[V3,1/6] dt-bindings: serial: fsl-imx-uart: add missing properties

Commit Message

Stefan Wahren April 14, 2023, 9:19 a.m. UTC

Currently the dtbs_check for imx generates warnings like this:

serial@7000c000: Unevaluated properties are not allowed
('clock-names', 'clocks', 'dma-names', 'dmas' were unexpected)

So add the missing properties to the devicetree binding.
