This patch also adds binding file for DWMMC device node. Signed-off-by: Vivek Gautam Signed-off-by: Amar Acked-by: Jaehoon Chung Acked-by: Simon Glass --- Changes since V1: 1)Added binding file for DWMMC device node at the location "doc/device-tree-bindings/exynos/dwmmc.txt". 2)Removed the propname 'index' from device node. 3)Prefixed the vendor name 'samsung' before propname in device node. Changes since V2: 1)Updation of commit message and resubmition of proper patch set. Changes since V3: No change. Changes since V4: 1)Updated the doc/device-tree-bindings/exynos/dwmmc.txt with more information regarding the property 'samsung,timing'. 2)Replaced the name 'dwmmc' with 'mmc'. Changes since V5: 1)Added the 'removable' flag to mmc device node. arch/arm/dts/exynos5250.dtsi | 31 ++++++++++++++++++ board/samsung/dts/exynos5250-smdk5250.dts | 24 ++++++++++++++ doc/device-tree-bindings/exynos/dwmmc.txt | 54 +++++++++++++++++++++++++++++++ 3 files changed, 109 insertions(+) create mode 100644 doc/device-tree-bindings/exynos/dwmmc.txt diff --git a/arch/arm/dts/exynos5250.dtsi b/arch/arm/dts/exynos5250.dtsi index ed8c8dd..6c08eb7 100644 --- a/arch/arm/dts/exynos5250.dtsi +++ b/arch/arm/dts/exynos5250.dtsi @@ -151,4 +151,35 @@ }; }; + mmc@12200000 { + #address-cells = <1>; + #size-cells = <0>; + compatible = "samsung,exynos5250-dwmmc"; + reg = <0x12200000 0x1000>; + interrupts = <0 75 0>; + }; + + mmc@12210000 { + #address-cells = <1>; + #size-cells = <0>; + compatible = "samsung,exynos5250-dwmmc"; + reg = <0x12210000 0x1000>; + interrupts = <0 76 0>; + }; + + mmc@12220000 { + #address-cells = <1>; + #size-cells = <0>; + compatible = "samsung,exynos5250-dwmmc"; + reg = <0x12220000 0x1000>; + interrupts = <0 77 0>; + }; + + mmc@12230000 { + #address-cells = <1>; + #size-cells = <0>; + compatible = "samsung,exynos5250-dwmmc"; + reg = <0x12230000 0x1000>; + interrupts = <0 78 0>; + }; }; diff --git a/board/samsung/dts/exynos5250-smdk5250.dts b/board/samsung/dts/exynos5250-smdk5250.dts index cbfab6f..00c973a 100644 --- a/board/samsung/dts/exynos5250-smdk5250.dts +++ b/board/samsung/dts/exynos5250-smdk5250.dts @@ -30,6 +30,10 @@ spi2 = "/spi@12d40000"; spi3 = "/spi@131a0000"; spi4 = "/spi@131b0000"; + mmc0 = "/mmc@12200000"; + mmc1 = "/mmc@12210000"; + mmc2 = "/mmc@12220000"; + mmc3 = "/mmc@12230000"; }; sromc@12250000 { @@ -66,4 +70,24 @@ compatible = "maxim,max77686_pmic"; }; }; + + mmc@12200000 { + samsung,bus-width = <8>; + samsung,timing = <1 3 3>; + samsung,removable = <0>; + }; + + mmc@12210000 { + status = "disabled"; + }; + + mmc@12220000 { + samsung,bus-width = <4>; + samsung,timing = <1 2 3>; + samsung,removable = <1>; + }; + + mmc@12230000 { + status = "disabled"; + }; }; diff --git a/doc/device-tree-bindings/exynos/dwmmc.txt b/doc/device-tree-bindings/exynos/dwmmc.txt new file mode 100644 index 0000000..566da3b --- /dev/null +++ b/doc/device-tree-bindings/exynos/dwmmc.txt @@ -0,0 +1,54 @@ +* Exynos 5250 DWC_mobile_storage + +The Exynos 5250 provides DWC_mobile_storage interface which supports +.
