+NXP LPC18xx/43xx DMA MUX (DMA request router)
+
+Required properties:
+- compatible: "nxp,lpc1850-dmamux"
+- reg: Memory map for accessing module
+- #dma-cells: Should be set to <3>.
+ * 1st cell contain the master dma request signal
+ * 2nd cell contain the mux value (0-3) for the peripheral
+ * 3rd cell contain either 1 or 2 depending on the AHB
+ master used.
+- dma-requests: Number of DMA requests for the mux
+- dma-masters: phandle pointing to the DMA controller
+
+The DMA controller node need to have the following poroperties:
+- dma-requests: Number of DMA requests the controller can handle
+
+Example:
