A test with the command below gives these errors: arch/arm64/boot/dts/rockchip/rk3308-evb.dt.yaml: serial@ff0d0000: compatible: ['rockchip,rk3308-uart', 'snps,dw-apb-uart'] is not valid under any of the given schemas arch/arm64/boot/dts/rockchip/rk3308-roc-cc.dt.yaml: serial@ff0a0000: compatible: ['rockchip,rk3308-uart', 'snps,dw-apb-uart'] is not valid under any of the given schemas The compatible property for the Rockchip rk3308 uart was somehow never added to the documention. Fix this error by adding 'rockchip,rk3308-uart' to snps-dw-apb-uart.yaml. make ARCH=arm64 dtbs_check DT_SCHEMA_FILES=Documentation/devicetree/bindings/serial/ snps-dw-apb-uart.yaml Signed-off-by: Johan Jonker <jbx6244@xxxxxxxxx> --- Documentation/devicetree/bindings/serial/snps-dw-apb-uart.yaml | 1 + 1 file changed, 1 insertion(+) diff --git a/Documentation/devicetree/bindings/serial/snps-dw-apb-uart.yaml b/Documentation/devicetree/bindings/serial/snps-dw-apb-uart.yaml index b42002542..b962f8db4 100644 --- a/Documentation/devicetree/bindings/serial/snps-dw-apb-uart.yaml +++ b/Documentation/devicetree/bindings/serial/snps-dw-apb-uart.yaml @@ -27,6 +27,7 @@ properties: - rockchip,rk3066-uart - rockchip,rk3188-uart - rockchip,rk3288-uart + - rockchip,rk3308-uart - rockchip,rk3328-uart - rockchip,rk3368-uart - rockchip,rk3399-uart -- 2.11.0
