From 10ea1f18334ebf353ec283bba6f78c882281fcb2 Mon Sep 17 00:00:00 2001 From: Chanwoo Choi Date: Tue, 18 Mar 2014 06:25:58 +0900 Subject: [PATCH] ARM: dts: Add GPS_ALIVE power domain for exynos4x12 This patch add GPS_ALIVE power domain for Exynos4x12 SoC. GPS_ALIVE power domain include GPS_BLK for GPS IP. Exynos SoC used generic power-domain driver to control power domain. After completed kernel booting, Exynos power-domain driver disable un-used power domain to reduce power-consumption/leak. If GPS_ALIVE power domain isn't registered to Exynos power-domain driver, happen power-leakage because GPS_ALIVE_CONFIGURATION is default power on state. - 0x10023D00 : GPS_ALIVE_CONFIGURATION register address Signed-off-by: Chanwoo Choi Signed-off-by: Kyungmin Park Reviewed-by: Tomasz Figa Signed-off-by: Kukjin Kim --- arch/arm/boot/dts/exynos4.dtsi | 5 +++++ 1 file changed, 5 insertions(+) diff --git a/arch/arm/boot/dts/exynos4.dtsi b/arch/arm/boot/dts/exynos4.dtsi index 28b5ec79f339..0401f4dba2a2 100644 --- a/arch/arm/boot/dts/exynos4.dtsi +++ b/arch/arm/boot/dts/exynos4.dtsi @@ -86,6 +86,11 @@ reg = <0x10023CE0 0x20>; }; + pd_gps_alive: gps-alive-power-domain@10023D00 { + compatible = "samsung,exynos4210-pd"; + reg = <0x10023D00 0x20>; + }; + gic: interrupt-controller@10490000 { compatible = "arm,cortex-a9-gic"; #interrupt-cells = <3>; -- 2.20.1
