Subject[PATCH v3 08/19] dt-bindings: watchdog: fsl-imx-wdt: Add i.MX 8M compatibles
Date
DTSes with new i.MX 8M SoCs introduce their own compatibles so add them
to fix dtbs_check warnings like:

arch/arm64/boot/dts/freescale/imx8mm-var-som-symphony.dt.yaml: watchdog@30280000:
compatible:0: 'fsl,imx8mm-wdt' is not one of ['fsl,imx21-wdt']
From schema: Documentation/devicetree/bindings/watchdog/fsl-imx-wdt.yaml

arch/arm64/boot/dts/freescale/imx8mm-var-som-symphony.dt.yaml: watchdog@30280000:
compatible: ['fsl,imx8mm-wdt', 'fsl,imx21-wdt'] is too long

arch/arm64/boot/dts/freescale/imx8mm-var-som-symphony.dt.yaml: watchdog@30280000:
compatible: Additional items are not allowed ('fsl,imx21-wdt' was unexpected)
