It doesn't for me... With: make dt_binding_check -j32 -s -W 2 I get the following output: /home/ryan/Projects/Develop/RG35XX+/kernel/linux/Documentation/devicetree/bindings/display/panel/anbernic,wl-355608-a8.example.dtb: spi: 'num-chipselects' is a required property from schema $id: http://devicetree.org/schemas/spi/spi-gpio.yaml# /home/ryan/Projects/Develop/RG35XX+/kernel/linux/Documentation/devicetree/bindings/display/panel/anbernic,wl-355608-a8.example.dtb: spi: 'sck-gpios' is a required property from schema $id: http://devicetree.org/schemas/spi/spi-gpio.yaml# The relevant section from spi-gpio.yaml seems to be: required: - compatible - num-chipselects - sck-gpios I am happy to leave this out if a simpler example is desired, but alternately if the chipselects/sck-gpios should stay then I would suggest a better example would include the mosi/miso/cs GPIOs as well which would make the example functional.

make dt_bindings_check reports that sck-gpios and num-chipselects are required for spi nodes, therefore add these to the example. Signed-off-by: Ryan Walklin <ryan@testtoast.com> --- .../bindings/display/panel/anbernic,rg35xx-panel.yaml | 3 +++ 1 file changed, 3 insertions(+)
