* ZTE 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 ZTE specific

extensions to the Synopsys Designware Mobile Storage Host Controller.



Required Properties:



* compatible: should be

	- "zte,zx296718-dw-mshc": for ZX SoCs



Example:



	mmc1: mmc@1110000 {

		compatible = "zte,zx296718-dw-mshc";

		reg = <0x01110000 0x1000>;

		interrupts = <GIC_SPI 15 IRQ_TYPE_LEVEL_HIGH>;

		fifo-depth = <32>;

		data-addr = <0x200>;

		fifo-watermark-aligned;

		bus-width = <4>;

		clock-frequency = <50000000>;

		clocks = <&topcrm SD0_AHB>, <&topcrm SD0_WCLK>;

		clock-names = "biu", "ciu";

		num-slots = <1>;

		max-frequency = <50000000>;

		cap-sdio-irq;

		cap-sd-highspeed;

		status = "disabled";
