| 2 | Host Controller |
| 3 | |
| 4 | The Synopsys designware mobile storage host controller is used to interface |
| 5 | a SoC with storage medium such as eMMC or SD/MMC cards. This file documents |
| 6 | differences between the core Synopsys dw mshc controller properties described |
| 7 | by synopsys-dw-mshc.txt and the properties used by the Imagination specific |
| 8 | extensions to the Synopsys Designware Mobile Storage Host Controller. |

| 10 | Required Properties: |
| 11 | |
| 12 | * compatible: should be |
| 13 | - "img,pistachio-dw-mshc": for Pistachio SoCs |
| 14 | |
| 15 | Example: |
| 16 | |
| 17 | mmc@18142000 { |
| 18 | compatible = "img,pistachio-dw-mshc"; |
| 19 | reg = <0x18142000 0x400>; |
| 20 | interrupts = <GIC_SHARED 39 IRQ_TYPE_LEVEL_HIGH>; |
| 21 | |
| 22 | clocks = <&system_clk>, <&sdhost_clk>; |
| 23 | clock-names = "biu", "ciu"; |
| 24 | |
| 25 | fifo-depth = <0x20>; |
| 26 | bus-width = <4>; |
| 27 | num-slots = <1>; |
