8343284d61 mfd: atmel-flexcom: Create include file with macros used by DT bindings
This patch defines some macros to be used as value for the
"atmel,flexcom-mode" DT property. This value is then written into
the Operating Mode (OPMODE) bit field of the Flexcom Mode Register.

6f2536141c mfd: dt-bindings: Provide human readable define for Clocksource mode
ST's Low Power Controller can now operate in three supported modes;
Watchdog, Real Time Clock and most recently as a Clocksource.  This new

This patch add support for select accessory detect mode to HPDETL or HPDETR.
Arizona provides a headphone detection circuit on the HPDETL and HPDETR pins
to measure the impedance of an external load connected to the headphone.

Depending on board design, headphone detect pins can change to HPDETR or HPDETL.

5974b794cb dt/bindings: Binding documentation for Palmas clk32kg and clk32kgaudio clocks
Palmas class of devices can provide 32K clock(s) to be used by other devices
on the board. Depending on the actual device the provided clocks can be:
CLK32K_KG and CLK32K_KGAUDIO
or only one:
CLK32K_KG (TPS659039 for example)

Use separate compatible flags for the two 32K clock.
A system which needs or have only one of the 32k clock from
Palmas will need to add node(s) for each clock as separate section
in the dts file.
The two compatible property is:
"ti,palmas-clk32kg" for clk32kg clock
"ti,palmas-clk32kgaudio" for clk32kgaudio clock

Apart from the register control of the clocks - which is done via
the clock API there is a posibility to enable the external sleep
control. In this way the clock can be enabled/disabled on demand by the
user of the clock.

db0b2d0116 For the 3.13 merge window we have a couple of new drivers for the AMS
AS3722 PMIC and for STMicroelectronics STw481x PMIC.
 
 Although this is a smaller update than usual, we also have:
 
 - Device tree support for the max77693 driver.
 
 - linux/of.h inclusion for all DT compatible MFD drivers, to avoid build
   breakage in the future.
 
 - Support for Intel Wildcat Point-LP PCH through the lpc_ich driver.
 
 - A small arizona update for new wm5110 DSP registers and a few fixes.
 
 - A small palmas update as well, including an of_device table addition
   and a few minor fixes.
 
 - Two small mfd-core changes, one including a memory leak fix for when
   mfd_add_device() fails.
 
 - Our usual round of minor cleanups and janitorial fixes.
