    6 The Synopsys designware mobile storage host controller is used to interface
    7 a SoC with storage medium such as eMMC or SD/MMC cards. This file documents
    8 differences between the core Synopsys dw mshc controller properties described
    9 by synopsys-dw-mshc.txt and the properties used by the Mellanox Bluefield SoC
   10 specific extensions to the Synopsys Designware Mobile Storage Host Controller.
   11 
   12 Required Properties:
   13 
   14 * compatible: should be one of the following.
   15   - "mellanox,bluefield-dw-mshc": for controllers with Mellanox Bluefield SoC
   16     specific extensions.
   17 
   18 Example:
   19 
   20         /* Mellanox Bluefield SoC MMC */
   21         mmc@6008000 {
   22                 compatible = "mellanox,bluefield-dw-mshc";
   23                 reg = <0x6008000 0x400>;
   24                 interrupts = <32>;
   25                 fifo-depth = <0x100>;
   26                 clock-frequency = <24000000>;
   27                 bus-width = <8>;
   28                 cap-mmc-highspeed;
   29         };
