Cc: Marek Szyprowski Cc: Krzysztof Kozlowski Cc: Chanwoo Choi Signed-off-by: Anand Moon --- Changes from previos patch [0] https://patchwork.kernel.org/patch/10712549/ Set all the WAKEUP source regulator in suspend-on state. LD04, LD012, LD015, LD020, LD022 Set all the non used regulator in suspend-odd state LD02, LD03, LD05, LD06, LD07, LD011, LD013, LDO14, LD016 BUCK5, BUCK6, BUCK7 and not confirable as per driver max77686-regulator Tested on microSD card and it resumes correcly after suspend. eMMC is not able to resume after entering into suspend state, which need to be investigated and how to debug more. --- .../boot/dts/exynos4412-odroid-common.dtsi | 63 +++++++++++++++++++ arch/arm/boot/dts/exynos4412-odroidu3.dts | 3 + 2 files changed, 66 insertions(+) diff --git a/arch/arm/boot/dts/exynos4412-odroid-common.dtsi b/arch/arm/boot/dts/exynos4412-odroid-common.dtsi index 08d3a0a7b4eb..e984461c37d9 100644 --- a/arch/arm/boot/dts/exynos4412-odroid-common.dtsi +++ b/arch/arm/boot/dts/exynos4412-odroid-common.dtsi @@ -288,6 +288,9 @@ regulator-min-microvolt = <1800000>;
