* Imagination 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 Imagination specific
|
|
extensions to the Synopsys Designware Mobile Storage Host Controller.
|
|
|
|
Required Properties:
|
|
|
|
* compatible: should be
|
|
- "img,pistachio-dw-mshc": for Pistachio SoCs
|
|
|
|
Example:
|
|
|
|
mmc@18142000 {
|
|
compatible = "img,pistachio-dw-mshc";
|
|
reg = <0x18142000 0x400>;
|
|
interrupts = <GIC_SHARED 39 IRQ_TYPE_LEVEL_HIGH>;
|
|
|
|
clocks = <&system_clk>, <&sdhost_clk>;
|
|
clock-names = "biu", "ciu";
|
|
|
|
fifo-depth = <0x20>;
|
|
bus-width = <4>;
|
|
disable-wp;
