Subject: [PATCH] dt-bindings: watchdog: img,pdc-wdt: Convert to dtschema
Convert txt bindings of ImgTec's PDC watchdog timer to dtschema to allow
for validation.
Signed-off-by: Shresth Prasad <shresthprasad7@...il.com>
---
The binding has been checked and tested against `img/pistachio_marduk.dts`
with no errors or warnings.
