It would be great missing net-next was pointed out by checkpatch.pl. Best regards, Krzysztof

FWIW, I'd have taken the patch as is. There isn't much the current build tester can do for dt-bindings, anyway. But thanks for the resend :) I was wondering about checkpatch, too, but haven't come up with any great solution. The problem is kind of at an intersection of checkpatch and get_maintainer.

Some boards use SJA1105 Ethernet Switch with SPI CPHA, while ones with SJA1110 use SPI CPOL, so document this to fix dtbs_check warnings: arch/arm64/boot/dts/freescale/fsl-lx2160a-bluebox3.dtb: ethernet-switch@0: Unevaluated properties are not allowed ('spi-cpol' was unexpected) Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org> Reviewed-by: Conor Dooley <conor.dooley@microchip.com> --- Changes since v4: 1.
