The A80 Optimus board has 3 usable LEDs that are controlled via GPIO.
This patch adds support for 2 of them which are driver by GPIOs in the
main pin controller. The remaining one uses GPIO from the R_PIO
controller, which we don't support yet.

fixes and enhancements to existing drivers as well as new drivers. This
tag contains a bit more arch code than I usually take due to some OMAP2+
changes. Additionally it contains the restart notifier handlers which
are merged as a dependency into several trees.
The PXA changes are the only messy part. Due to having a stable tree I
had to revert one patch and follow up with one more fix near the tip of
this tag. Some dead code is introduced but it will soon become live code
after 3.18-rc1 is released as the rest of the PXA family is converted
over to the common clock framework.
Another trend in this tag is that multiple vendors have started to push
the complexity of changing their CPU frequency into the clock driver,
whereas this used to be done in CPUfreq drivers.
Changes to the clk core include a generic gpio-clock type and a
clk_set_phase() function added to the top-level clk.h api. Due to some
confusion on the fbdev mailing list the kernel boot parameters
documentation was updated to further explain the clk_ignore_unused
parameter, which is often required by users of the simplefb driver.
Finally some fixes to the locking around the clock debugfs stuff was
done to prevent deadlocks when interacting with other subsystems.

- Rework the handling of wakeup IRQs by the IRQ core such that
all of them will be switched over to "wakeup" mode in
suspend_device_irqs() and in that mode the first interrupt
will abort system suspend in progress or wake up the system
if already in suspend-to-idle (or equivalent) without executing
any interrupt handlers. Among other things that eliminates the
wakeup-related motivation to use the IRQF_NO_SUSPEND interrupt
flag with interrupts which don't really need it and should not
use it (Thomas Gleixner and Rafael J Wysocki).
- Switch over ACPI to handling wakeup interrupts with the help
of the new mechanism introduced by the above IRQ core rework
(Rafael J Wysocki).

not used, add DT support and add a generic mechanism by which
devices can be added to PM domains automatically during
enumeration (Ulf Hansson, Geert Uytterhoeven and Tomasz Figa).

(Maciej Matraszek).
- ACPICA update to upstream version 20140828. Included are updates
related to the SRAT and GTDT tables and the _PSx methods are in
the METHOD_NAME list now (Bob Moore and Hanjun Guo).
- Add _OSI("Darwin") support to the ACPI core (unfortunately, that
can't really be done in a straightforward way) to prevent
Thunderbolt from being turned off on Apple systems after boot
(or after resume from system suspend) and rework the ACPI Smart
Battery Subsystem (SBS) driver to work correctly with Apple
platforms (Matthew Garrett and Andreas Noever).

to it and making it avoid using UART RTS override with Auto Flow
Control (Heikki Krogerus).
- ACPI backlight updates removing the video_set_use_native_backlight
quirk which is not necessary any more, making the code check the
list of output devices returned by the _DOD method to avoid
creating acpi_video interfaces that won't work and adding a quirk
for Lenovo Ideapad Z570 (Hans de Goede, Aaron Lu and Stepan Bujnak).

Pull ACPI and power management updates from Rafael Wysocki:
"Features-wise, to me the most important this time is a rework of
wakeup interrupts handling in the core that makes them work
consistently across all of the available sleep states, including
suspend-to-idle. Many thanks to Thomas Gleixner for his help with
this work.
Second is an update of the generic PM domains code that has been in
need of some care for quite a while. Unused code is being removed, DT
support is being added and domains are now going to be attached to
devices in bus type code in analogy with the ACPI PM domain. The
majority of work here was done by Ulf Hansson who also has been the
most active developer this time.
Apart from this we have a traditional ACPICA update, this time to
upstream version 20140828 and a few ACPI wakeup interrupts handling
patches on top of the general rework mentioned above. There also are
several cpufreq commits including renaming the cpufreq-cpu0 driver to
cpufreq-dt, as this is what implements generic DT-based cpufreq
support, and a new DT-based idle states infrastructure for cpuidle.
In addition to that, the ACPI LPSS driver is updated, ACPI support for
Apple machines is improved, a few bugs are fixed and a few cleanups
are made all over.
Finally, the Adaptive Voltage Scaling (AVS) subsystem now has a tree
maintained by Kevin Hilman that will be merged through the PM tree.
Numbers-wise, the generic PM domains update takes the lead this time
with 32 non-merge commits, second is cpufreq (15 commits) and the 3rd
place goes to the wakeup interrupts handling rework (13 commits).

Regulators for MMC2 (SD card) are PVDD_TFLASH_2V8 (LDO19) for vmmc
and PVDD_APIO_MMCOFF_2V8 (LDO13) for vqmmc. Currently the device
tree entry for MMC2 uses PVDD_PRE_1V8 (LDO10) for vmmc and vqmmc is
not specified. Fix it.
Without this patch:
- "mmc: dw_mmc: use mmc_regulator_get_supply to handle regulators"
patch causes a SD card detection to fail
- "mmc: dw_mmc: Support voltage changes" patch causes a boot hang
This patch fixes both above problems.
