The binding dictates using 3 pwm-cells. Adhere to that. This fixes the following dtbs_check warnings: arch/arm/boot/dts/nxp/imx/imx6dl-nitrogen6x.dtb: pwm@2080000: #pwm-cells:0:0: 3 was expected from schema : http://devicetree.org/schemas/pwm/imx-pwm.yaml# arch/arm/boot/dts/nxp/imx/imx6dl-nitrogen6x.dtb: pwm@208c000: #pwm-cells:0:0: 3 was expected from schema : http://devicetree.org/schemas/pwm/imx-pwm.yaml# arch/arm/boot/dts/nxp/imx/imx6q-nitrogen6x.dtb: pwm@2080000: #pwm-cells:0:0: 3 was expected from schema : http://devicetree.org/schemas/pwm/imx-pwm.yaml# arch/arm/boot/dts/nxp/imx/imx6q-nitrogen6x.dtb: pwm@208c000: #pwm-cells:0:0: 3 was expected from schema : http://devicetree.org/schemas/pwm/imx-pwm.yaml# Signed-off-by: Uwe Kleine-König <u.kleine-koenig@xxxxxxxxxxxxxx> --- arch/arm/boot/dts/nxp/imx/imx6qdl-nitrogen6x.dtsi | 6 ++---- 1 file changed, 2 insertions(+), 4 deletions(-) diff --git a/arch/arm/boot/dts/nxp/imx/imx6qdl-nitrogen6x.dtsi b/arch/arm/boot/dts/nxp/imx/imx6qdl-nitrogen6x.dtsi index f278b14911ce..121177273dd0 100644 --- a/arch/arm/boot/dts/nxp/imx/imx6qdl-nitrogen6x.dtsi +++ b/arch/arm/boot/dts/nxp/imx/imx6qdl-nitrogen6x.dtsi @@ -134,7 +134,7 @@ sound { backlight_lcd: backlight-lcd { compatible = "pwm-backlight"; - pwms = <&pwm1 0 5000000>; + pwms = <&pwm1 0 5000000 0>; brightness-levels = <0 4 8 16 32 64 128 255>; default-brightness-level = <7>; power-supply = <®_3p3v>; @@ -143,7 +143,7 @@ backlight_lcd: backlight-lcd { backlight_lvds: backlight-lvds { compatible = "pwm-backlight"; - pwms = <&pwm4 0 5000000>; + pwms = <&pwm4 0 5000000 0>; brightness-levels = <0 4 8 16 32 64 128 255>; default-brightness-level = <7>; power-supply = <®_3p3v>; @@ -596,7 +596,6 @@ &pcie { }; &pwm1 { - #pwm-cells = <2>; pinctrl-names = "default"; pinctrl-0 = <&pinctrl_pwm1>; status = "okay"; @@ -609,7 +608,6 @@ &pwm3 { }; &pwm4 { - #pwm-cells = <2>; pinctrl-names = "default"; pinctrl-0 = <&pinctrl_pwm4>; status = "okay"; -- 2.43.0
