The datasheet specifies a pwm delay of 200 ms, so update the PMW delay proprieties accordingly. Signed-off-by: Enric Balletbo i Serra --- Heiko, I'm not able to test this patch in a minnie device because I don't have one, so could you do a quick try, please? Changes since v2: - Use new names for proprieties. Changes since v1: - Add this new patch as minnie has differents timings arch/arm/boot/dts/rk3288-veyron-minnie.dts | 2 ++ 1 file changed, 2 insertions(+) diff --git a/arch/arm/boot/dts/rk3288-veyron-minnie.dts b/arch/arm/boot/dts/rk3288-veyron-minnie.dts index 544de60..a5b7387 100644 --- a/arch/arm/boot/dts/rk3288-veyron-minnie.dts +++ b/arch/arm/boot/dts/rk3288-veyron-minnie.dts @@ -123,6 +123,8 @@ 240 241 242 243 244 245 246 247 248 249 250 251 252 253 254 255>; power-supply = <&backlight_regulator>; + post-pwm-on-delay-us = <20000>; + pwm-off-delay-us = <20000>; }; &emmc { -- 2.9.3
