Subject: [PATCH v2 1/2] spi: dt-bindings: fsl-dspi: add dmas and dma-names properties
Add dmas and dma-names properties because dspi support dma transfer.
Fix below warnings:
arch/arm64/boot/dts/freescale/fsl-ls1028a-kontron-sl28-var1.dtb: spi@...0000: Unevaluated properties are not allowed ('dma-names', 'dmas', 'little-endian' were unexpected)
from schema $id: http://devicetree.org/schemas/spi/fsl,dspi.yaml#
Reviewed-by: Krzysztof Kozlowski <krzysztof.kozlowski@...aro.org>
