Update the binding accordingly, in this case the panels connected to the veyron boards have a symmetric power sequence, hence the same value is used. Signed-off-by: Enric Balletbo i Serra Acked-by: Pavel Machek --- Changes since v5: - None. Changes since v4: - Rebased on top of mainline. Changes since v3: - Use new -ms names for proprieties. Changes since v2: - Use new names for proprieties. Changes since v1: - Add this new patch to fix current binding on veyron. --- arch/arm/boot/dts/rk3288-veyron-chromebook.dtsi | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/arch/arm/boot/dts/rk3288-veyron-chromebook.dtsi b/arch/arm/boot/dts/rk3288-veyron-chromebook.dtsi index d752a315f884..5a8c7f3abb38 100644 --- a/arch/arm/boot/dts/rk3288-veyron-chromebook.dtsi +++ b/arch/arm/boot/dts/rk3288-veyron-chromebook.dtsi @@ -96,7 +96,8 @@ pinctrl-names = "default"; pinctrl-0 = <&bl_en>; pwms = <&pwm0 0 1000000 0>; - pwm-delay-us = <10000>; + post-pwm-on-delay-ms = <10>; + pwm-off-delay-ms = <10>; }; gpio-charger {
