of the information expected by the driver. Fix from Mika Westerberg, for stable. 4) ACPICA fix related to Store->ArgX operation AML interpreter fix for obscure breakage that causes AML to be executed incorrectly on some machines (observed in practice). From Bob Moore. 5) ACPI core fix for PCI ACPI device objects lookup There still are cases in which there is more than one ACPI device object matching a given PCI device and we don't choose the one that the BIOS expects us to choose, so this makes the lookup take more criteria into account in those cases. 6) Fix to prevent cpuidle from crashing in some rare cases If the result of cpuidle_get_driver() is NULL, which can happen on some systems, cpuidle_driver_ref() will crash trying to use that pointer and the Daniel Fu's fix prevents that from happening. 7) cpufreq fixes related to CPU hotplug Stephen Boyd reported a number of concurrency problems with cpufreq related to CPU hotplug which are addressed by a series of fixes from Srivatsa S Bhat and Viresh Kumar. 8) cpufreq fix for time conversion in time_in_state attribute Time conversion carried out by cpufreq when user space attempts to read /sys/devices/system/cpu/cpu*/cpufreq/stats/time_in_state won't work correcty if cputime_t doesn't map directly to jiffies. Fix from Andreas Schwab. 9) Revert of a troublesome cpufreq commit Commit 7c30ed5 (cpufreq: make sure frequency transitions are serialized) was intended to address some known concurrency problems in cpufreq related to the ordering of transitions, but unfortunately it introduced several problems of its own, so I decided to revert it now and address the original problems later in a more robust way. 10) Intel Haswell CPU models for intel_pstate from Nell Hardcastle. 11) cpufreq fixes related to system suspend/resume The recent cpufreq changes that made it preserve CPU sysfs attributes over suspend/resume cycles introduced a possible NULL pointer dereference that caused it to crash during the second attempt to suspend. Three commits from Srivatsa S Bhat fix that problem and a couple of related issues. 12) cpufreq locking fix cpufreq_policy_restore() should acquire the lock for reading, but it acquires it for writing. Fix from Lan Tianyu. /

gpio-v3.12-1
65d87656 · ·This is the bulk of GPIO changes for the v3.12 series: - A new driver for the TZ1090 PDC which is used on the metag architecture. - A new driver for the Kontron ETX or COMexpress GPIO block. This is found on some ETX x86 devices. - A new driver for the Fintek Super-I/O chips, used on some x86 boards. - Added device tree probing on a few select GPIO blocks. - Drop the Exynos support from the Samsung GPIO driver. The Samsung maintainers have moved over to use the modernized pin control driver to provide GPIO for the modern platforms instead. - The usual bunch of non-critical fixes and cleanups.

pinctrl-v3.12-1
c9e3b2d8 · ·Bulk pin control changes for the v3.12 series: - Refactorings for generic pin config handling in the core. - Factor out a set of device tree utilities for use in all drivers, to parse and allocate maps from the device tree. - Some fixes to the core such as more nitpicky locking. - Pushed down config array iteration into the drivers. This patch is necessary for drivers that want to iterate over configs and pile up a stack of alterations to the same register(s), or if the driver wants to take a local spinlock when committing the configuration. - A new driver for the Texas Instruments Palmas PMIC by Laxman Dewangan. This is used on the Tegra systems. - A major cleanup and modernization of the PFC (Super Hitachi and ARM SHmobile) pin controller and subdrivers. - Support for the A20 and A31 sunxi (AllWinner) SoCs. - A huge pile of fixes and cleanups: Axel Lin, Jingoo Han Dan Carpenter, Julia Lawall and Sachin Kamat did an excellent job here.
