From cece5656901f09db13fbb569ff04f627ec2e0ab6 Mon Sep 17 00:00:00 2001 From: Thomas Petazzoni Date: Wed, 12 Feb 2014 18:20:57 +0100 Subject: ASoC: add S/PDIF support to Armada 370 DB ASoC driver The Armada 370 DB board not only has analog audio input/output, but also S/PDIF input/output. This commit adds support for S/PDIF in the ASoC machine driver of the Armada 370 DB platform, and adjusts the Device Tree bindings documentation accordingly.

So we might get different values for them (0x4003 and 0x1003 for example): asoc-simple-card sound-cs42888.12: cpu : 2024000.esai / 4003 / 132000000 asoc-simple-card sound-cs42888.12: codec : cs42888 / 1003 / 24576000 asoc-simple-card sound-cs42888.12: cs42888 <-> 2024000.esai mapping ok This is not allowed at all as we need to keep the DAIFMT settings identical for both the ends of the link. Thus this patch fixes it by overwriting the cpu_dai->fmt with codec_dai->fmt since we defined the DAIFMT_MASTER basing on CODEC at the first place while the other bits are same.
