From mboxrd@z Thu Jan 1 00:00:00 1970 From: Javier Martinez Canillas Subject: [PATCH v4 14/14] ARM: dts: Configure regulators for suspend on exynos Peach boards Date: Mon, 3 Nov 2014 15:40:49 +0100 Message-ID: <1415025649-8119-15-git-send-email-javier.martinez@collabora.co.uk> References: <1415025649-8119-1-git-send-email-javier.martinez@collabora.co.uk> Return-path: In-Reply-To: <1415025649-8119-1-git-send-email-javier.martinez@collabora.co.uk> Sender: linux-samsung-soc-owner@vger.kernel.org To: Mark Brown Cc: Kukjin Kim , Chanwoo Choi , Olof Johansson , Chris Zhong , Krzysztof Kozlowski , Abhilash Kesavan , linux-samsung-soc@vger.kernel.org, linux-kernel@vger.kernel.org, devicetree@vger.kernel.org, Javier Martinez Canillas List-Id: devicetree@vger.kernel.org The regulator core now has support to choose if a regulator has to be enabled or disabled during system suspend and also the 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 --- 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;
