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 --- 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 28b5ec7..0401f4d 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>;
