I just wanted to let you know that the warning reported by Rob's bot is very old. Running "make dtbs_check DT_SCHEMA_FILES=trivial-devices.yaml" on the existing tree: DTC [C] arch/arm/boot/dts/rockchip/rv1108-elgin-r1.dtb rv1108-elgin-r1.dtb: dac@0: 'spi-cpha', 'spi-cpol' do not match any of the regexes: 'pinctrl-[0-9]+' from schema $id: http://devicetree.org/schemas/trivial-devices.yaml# So we are not making things worse in this aspect. I can work on removing the warnings as an incremental patch, if you agree. Regards, Fabio Estevam
