* 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.
|
|
|
|

|
|
|
|
/* for Hi3620 */
