* Mellanox Bluefield SoC 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 Mellanox Bluefield SoC
|
|
specific extensions to the Synopsys Designware Mobile Storage Host Controller.
|
|
|
|
Required Properties:
|
|
|
|
* compatible: should be one of the following.
|
|
- "mellanox,bluefield-dw-mshc": for controllers with Mellanox Bluefield SoC
|
|
specific extensions.
|
|
|
|
Example:
|
|
|
|
/* Mellanox Bluefield SoC MMC */
|
|
mmc@6008000 {
|
|
compatible = "mellanox,bluefield-dw-mshc";
|
|
reg = <0x6008000 0x400>;
|
|
interrupts = <32>;
|
|
fifo-depth = <0x100>;
|
|
clock-frequency = <24000000>;
|
|
bus-width = <8>;
|
|
cap-mmc-highspeed;
|
|
};
