[PATCH v2 0/9] mfd: watchdog: rtc: New driver for ST's LPC IP

ST's Low Power Controller (LPC) controls two devices; watchdog and RTC.
Only one of the devices can be used at any one time, which is enforced
by the correlating MFD driver.

This driver set provides everything you need to choose one (and only
one) of the LPC devices to run per I/P block, of which there are two
on the enabled STiH407 h/w.

Version 2:
 - Only calculate keepalive once in probe()
 - Check for a 0 clk_rate
 - Set limits using predefined attributes from watchdog_device
 - CONFIG_PM => CONFIG_SLEEP
 - Call st_wdog_setup() on resume
 - Remove MFD driver -- instead rely on driver probing mechanism
   which continues attempting to bind to different drivers until
   one does not return -ENODEV

Lee Jones (9):
  mfd: dt-bindings: Provide human readable defines for LPC mode choosing
  ARM: multi_v7_defconfig: Enable support for ST's LPC Watchdog
  ARM: multi_v7_defconfig: Enable support for ST's LPC RTC
  ARM: STi: DT: STiH407: Add Device Tree node for the LPC
  watchdog: bindings: Provide ST bindings for ST's LPC Watchdog device
  watchdog: st_wdt: Add new driver for ST's LPC Watchdog
  rtc: bindings: Provide ST bindings for ST's LPC RTC device
  rtc: st: add new driver for ST's LPC RTC
  MAINTAINERS: Add Watchdog and RTC files to STI's maintainer entry
