1* Hisilicon specific extensions to the Synopsys Designware Mobile 2 Storage Host Controller 3 4Read synopsys-dw-mshc.txt for more details 5 6The Synopsys designware mobile storage host controller is used to interface 7a SoC with storage medium such as eMMC or SD/MMC cards. This file documents 8differences between the core Synopsys dw mshc controller properties described 9by synopsys-dw-mshc.txt and the properties used by the Hisilicon specific 10extensions to the Synopsys Designware Mobile Storage Host Controller. 11 12Required Properties: 13 14* compatible: should be one of the following. 15 - "hisilicon,hi3660-dw-mshc": for controllers with hi3660 specific extensions. 16 - "hisilicon,hi3670-dw-mshc", "hisilicon,hi3660-dw-mshc": for controllers 17 with hi3670 specific extensions. 18 - "hisilicon,hi4511-dw-mshc": for controllers with hi4511 specific extensions. 19 - "hisilicon,hi6220-dw-mshc": for controllers with hi6220 specific extensions. 20 21Optional Properties: 22- hisilicon,peripheral-syscon: phandle of syscon used to control peripheral. 23 24Example: 25 26 /* for Hi3620 */ 27 28 /* SoC portion */ 29 dwmmc_0: dwmmc0@fcd03000 { 30 compatible = "hisilicon,hi4511-dw-mshc"; 31 reg = <0xfcd03000 0x1000>; 32 interrupts = <0 16 4>; 33 #address-cells = <1>; 34 #size-cells = <0>; 35 clocks = <&mmc_clock HI3620_SD_CIUCLK>, <&clock HI3620_DDRC_PER_CLK>; 36 clock-names = "ciu", "biu"; 37 }; 38 39 /* Board portion */ 40 dwmmc0@fcd03000 { 41 vmmc-supply = <&ldo12>; 42 fifo-depth = <0x100>; 43 pinctrl-names = "default"; 44 pinctrl-0 = <&sd_pmx_pins &sd_cfg_func1 &sd_cfg_func2>; 45 bus-width = <4>; 46 disable-wp; 47 cd-gpios = <&gpio10 3 0>; 48 cap-mmc-highspeed; 49 cap-sd-highspeed; 50 }; 51 52 /* for Hi6220 */ 53 54 dwmmc_1: dwmmc1@f723e000 { 55 compatible = "hisilicon,hi6220-dw-mshc"; 56 bus-width = <0x4>; 57 disable-wp; 58 cap-sd-highspeed; 59 sd-uhs-sdr12; 60 sd-uhs-sdr25; 61 card-detect-delay = <200>; 62 hisilicon,peripheral-syscon = <&ao_ctrl>; 63 reg = <0x0 0xf723e000 0x0 0x1000>; 64 interrupts = <0x0 0x49 0x4>; 65 clocks = <&clock_sys HI6220_MMC1_CIUCLK>, <&clock_sys HI6220_MMC1_CLK>; 66 clock-names = "ciu", "biu"; 67 cd-gpios = <&gpio1 0 1>; 68 pinctrl-names = "default", "idle"; 69 pinctrl-0 = <&sd_pmx_func &sd_clk_cfg_func &sd_cfg_func>; 70 pinctrl-1 = <&sd_pmx_idle &sd_clk_cfg_idle &sd_cfg_idle>; 71 vqmmc-supply = <&ldo7>; 72 vmmc-supply = <&ldo10>; 73 }; 74
