From mboxrd@z Thu Jan 1 00:00:00 1970 From: k.kozlowski@samsung.com (Krzysztof Kozlowski) Date: Mon, 09 Feb 2015 14:57:23 +0100 Subject: [PATCH v2] ARM: dts: exynos5420: Add maudio power domain Message-ID: <1423490243-7675-1-git-send-email-k.kozlowski@samsung.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org Add maudio power domain to Exynos 5420 DTSI file so its state could be tracked. This actually won't power down this domain because the pl330 dmaengine driver (for adma channel) uses IRQ safe runtime PM. Thus the patch should not introduce any functional change except of visibility of this domain to the system. Signed-off-by: Krzysztof Kozlowski Reviewed-by: Javier Martinez Canillas --- Changes sinve v1: 1. Use generic power domain bindings (suggested by Javier). 2. Add Javier's reviewed-by. --- arch/arm/boot/dts/exynos5420.dtsi | 8 ++++++++ 1 file changed, 8 insertions(+) diff --git a/arch/arm/boot/dts/exynos5420.dtsi b/arch/arm/boot/dts/exynos5420.dtsi index 9dc2e9773b30..28c4a2f4b991 100644 --- a/arch/arm/boot/dts/exynos5420.dtsi +++ b/arch/arm/boot/dts/exynos5420.dtsi @@ -288,6 +288,12 @@ "pclk1", "clk1", "pclk2", "clk2"; }; + mau_pd: power-domain at 100440E0 { + compatible = "samsung,exynos4210-pd"; + reg = <0x100440E0 0x20>; + #power-domain-cells = <0>; + }; + pinctrl_0: pinctrl at 13400000 { compatible = "samsung,exynos5420-pinctrl"; reg = <0x13400000 0x1000>; @@ -346,6 +352,7 @@ #dma-cells = <1>; #dma-channels = <6>; #dma-requests = <16>; + power-domains = <&mau_pd>; }; pdma0: pdma at 121A0000 { @@ -415,6 +422,7 @@ pinctrl-names = "default"; pinctrl-0 = <&i2s0_bus>; status = "disabled"; + power-domains = <&mau_pd>; }; i2s1: i2s at 12D60000 { -- 1.9.1
