-* TI MMC host controller for OMAP1 and 2420
-
-The MMC Host Controller on TI OMAP1 and 2420 family provides
-an interface for MMC, SD, and SDIO types of memory cards.
-
-This file documents differences between the core properties described
-by mmc.txt and the properties used by the omap mmc driver.
-
-Note that this driver will not work with omap2430 or later omaps,
-please see the omap hsmmc driver for the current omaps.
-
-Required properties:
-- compatible: Must be "ti,omap2420-mmc", for OMAP2420 controllers
-- ti,hwmods: For 2420, must be "msdi<n>", where n is controller
-  instance starting 1
-
-Examples:
-
-	msdi1: mmc@4809c000 {
-		compatible = "ti,omap2420-mmc";
-		ti,hwmods = "msdi1";
-		reg = <0x4809c000 0x80>;
-		interrupts = <83>;
-		dmas = <&sdma 61 &sdma 62>;
-		dma-names = "tx", "rx";
-	};
