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 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().
