* 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;
	};
