Run 'make dt_binding_check'. That is what I'm doing. make -f Makefile -j5 -l4 ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- KBUILD_OUTPUT=/home/linus/linux-stericsson/build-ux500 dt_binding_check CHKDT Documentation/devicetree/bindings/display/panel/sony,acx424akp.yaml CHKDT Documentation/devicetree/bindings/display/dsi-controller.yaml SCHEMA Documentation/devicetree/bindings/processed-schema.yaml (...) I'm a bit unsure how this thing works. Are the several passes? Because later on this breaks because of an unrelated error in the bindings upstream: /home/linus/linux-stericsson/Documentation/devicetree/bindings/regulator/fixed-regulator.yaml: properties:compatible:enum:0: {'const': 'regulator-fixed'} is not of type 'string' /home/linus/linux-stericsson/Documentation/devicetree/bindings/regulator/fixed-regulator.yaml: properties:compatible:enum:1: {'const': 'regulator-fixed-clock'} is not of type 'string' (...) This is v5.4-rc1. Is there any way I can selectively make dt_bindings_check just target the files I wanna check as any brokenness upstream cause problems like this? (And I assume that will keep happening.) Yours, Linus Walleij

This adds device tree bindings for the Sony ACX424AKP panel. Let's use YAML. Cc: devicetree@vger.kernel.org Signed-off-by: Linus Walleij <linus.walleij@linaro.org> --- ChangeLog v3->v4: - Adjust to adjusted DSI bindings. ChangeLog v2->v3: - Put the example inside a dsi-controller so we have a complete example that verifies to the DSI panel generic binding. ChangeLog v1->v2: - Suggest a stand-alone YAML bindings file for DSI panels in a separate patch, and use that to reference the boolean "enforce-video-mode" attribute for DSI panels --- .../display/panel/sony,acx424akp.yaml | 49 +++++++++++++++++++ 1 file changed, 49 insertions(+) create mode 100644 Documentation/devicetree/bindings/display/panel/sony,acx424akp.yaml -- 2.21.0
