Hi Anil/Team,

Can someone will explain me the dma entries property in linux device tree.

dmas = <&edma 16 0 ( what are these number 16 0) ?
&edma 17 0
&edma 18 0
&edma 19 0>;
dma-names = "tx0", "rx0", "tx1", "rx1" (?)

I am not able to recollect this learning part.

Regards,
Rajat Bandha

If it is generic ones, check then out in the corresponding file(s) under Documentation/devicetree/bindings in the kernel source.
