[PATCH v2 0/8] watchdog: rtc: New driver(s) 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 a Device Tree property.

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.

v1 => v2:
Suggestions fixed up:
Arnd: No need for a separate MFD driver. If you return -ENODEV
really_probe() will continue looking for an suitable alternative.

David: Power Management improvements.

Guenter: Use Watchdog Framework's maximum timeout checker and only request
clock rate once during .probe(), as the clock rate will not
change.

Lee Jones (8):
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
