I do believe we always have pinctrl-names on top in most dts files, as it describes what the -0, -1 etc are, i.e. pinctrl-names = "statename-for-0", "statename-for-1", "statename-for-2"... pinctrl-0 = pinctrl-1 = Heiko > arch/arm64/boot/dts/rockchip/rk3566-quartz64-a.dt.yaml: spi@fe610000: > pinctrl-names:1: 'sleep' was expected > From schema: /Documentation/devicetree/bindings/spi/spi-rockchip.yaml > > Missing "high_speed" support? > > spi: rockchip: set higher io driver when sclk higher than 24MHz > https://github.com/rockchip-linux/kernel/commit/7e4349ec9d70dbcfe7f78125700d2685539ea1bd > > > + pinctrl-0 = <&spi0m0_cs0 &spi0m0_cs1 &spi0m0_pins>; > > > + pinctrl-1 = <&spi0m0_cs0 &spi0m0_cs1 &spi0m0_pins_hs>; > > Missing Linux mainline driver and document support?
