To lower power during suspend, configure the regulators state using the same configuration found in the ChromeOS 3.8 kernel. Signed-off-by: Javier Martinez Canillas --- Changes in v4: None Changes in v3: - Use the standard suspend state binding as suggested by Mark Brown. arch/arm/boot/dts/exynos5420-peach-pit.dts | 81 ++++++++++++++++++++++++++++++ arch/arm/boot/dts/exynos5800-peach-pi.dts | 81 ++++++++++++++++++++++++++++++ 2 files changed, 162 insertions(+) diff --git a/arch/arm/boot/dts/exynos5420-peach-pit.dts b/arch/arm/boot/dts/exynos5420-peach-pit.dts index 9a050e1..8b744c7 100644 --- a/arch/arm/boot/dts/exynos5420-peach-pit.dts +++ b/arch/arm/boot/dts/exynos5420-peach-pit.dts @@ -13,6 +13,7 @@ #include #include #include +#include #include "exynos5420.dtsi" / { @@ -192,6 +193,9 @@ regulator-always-on;
