Chen-Yu Tsai 768a87c8e1 mfd: axp20x: Update DT bindings with AXP22x compatibles
Add AXP221 to the list of supported devices.

Also replace any mention of AXP20x in the document with a
generic "PMIC".

Linus Torvalds 5c73cc4b6c ARM: DT updates for v4.1
As always, this tends to be one of our bigger branches. There are lots of
 updates this release, but not that many jumps out as something that needs
 more detailed coverage. Some of the highlights are:
 
 - DTs for the new Annapurna Labs Alpine platform
 - More graphics DT pieces falling into place on Exynos, bridges, clocks.
 - Plenty of DT updates for Qualcomm platforms for various IP blocks
 - Some churn on Tegra due to switch-over to tool-generated pinctrl data
 - Misc fixes and updates for Atmel at91 platforms
 - Various DT updates to add IP block support on Broadcom's Cygnus platforms
 - More updates for Renesas platforms as DT support is added for various IP
   blocks (IPMMU, display, audio, etc).

Linus Torvalds 18656782a8 ARM: SoC driver updates

 and for some reason could not get merged through the respective
 subsystem maintainer tree.
 
 This time around, much of this is for at91, with the bulk of it being syscon
 and udc drivers.
 
 Also, there's:
 - coupled cpuidle support for Samsung Exynos4210
 - Renesas 73A0 common-clk work
 - of/platform changes to tear down DMA mappings on device destruction
 - a few updates to the TI Keystone knav code

to save data which need to be kept when the system is powered down and
VDD-core is maintained by an external battery.

A typical usage is the RTT block (when used as an RTC) which needs one of
those registers to save the current time.

Linus Walleij bc80436033 mfd: tc3589x: Add device tree bindings
This defines the device tree bindings for the Toshiba TC3589x
series of multi-purpose expanders. Only the stuff I can test
is defined: GPIO and keypad. Others may implement more
subdevices further down the road.

This is to complement
commit a435ae1d51
"mfd: Enable the tc3589x for Device Tree" which left off
the definition of the device tree bindings.

Chen-Yu Tsai 4eb9560b8f mfd: sun6i-prcm: Add support for Allwinner A23 PRCM
The Allwinner A23 SoC has a PRCM unit like the previous A31 SoC.
The differences are the AR100 clock can no longer be modified,
the APB0 clock has different divisors, and some clock gates are
gone.

This patch adds a compatible with a modified subdevice list for
the A23.
