I assume that is why > the 'big-endian' property isn't 'fsl,big-endian'. We should read it as that 'big-endian' is a generic property defined by generic bindings - bindings/regmap/regmap.txt, and we just reference the bindings in fsl-imx-wdt.txt. Taking mmc bindings as example, bindings/mmc/mmc.txt defines generic bindings, while bindings/mmc/fsl-imx-esdhc.txt defines i.MX vendor specific properties, which should ideally have vendor prefix.
