[v2,0/3] Add watchdog for Mstar SoCs

Message

Romain Perier May 30, 2021, 7:26 a.m. UTC

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().
