3   The eDMA channels have multiplex capability by programmble memory-mapped
4 registers. channels are split into two groups, called DMAMUX0 and DMAMUX1,
5 specific DMA request source can only be multiplexed by any channel of certain
10 - compatible :
11 	- "fsl,vf610-edma" for eDMA used similar to that on Vybrid vf610 SoC
12 	- "fsl,imx7ulp-edma" for eDMA2 used similar to that on i.mx7ulp
13 	- "fsl,ls1028a-edma" followed by "fsl,vf610-edma" for eDMA used on the
15 - reg : Specifies base physical address(s) and size of the eDMA registers.
17 	The 2nd and the 3rd regions are programmable channel multiplexing
19 - interrupts : A list of interrupt-specifiers, one for each entry in
20 	interrupt-names on vf610 similar SoC. But for i.mx7ulp per channel
21 	per transmission interrupt, total 16 channel interrupt and 1
22 	error interrupt(located in the last), no interrupt-names list on
24 - #dma-cells : Must be <2>.
30 - dma-channels : Number of channels supported by the controller
31 - clock-names : A list of channel group clock names. Should contain:
32 	"dmamux0" - clock name of mux0 group
33 	"dmamux1" - clock name of mux1 group
35 - clocks : A list of phandle and clock-specifier pairs, one for each entry in
36 	clock-names.
39 - big-endian: If present registers and hardware scatter/gather descriptors
42 - interrupt-names : Should contain the below on vf610 similar SoC but not used
44 	"edma-tx" - the transmission interrupt
45 	"edma-err" - the error interrupt
