| 1 | * TI MMC host controller for OMAP1 and 2420 | ||
| 2 | |||
| 3 | The MMC Host Controller on TI OMAP1 and 2420 family provides | ||
| 4 | an interface for MMC, SD, and SDIO types of memory cards. | ||
| 5 | |||
| 6 | This file documents differences between the core properties described | ||
| 7 | by mmc.txt and the properties used by the omap mmc driver. | ||
| 8 | |||
| 9 | Note that this driver will not work with omap2430 or later omaps, | ||
| 10 | please see the omap hsmmc driver for the current omaps. | ||
| 11 | |||
| 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 | ||
| 16 | |||
| 17 | Examples: | ||
| 18 | |||
| 19 | msdi1: mmc@4809c000 { | ||
| 20 | compatible = "ti,omap2420-mmc"; | ||
| 21 | ti,hwmods = "msdi1"; | ||
