From: Mark Brown <broonie@xxxxxxxxxx> Rather than requiring each board to explicitly disable the I2S controllers it is not using instead require boards to enable those that they are using. This is required for audio operation on Arndale, one of the unused I2S controllers is pinmuxed with the LDO enable GPIOs for the WM1811A. Signed-off-by: Mark Brown <broonie@xxxxxxxxxx> --- This seems like a more robust approach to handling the externally visible IPs - if this is OK I can go through and do further updates for other devices. arch/arm/boot/dts/exynos5250-arndale.dts | 4 ++++ arch/arm/boot/dts/exynos5250-smdk5250.dts | 8 -------- arch/arm/boot/dts/exynos5250.dtsi | 3 +++ 3 files changed, 7 insertions(+), 8 deletions(-) diff --git a/arch/arm/boot/dts/exynos5250-arndale.dts b/arch/arm/boot/dts/exynos5250-arndale.dts index cee55fa..4687fa0 100644 --- a/arch/arm/boot/dts/exynos5250-arndale.dts +++ b/arch/arm/boot/dts/exynos5250-arndale.dts @@ -412,6 +412,10 @@ status = "disabled"; }; + i2s0: i2s@03830000 { + status = "okay"; + }; + spi_0: spi@12d20000 { status = "disabled"; }; diff --git a/arch/arm/boot/dts/exynos5250-smdk5250.dts b/arch/arm/boot/dts/exynos5250-smdk5250.dts index 2538b32..f86d567 100644 --- a/arch/arm/boot/dts/exynos5250-smdk5250.dts +++ b/arch/arm/boot/dts/exynos5250-smdk5250.dts @@ -231,14 +231,6 @@ status = "okay"; }; - i2s1: i2s@12D60000 { - status = "disabled"; - }; - - i2s2: i2s@12D70000 { - status = "disabled"; - }; - sound { compatible = "samsung,smdk-wm8994"; diff --git a/arch/arm/boot/dts/exynos5250.dtsi b/arch/arm/boot/dts/exynos5250.dtsi index 7d7cc77..c863113 100644 --- a/arch/arm/boot/dts/exynos5250.dtsi +++ b/arch/arm/boot/dts/exynos5250.dtsi @@ -417,6 +417,7 @@ i2s0: i2s@03830000 { compatible = "samsung,s5pv210-i2s"; + status = "disabled"; reg = <0x03830000 0x100>; dmas = <&pdma0 10 &pdma0 9 @@ -433,6 +434,7 @@ i2s1: i2s@12D60000 { compatible = "samsung,s3c6410-i2s"; + status = "disabled"; reg = <0x12D60000 0x100>; dmas = <&pdma1 12 &pdma1 11>; @@ -445,6 +447,7 @@ i2s2: i2s@12D70000 { compatible = "samsung,s3c6410-i2s"; + status = "disabled"; reg = <0x12D70000 0x100>; dmas = <&pdma0 12 &pdma0 11>; -- 1.8.4.rc3 -- To unsubscribe from this list: send the line "unsubscribe linux-samsung-soc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
