| * 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>; |
| }; |
