Introduce "altr,socfpga-dw-mshc" to enable Altera's SOCFPGA platform specific implementation of the dw_mmc driver. Also add the "syscon" binding to the "altr,sys-mgr" node. The clock driver can use the syscon driver to toggle the register for the SD/MMC clock phase shift settings. Finally, fix an indentation error for the sysmgr node.

* Altera SOCFPGA specific extensions to the Synopsys Designware Mobile
|
|
Storage Host Controller
|
|
|
|
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 Altera SOCFPGA specific
|
|
extensions to the Synopsys Designware Mobile Storage Host Controller.
|
|
|
|
Required Properties:
|
|
|
|
* compatible: should be
|
|
- "altr,socfpga-dw-mshc": for Altera's SOCFPGA platform
|
|
|
|
Example:
|
|
|
|
mmc: dwmmc0@ff704000 {
|
|
compatible = "altr,socfpga-dw-mshc";
|
|
reg = <0xff704000 0x1000>;
|
|
interrupts = <0 129 4>;
|
|
#address-cells = <1>;
|
|
#size-cells = <0>;
|
|
};
