[PATCH v7 0/9] mfd: watchdog: rtc: New driver for ST's LPC IP

[Alessandro: This just needs RTC Acks now]
 
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 Device Driver model.
 
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 7:
 - Fix 2 legacy typos in the binding documentation compatible string
   examples.  
 
Version 6:
 - RTC: GPL v2 => GPL to reflect the information in the header
 - Applied another Reviewed-by from Guenter
 
Version 5:
 - Disable WDT clock over suspend
 - WDT: GPL v2 => GPL to reflect the information in the header
 - Change module name in Kconfig help and file header
 
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
