Subject: [PATCH v2 0/8] watchdog: rtc: New driver(s) for ST's LPC IP
Date: Wed, 17 Dec 2014 16:45:19 +0000	[thread overview]
Message-ID: <1418834727-1602-1-git-send-email-lee.jones@linaro.org> (raw)

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
