From 1703470aa7cfbef8d8e596106447bac894f5623e Mon Sep 17 00:00:00 2001 From: Russell King Date: Tue, 20 Nov 2012 12:20:55 +0000 Subject: [PATCH] ASoC: kirkwood-dma: remove channel restrictions This is part of a patch found in Rabeeh Khoury's git tree for the cubox. With SPDIF passthrough, we are not restricted to just two channels of audio; we can support however many channels the non-audio stream can itself support. In any case, kirkwood-dma is not involved in the format selection. So yet rid of this restriction.
