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?
