Subject[PATCH v4 0/9] mfd: watchdog: rtc: New driver for ST's LPC IP
Date
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 4:
- Use {readl,writel}_relaxed() calls
- Add Guenter's Reviewed-by
- Rebased onto v4.0-rc1

Version 3:
- Move Regmap pointer into core device data structure
- Remove error message from devm_ioremap_resource

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
