From 23c76dc666471dce5ce71b620839d2465723a7c9 Mon Sep 17 00:00:00 2001 From: Javier Martinez Canillas Date: Thu, 15 Jan 2015 00:30:49 +0900 Subject: ARM: dts: Configure regulators for suspend on exynos Peach boards The regulator core now has support to choose if a regulator has to be enabled or disabled during system suspend and also supports changing the regulator operating mode during runtime and when the system enters into sleep mode. 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 Signed-off-by: Kukjin Kim --- 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 a4c5152f6b6e..c47bb70665c1 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" / { @@ -201,6 +202,9 @@ regulator-always-on;
