+title: Phytium DDMA Controller bindings
+
+description:
+The Phytium DDMA is a general-purpose direct memory access
+controller capable of supporting 8 independent DMA channels.
+Each channel can have up to 32 requests.DMA clients connected
+to the Phytium DDMA controller must use the format described
+in the dma.txt file, using a two-cell specifier for each
+channel:
+  a phandle to the DMA controller plus the following two integer cells:
+    1. The channel id
+    2. The request line number
