• 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;
};
