| * ZTE specific extensions to the Synopsys Designware Mobile Storage |
| Host Controller |
| |
| 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 ZTE specific |
| extensions to the Synopsys Designware Mobile Storage Host Controller. |
| |
| Required Properties: |
| |
| * compatible: should be |
| - "zte,zx296718-dw-mshc": for ZX SoCs |
| |
| Example: |
| |
| mmc1: mmc@1110000 { |
| compatible = "zte,zx296718-dw-mshc"; |
| reg = <0x01110000 0x1000>; |
| interrupts = <GIC_SPI 15 IRQ_TYPE_LEVEL_HIGH>; |
| fifo-depth = <32>; |
| data-addr = <0x200>; |
| fifo-watermark-aligned; |
| bus-width = <4>; |
| clock-frequency = <50000000>; |
| clocks = <&topcrm SD0_AHB>, <&topcrm SD0_WCLK>; |
| clock-names = "biu", "ciu"; |
| max-frequency = <50000000>; |
| cap-sdio-irq; |
| cap-sd-highspeed; |
| }; |
