+* TI Highspeed MMC host controller for DaVinci
+
+The Highspeed MMC Host Controller on TI DaVinci family
+provides an interface for MMC, SD and SDIO types of memory cards.
+
+This file documents the properties used by the davinci_mmc driver.
+
+Required properties:
+- compatible:
+ Should be "ti,da830-mmc": for da830, da850, dm365
+ Should be "ti,dm355-mmc": for dm355, dm644x
+
+Optional properties:
+- bus-width: Number of data lines, can be <1>, <4>, or <8>, default <1>
+- max-frequency: Maximum operating clock frequency, default 25MHz.
+- dmas: List of DMA specifiers with the controller specific format
+ as described in the generic DMA client binding. A tx and rx
+ specifier is required.
+- dma-names: RX and TX DMA request names. These strings correspond
+ 1:1 with the DMA specifiers listed in dmas.
+
+Example:
+mmc0: mmc@1c40000 {
+ compatible = "ti,da830-mmc",
+ reg = <0x40000 0x1000>;
+ interrupts = <16>;
+ bus-width = <4>;
+ max-frequency = <50000000>;
+ dmas = <&edma 16
+ &edma 17>;
+ dma-names = "rx", "tx";
+};
