Optional TX & RX dma specifiers. Each specifier will have a phandle
|
|
reference to the dmac controller, the channel number, and peripheral
|
|
trigger source.
|
|
|
|
For example dmas for TX, RX on SERCOM3
|
|
dmas = <&dmac 0 0xb>, <&dmac 1 0xa>;
|
|
|
|
dma-names:
|
|
description: |
|
|
Required if the dmas property exists. This should be "tx" and "rx"
|
|
to match the dmas property.
|
|
|
|
For example
|
|
dma-names = "tx", "rx";
