* 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 extentions.
|
||
|
|
||
|
Example:
|
||
|
|
||
|
/* for Hi3620 */
|
||
|
|
||
|
/* SoC portion */
|
||
|
