* Hisilicon specific extensions to the Synopsys Designware Mobile Storage Host Controller Read synopsys-dw-mshc.txt for more details The Synopsys designware mobile storage host controller is used to interface a SoC with storage medium such as eMMC or SD/MMC cards. This file documents differences between the core Synopsys dw mshc controller properties described by synopsys-dw-mshc.txt and the properties used by the Hisilicon specific extensions to the Synopsys Designware Mobile Storage Host Controller. Required Properties: * compatible: should be one of the following. - "hisilicon,hi4511-dw-mshc": for controllers with hi4511 specific extensions. Example: /* for Hi3620 */ /* SoC portion */ dwmmc_0: dwmmc0@fcd03000 { compatible = "hisilicon,hi4511-dw-mshc"; reg = <0xfcd03000 0x1000>; interrupts = <0 16 4>; #address-cells = <1>; #size-cells = <0>; clocks = <&mmc_clock HI3620_SD_CIUCLK>, <&clock HI3620_DDRC_PER_CLK>; clock-names = "ciu", "biu"; }; /* Board portion */ dwmmc0@fcd03000 { num-slots = <1>; vmmc-supply = <&ldo12>; fifo-depth = <0x100>; pinctrl-names = "default"; pinctrl-0 = <&sd_pmx_pins &sd_cfg_func1 &sd_cfg_func2>; bus-width = <4>; disable-wp; cd-gpios = <&gpio10 3 0>; cap-mmc-highspeed; cap-sd-highspeed; };
