1931ee143b Revert "drivers: of: add initialization code for dma reserved memory"
This reverts commit 9d8eab7af7. There is
still no consensus on the bindings for the reserved memory and various
drawbacks of the proposed solution has been shown, so the best now is to
revert it completely and start again from scratch later.

Pull ARM SoC fixes from Olof Johansson:
 "We have a fairly large batch of fixes this time around, mostly just
  due to various platforms all having a fix or two more than usual.

  Worth pointing out are:

   - A fix for EDMA on Davinci/OMAP where channel allocation broke with
     the DT conversion.  Due to some miscommunication we didn't
     understand the impact of the breakage, so we were pushing back on
     it for 3.12, but it sounds like it's actually breaking quite a few
     people out there.

   - A bunch of fixes for Marvell platforms, some straggling fixes for
     merge window fallout and some fixes for a couple of the platforms
     (Netgear RN102 in particular).

   - A fix for a race between multi-cluster power management and cpu
     hotplug on Versatile Express.

  And a bunch of other smaller fixes that all add up.

  We'll be switching over into stricter regressions-only mode from here
  on out"

Currently IEEE 1588 timer reference clock source is determined through
hard-coded value in gianfar_ptp driver. This patch allows to select ptp
clock source by means of device tree file node.

For instance:

	fsl,cksel = <0>;

for using external (TSEC_TMR_CLK input) high precision timer
reference clock.

Other acceptable values:

	<1> : eTSEC system clock
	<2> : eTSEC1 transmit clock
	<3> : RTC clock input

When this attribute isn't used, eTSEC system clock will serve as
IEEE 1588 timer reference clock.

According to a recent thread [1] on the linux-serial

Move the documentation of qca,ar9330-uart to the

5892cd135e drivers: net: cpsw-phy-sel: Add new driver for phy mode selection for cpsw
The cpsw currently lacks code to properly set up the hardware interface
mode on AM33xx. Other platforms might be equally affected.

Usually, the bootloader will configure the control module register, so
probably that's why such support wasn't needed in the past. In suspend
mode though, this register is modified, and so it needs reprogramming
after resume.

This patch adds a new driver in which hardware interface can configure
correct register bits when the slave is opened.

The AM33xx also has a bit for each slave to configure the RMII reference
clock direction. Setting it is now supported by a per-slave DT property.

This code path introducted by this patch is currently exclusive for
am33xx and same can be extened to various platforms via the DT compatibility
property.

df1d0584b2 ARM: shmobile: update SDHI DT compatibility string to the <unit>-<soc> format
Currently DT compatibility strings of both types can be found in the kernel
sources: <unit>-<soc> and <soc>-<unit>, whereas a unique format should be
followed and the former one is preferred. This patch converts the SDHI
MMC driver and its users to the common standard. This is safe for now, since
ATM no real products are using this driver with DT.

a22a0fdba4 Merge tag 'for-v3.12' of git://git.infradead.org/battery-2.6
Pull battery/power supply driver updates from Anton Vorontsov:
 "New drivers:

   - APM X-Gene system reboot driver by Feng Kan and Loc Ho (APM).

   - Qualcomm MSM reboot/poweroff driver by Abhimanyu Kapur (Codeaurora).

   - Texas Instruments BQ24190 charger driver by Mark A.  Greer (Animal
     Creek Technologies).

   - Texas Instruments TWL4030 MADC battery driver by Lukas Märdian and
     Marek Belisko (Golden Delicious Computers).  The driver is used on
     Freerunner GTA04 phones.

  Highlighted fixes and improvements:

   - Suspend/wakeup logic improvements: power supply objects will block
     system suspend until all power supply events are processed.  Thanks
     to Zoran Markovic (Linaro), Arve Hjonnevag and Todd Poynor (Google)"

31f7c3a688 Merge tag 'devicetree-for-linus' of git://git.secretlab.ca/git/linux
Pull device tree core updates from Grant Likely:
 "Generally minor changes.  A bunch of bug fixes, particularly for
  initialization and some refactoring.  Most notable change if feeding
  the entire flattened tree into the random pool at boot.  May not be
  significant, but shouldn't hurt either"

Tim Bird questions whether the boot time cost of the random feeding may
be noticeable.  And "add_device_randomness()" is definitely not some
speed deamon of a function.
