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.

Pull MFD updates from Samuel Ortiz:
"For the 3.13 merge window we have a couple of new drivers for the AMS
