1 | * Hisilicon specific extensions to the Synopsys Designware Mobile |
| 2 | Storage Host Controller | |
| 3 | ||
| 4 | Read synopsys-dw-mshc.txt for more details | |
| 5 | ||
| 6 | The Synopsys designware mobile storage host controller is used to interface | |
| 7 | a SoC with storage medium such as eMMC or SD/MMC cards. This file documents | |
| 8 | differences between the core Synopsys dw mshc controller properties described | |
| 9 | by synopsys-dw-mshc.txt and the properties used by the Hisilicon specific | |
| 10 | extensions to the Synopsys Designware Mobile Storage Host Controller. | |
| 11 | ||
| 12 | Required Properties: | |
| 13 | ||
| 14 | * compatible: should be one of the following. | |
| 15 | - "hisilicon,hi4511-dw-mshc": for controllers with hi4511 specific extentions. | |
