* 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>;
num-slots = <1>;
disable-wp;
};
