| 3 | The MMC Host Controller on TI OMAP1 and 2420 family provides |
| 4 | an interface for MMC, SD, and SDIO types of memory cards. |

| 6 | This file documents differences between the core properties described |
| 7 | by mmc.txt and the properties used by the omap mmc driver. |

| 9 | Note that this driver will not work with omap2430 or later omaps, |
| 10 | please see the omap hsmmc driver for the current omaps. |

| 12 | Required properties: |
| 13 | - compatible: Must be "ti,omap2420-mmc", for OMAP2420 controllers |
| 14 | - ti,hwmods: For 2420, must be "msdi<n>", where n is controller |
| 15 | instance starting 1 |

| 19 | msdi1: mmc@4809c000 { |
| 20 | compatible = "ti,omap2420-mmc"; |
| 21 | ti,hwmods = "msdi1"; |
| 22 | reg = <0x4809c000 0x80>; |
| 23 | interrupts = <83>; |
