From: Dinh Nguyen <dinguyen@xxxxxxxxxx> Use the "snps,dw-mshc" binding to enable the dw_mmc driver. Add the "syscon" binding to the "altr,sys-mgr" node. The clock driver can use the syscon driver to toggle the register for the SD/MMC clock phase shift settings. Signed-off-by: Dinh Nguyen <dinguyen@xxxxxxxxxx> --- v8: none v7: Use the standard "snps,dw-mshc" binding. Remove "altr,socfpga-sdmmc-sdr-clk". v6: Add documentation for "altr,socfpga-sdmmc-sdr-clk". Add "syscon" to the sysmgr binding. v5: Use the "snps,dw-mshc" binding v4: Re-use "rockchip,rk2928-dw-mshc" binding v3: none v2: none --- arch/arm/boot/dts/socfpga.dtsi | 13 ++++++++++++- arch/arm/boot/dts/socfpga_arria5.dtsi | 11 +++++++++++ arch/arm/boot/dts/socfpga_cyclone5.dtsi | 11 +++++++++++ arch/arm/boot/dts/socfpga_vt.dts | 11 +++++++++++ 4 files changed, 45 insertions(+), 1 deletion(-) diff --git a/arch/arm/boot/dts/socfpga.dtsi b/arch/arm/boot/dts/socfpga.dtsi index e776512..433bfbc 100644 --- a/arch/arm/boot/dts/socfpga.dtsi +++ b/arch/arm/boot/dts/socfpga.dtsi @@ -470,6 +470,17 @@ cache-level = <2>; }; + mmc: dwmmc0@ff704000 { + compatible = "snps,dw-mshc"; + reg = <0xff704000 0x1000>; + interrupts = <0 139 4>; + fifo-depth = <0x400>; + #address-cells = <1>; + #size-cells = <0>; + clocks = <&l4_mp_clk>, <&sdmmc_clk>; + clock-names = "biu", "ciu"; + }; + /* Local timer */ timer@fffec600 { compatible = "arm,cortex-a9-twd-timer"; @@ -524,7 +535,7 @@ }; sysmgr@ffd08000 { - compatible = "altr,sys-mgr"; + compatible = "altr,sys-mgr", "syscon"; reg = <0xffd08000 0x4000>; }; }; diff --git a/arch/arm/boot/dts/socfpga_arria5.dtsi b/arch/arm/boot/dts/socfpga_arria5.dtsi index a85b404..6c87b70 100644 --- a/arch/arm/boot/dts/socfpga_arria5.dtsi +++ b/arch/arm/boot/dts/socfpga_arria5.dtsi @@ -27,6 +27,17 @@ }; }; + dwmmc0@ff704000 { + num-slots = <1>; + supports-highspeed; + broken-cd; + + slot@0 { + reg = <0>; + bus-width = <4>; + }; + }; + serial0@ffc02000 { clock-frequency = <100000000>; }; diff --git a/arch/arm/boot/dts/socfpga_cyclone5.dtsi b/arch/arm/boot/dts/socfpga_cyclone5.dtsi index a8716f6..ca41b0e 100644 --- a/arch/arm/boot/dts/socfpga_cyclone5.dtsi +++ b/arch/arm/boot/dts/socfpga_cyclone5.dtsi @@ -28,6 +28,17 @@ }; }; + dwmmc0@ff704000 { + num-slots = <1>; + supports-highspeed; + broken-cd; + + slot@0 { + reg = <0>; + bus-width = <4>; + }; + }; + ethernet@ff702000 { phy-mode = "rgmii"; phy-addr = <0xffffffff>; /* probe for phy addr */ diff --git a/arch/arm/boot/dts/socfpga_vt.dts b/arch/arm/boot/dts/socfpga_vt.dts index d1ec0ca..222313f 100644 --- a/arch/arm/boot/dts/socfpga_vt.dts +++ b/arch/arm/boot/dts/socfpga_vt.dts @@ -41,6 +41,17 @@ }; }; + dwmmc0@ff704000 { + num-slots = <1>; + supports-highspeed; + broken-cd; + + slot@0 { + reg = <0>; + bus-width = <4>; + }; + }; + ethernet@ff700000 { phy-mode = "gmii"; status = "okay"; -- 1.7.9.5 -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
