Deprecate the adi,channels node in the adi,axi-dmac binding. Prior to IP version 4.3.a, this information was required. Since then, there are memory-mapped registers that can be read to get the same information. Acked-by: Nuno Sa <nuno.sa@xxxxxxxxxx> Signed-off-by: David Lechner <dlechner@xxxxxxxxxxxx> --- For context, the adi,channels node has not been required in the Linux kernel since [1].
