| * Hisilicon 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 specific |
| extensions to the Synopsys Designware Mobile Storage Host Controller. |
| |
| Required Properties: |
| |
| * compatible: should be one of the following. |
| - "hisilicon,hi4511-dw-mshc": for controllers with hi4511 specific extensions. |
| - "hisilicon,hi6220-dw-mshc": for controllers with hi6220 specific extensions. |
| |
| Optional Properties: |
| - hisilicon,peripheral-syscon: phandle of syscon used to control peripheral. |
| |
