| 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; |
