Subject[PATCH V3 1/4] dt-bindings: fsl: scu: add watchdog binding
Date
Add i.MX8QXP system controller watchdog binding.

Signed-off-by: Anson Huang <Anson.Huang@nxp.com>

Changes since V2:
- add fallback compatible "fsl,imx-sc-wdt" to cover other i.MX platforms with system controller
watchdog available.
- this patch depends on my thermal patch series: https://patchwork.kernel.org/patch/10827673/
