Third version of this series. I just rebased it on v6.16-rc1, dropped the
binding patch (already applied upstream) and took RB/AB tags for the
devicetree patch.
---
Changes in v3:
- all: rebase on v6.16-rc1
- bindings: remove patch
- devicetree: take "Acked-by: Oliver Graute <oliver.graute@kococonnector.com>"
- devicetree: take "Reviewed-by: Frank Li <Frank.Li@nxp.com>"
- Link to v2: https://lore.kernel.org/r/20250414-imx8qm-watchdog-v2-0-449265a9da4e@bootlin.com
Changes in v2:
- bindings: take "Acked-by: Rob Herring (Arm) <robh@kernel.org>"
- bindings: take "Reviewed-by: Frank Li <Frank.Li@nxp.com>"
- devicetree: move the watchdog node just after thermal-sensor
- Link to v1: https://lore.kernel.org/r/20250407-imx8qm-watchdog-v1-0-20c219b15fd2@bootlin.com
