+TI SDMA
+
+Required Properties:
+- compatible : Should be "ti,omap2420-sdma", "ti,omap2430-sdma" for OMAP2
+ Should be "ti,omap3430-sdma", "ti,omap3630-sdma" for OMAP3
+ Should be "ti,omap4430-sdma" for OMAP4, OMAP5 and DRA7
+- reg: Memory map for accessing module
+- interrupts: Interrupt request number from the dma controller to
+ interrupt controller
+- dma-cells: Should be set to <1>
+- dma-channels: Total number of logical DMA channels supported by the
+ controller
+- dma-requests: Total number of dma request signals supported by the
+ controller
+
+Example:
+
+sdma: dma-controller@48056000 {
+ compatible = "ti,omap4430-sdma";
+ reg = <0x48056000 0x1000>;
+ interrupts = <12>,
+ <13>,
+ <14>,
+ <15>;
+ #dma-cells = <1>;
+ #dma-channels = <32>;
+ #dma-requests = <64>;
