This patches series adds a new driver for the watchdog found in the Mstar
MSC313e SoCs and newer. It adds a basic watchdog driver, the
corresponding devicetree bindings and its documentation.
This work has been co-developed with Daniel Palmer.
Changes since v1:
- Dropped "depends OF" from Kconfig (not required)
- Dropped unneeded include files
- Re-ordered include files
- Compute timeout_max dynamically from the probe function to avoid
an overflow in _start().

This adds the documentation for the devicetree bindings of the Mstar
MSC313e watchdog driver, found from MSC313e SoCs and newer.

This adds the definition of both an oscillator at 12Mhz required by the
the watchdog and the watchdog device_node.
