Also in:

Subsystem:
open firmware and flattened device tree bindings, the rest, watchdog device drivers · Maintainers:
Rob Herring, Krzysztof Kozlowski, Conor Dooley, Linus Torvalds, Wim Van Sebroeck, Guenter Roeck
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)
