+
+ Inherits from mmc binding[1].
+
+ [1] Documentation/devicetree/bindings/mmc/mmc.txt
+
+Required properties:
+
+- compatible : Must be "moxa,moxart-mmc" or "faraday,ftsdc010"
+- reg : Should contain registers location and length
+- interrupts : Should contain the interrupt number
+- clocks : Should contain phandle for the clock feeding the MMC controller
+
+Optional properties:
+
+- dmas : Should contain two DMA channels, line request number must be 5 for
+ both channels
+- dma-names : Must be "tx", "rx"
+
+Example:
+
+ mmc: mmc@98e00000 {
+ compatible = "moxa,moxart-mmc";
+ reg = <0x98e00000 0x5C>;
+ interrupts = <5 0>;
+ clocks = <&clk_apb>;
+ dmas = <&dma 5>,
+ <&dma 5>;
+ dma-names = "tx", "rx";
+ };
