Document the devicetree bindings for Socionext Milbeaut HDMAC
controller. Controller has upto 8 floating channels, that need
a predefined slave-id to work from a set of slaves.

+* Milbeaut AHB DMA Controller
+
+Milbeaut AHB DMA controller has transfer capability below.
+ - device to memory transfer
+ - memory to device transfer
+
+Required property:
+- compatible:       Should be  "socionext,milbeaut-m10v-hdmac"
+- reg:              Should contain DMA registers location and length.
+- interrupts:       Should contain all of the per-channel DMA interrupts.
+                     Number of channels is configurable - 2, 4 or 8, so
+                     the number of interrupts specified should be {2,4,8}.
+- #dma-cells:       Should be 1. Specify the ID of the slave.
+- clocks:           Phandle to the clock used by the HDMAC module.
+
+
+Example:
+
+       hdmac1: dma-controller@1e110000 {
+               compatible = "socionext,milbeaut-m10v-hdmac";
+               reg = <0x1e110000 0x10000>;
+               interrupts = <0 132 4>,
+                            <0 133 4>,
+                            <0 134 4>,
+                            <0 135 4>,
+                            <0 136 4>,
+                            <0 137 4>,
+                            <0 138 4>,
+                            <0 139 4>;
+               #dma-cells = <1>;
+               clocks = <&dummy_clk>;
+       };
