Add MMC controller support for HiSilicon HI3670 SoC reusing the HI3660 Designware MMC driver. There are 2 DWMMC controllers present in this SoC:
1. DWMMC1 is used for SD card (SD) 2. DWMMC2 is used for WiFi (SDIO) Signed-off-by: Manivannan Sadhasivam <[email protected]> --- arch/arm64/boot/dts/hisilicon/hi3670.dtsi | 37 +++++++++++++++++++++++ 1 file changed, 37 insertions(+) diff --git a/arch/arm64/boot/dts/hisilicon/hi3670.dtsi b/arch/arm64/boot/dts/hisilicon/hi3670.dtsi index 9864cf59ebd8..080d6ba5ae39 100644 --- a/arch/arm64/boot/dts/hisilicon/hi3670.dtsi +++ b/arch/arm64/boot/dts/hisilicon/hi3670.dtsi @@ -671,5 +671,42 @@ resets = <&crg_rst 0x84 12>; reset-names = "rst"; }; + + /* SD */ + dwmmc1: dwmmc1@ff37f000 { + compatible = "hisilicon,hi3670-dw-mshc", + "hisilicon,hi3660-dw-mshc"; + reg = <0x0 0xff37f000 0x0 0x1000>; + #address-cells = <1>; + #size-cells = <0>; + interrupts = <GIC_SPI 139 IRQ_TYPE_LEVEL_HIGH>; + clocks = <&crg_ctrl HI3670_CLK_GATE_SD>, + <&crg_ctrl HI3670_HCLK_GATE_SD>; + clock-names = "ciu", "biu"; + clock-frequency = <3200000>; + resets = <&crg_rst 0x94 18>; + reset-names = "reset"; + hisilicon,peripheral-syscon = <&sctrl>; + card-detect-delay = <200>; + status = "disabled"; + }; + + /* SDIO */ + dwmmc2: dwmmc2@fc183000 { + compatible = "hisilicon,hi3670-dw-mshc", + "hisilicon,hi3660-dw-mshc"; + reg = <0x0 0xfc183000 0x0 0x1000>; + #address-cells = <1>; + #size-cells = <0>; + interrupts = <GIC_SPI 140 IRQ_TYPE_LEVEL_HIGH>; + clocks = <&crg_ctrl HI3670_CLK_GATE_SDIO>, + <&crg_ctrl HI3670_HCLK_GATE_SDIO>; + clock-names = "ciu", "biu"; + clock-frequency = <3200000>; + resets = <&crg_rst 0x94 20>; + reset-names = "reset"; + card-detect-delay = <200>; + status = "disabled"; + }; }; }; -- 2.17.1
