4 - compatible: "ti,dra7-dma-crossbar" for DRA7xx DMA crossbar
5 "ti,am335x-edma-crossbar" for AM335x and AM437x
8 for ti,dra7-dma-crossbar and <3> for ti,am335x-edma-crossbar.
9 - dma-requests: Number of DMA requests the crossbar can receive
23 When requesting channel via ti,dra7-dma-crossbar, the DMA client must request
24 the DMA event number as crossbar ID (input to the DMA crossbar).
26 For ti,am335x-edma-crossbar: the meaning of parameters of dmas for clients:
28 the event should be assigned and <1> is the mux selection for in the crossbar.
