| 3 | This file documents differences between the core properties in mmc.txt |
| 4 | and the properties used by the sdhci-brcmstb driver. |
| 5 | |
| 6 | NOTE: The driver disables all UHS speed modes by default and depends |
| 7 | on Device Tree properties to enable them for SoC/Board combinations |
| 8 | that support them. |

| 10 | Required properties: |
| Jaedon Shin | 5a3ab28 | 2016-09-09 11:08:39 +0900 | [diff] [blame] | 11 | - compatible: should be one of the following |
