It adds a basic watchdog driver, the corresponding devicetree bindings and its documentation. This work has been co-developed with Daniel Palmer. Changes since v2: - Renamed the dt-bindings documentation to mstar,msc313e-wdt.yaml - Fixed the subject of the first commit - Dropped unused dt labels 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().
