Given this patch-set has been on the list for some time now and we
haven't heard from Alessandro in all that time, I'm going to just
apply the set and send out a pull-request to the other Maintainers.

No point waiting any longer IMHO.

> 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
