* 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,hi3660-dw-mshc": for controllers with hi3660 specific extensions. |
|
- "hisilicon,hi3670-dw-mshc", "hisilicon,hi3660-dw-mshc": for controllers |
|
with hi3670 specific extensions. |
|
- "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. |
|
|
|

|
|
|
/* for Hi3620 */ |
