* Hisilicon Hi3798CV200 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 Hi3798CV200 specific extensions to the Synopsys Designware Mobile Storage Host Controller. Required Properties: - compatible: Should contain "hisilicon,hi3798cv200-dw-mshc". - clocks: A list of phandle + clock-specifier pairs for the clocks listed in clock-names. - clock-names: Should contain the following: "ciu" - The ciu clock described in synopsys-dw-mshc.txt. "biu" - The biu clock described in synopsys-dw-mshc.txt. "ciu-sample" - Hi3798CV200 extended phase clock for ciu sampling. "ciu-drive" - Hi3798CV200 extended phase clock for ciu driving. Example: emmc: mmc@9830000 { compatible = "hisilicon,hi3798cv200-dw-mshc"; reg = <0x9830000 0x10000>; interrupts = <GIC_SPI 35 IRQ_TYPE_LEVEL_HIGH>; clocks = <&crg HISTB_MMC_CIU_CLK>, <&crg HISTB_MMC_BIU_CLK>, <&crg HISTB_MMC_SAMPLE_CLK>, <&crg HISTB_MMC_DRV_CLK>; clock-names = "ciu", "biu", "ciu-sample", "ciu-drive"; fifo-depth = <256>; clock-frequency = <200000000>; cap-mmc-highspeed; mmc-ddr-1_8v; mmc-hs200-1_8v; non-removable; bus-width = <8>; }; |
