The DTS has no PMIC node, so just add a regulator-fixed to solve it and fix dtbs_check warning: s5pv210-smdkv210.dtb: backlight: 'power-supply' is a required property Link: https://lore.kernel.org/r/20230421095721.31857-4-krzysztof.kozlowski@linaro.org Signed-off-by: Krzysztof Kozlowski Stable-dep-of: 982655cb0e7f ("ARM: dts: samsung: s5pv210-smdkv210: correct ethernet reg addresses (split)") Signed-off-by: Sasha Levin --- arch/arm/boot/dts/s5pv210-smdkv210.dts | 8 ++++++++ 1 file changed, 8 insertions(+) diff --git a/arch/arm/boot/dts/s5pv210-smdkv210.dts b/arch/arm/boot/dts/s5pv210-smdkv210.dts index 7459e41e8ef13..ec5e18c59d3cf 100644 --- a/arch/arm/boot/dts/s5pv210-smdkv210.dts +++ b/arch/arm/boot/dts/s5pv210-smdkv210.dts @@ -55,6 +55,14 @@ backlight { default-brightness-level = <6>; pinctrl-names = "default"; pinctrl-0 = <&pwm3_out>; + power-supply = <&dc5v_reg>; + }; + + dc5v_reg: regulator-0 { + compatible = "regulator-fixed"; + regulator-name = "DC5V"; + regulator-min-microvolt = <5000000>; + regulator-max-microvolt = <5000000>; }; }; -- 2.40.1
