[alsa-devel] asoc multi-component: almost there!

[Timur Tabi]

Liam,

I almost got it working.  I can generate names that match, so it finds it:

soc_bind_dai_link:1136 cpu_dai->name=e0016000.ssi,
dai_link->cpu_dai_name=e0016000.ssi
soc_bind_dai_link:1159 codec->name=cs4270-codec.0-004f,
dai_link->codec_name=cs4270-codec.0-004f
soc_bind_dai_link:1169 codec_dai->name=e0016000.ssi,
dai_link->codec_dai_name=cs4270-hifi
soc_bind_dai_link:1169 codec_dai->name=cs4270-hifi,
dai_link->codec_dai_name=cs4270-hifi
soc_bind_dai_link:1194 platform->name=e0021180.dma-channel,
dai_link->platform_name=e0021100.dma-channel
soc_bind_dai_link:1194 platform->name=e0021100.dma-channel,
dai_link->platform_name=e0021100.dma-channel
soc_bind_dai_link:1136 cpu_dai->name=e0016000.ssi,
dai_link->cpu_dai_name=e0016000.ssi
soc_bind_dai_link:1159 codec->name=cs4270-codec.0-004f,
dai_link->codec_name=cs4270-codec.0-004f
soc_bind_dai_link:1169 codec_dai->name=e0016000.ssi,
dai_link->codec_dai_name=cs4270-hifi
soc_bind_dai_link:1169 codec_dai->name=cs4270-hifi,
dai_link->codec_dai_name=cs4270-hifi
soc_bind_dai_link:1194 platform->name=e0021180.dma-channel,
dai_link->platform_name=e0021180.dma-channel
asoc: cs4270-hifi <-> e0016000.ssi mapping ok

but then I get this:

sysfs: cannot create duplicate filename '/devices/platform/soc-audio/cs4270'

I'm registering two DAIs -- one for playback, one for capture, but I'm
using the same name for the codec DAI.  How do I resolve this?
