From: Krzysztof Kozlowski <krzysztof.kozlowski@xxxxxxxxxxxxx> [ Upstream commit 75121e1dc9fe4def41e63d57f6a53749b88006ed ] There is no "max_brightness" property. This brings the intentional brightness reduce of green LED and dtschema checks as well: arch/arm/boot/dts/exynos5410-odroidxu.dt.yaml: led-controller-1: led-1: 'max-brightness' is a required property Fixes: 719f39fec586 ("ARM: dts: exynos5422-odroidxu3: Hook up PWM and use it for LEDs") Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@xxxxxxxxxxxxx> Link: https://lore.kernel.org/r/20210505135941.59898-3-krzysztof.kozlowski@xxxxxxxxxxxxx Signed-off-by: Sasha Levin <sashal@xxxxxxxxxx> --- arch/arm/boot/dts/exynos54xx-odroidxu-leds.dtsi | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/arch/arm/boot/dts/exynos54xx-odroidxu-leds.dtsi b/arch/arm/boot/dts/exynos54xx-odroidxu-leds.dtsi index 2fc3e86dc5f7..982752e1df24 100644 --- a/arch/arm/boot/dts/exynos54xx-odroidxu-leds.dtsi +++ b/arch/arm/boot/dts/exynos54xx-odroidxu-leds.dtsi @@ -22,7 +22,7 @@ * Green LED is much brighter than the others * so limit its max brightness */ - max_brightness = <127>; + max-brightness = <127>; linux,default-trigger = "mmc0"; }; @@ -30,7 +30,7 @@ label = "blue:heartbeat"; pwms = <&pwm 2 2000000 0>; pwm-names = "pwm2"; - max_brightness = <255>; + max-brightness = <255>; linux,default-trigger = "heartbeat"; }; }; -- 2.30.2
