ASoC: codec: use .auto_selectable_formats
Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> says:
This is v3 of Step2 of "use .auto_selectable_formats" patch-set
o: done
x: this patch-set
[o] Step1: ASoC: a to b
[x] Step2: ASoC: codec: ...
[ ] Step3: ASoC: d to r
[ ] Step4: ASoC: r to x
Current ASoC supports snd_soc_daifmt_parse_format() which can specify DAI
format by "dai-format" property from DT.
But strictly speaking, it is SW settings, so doesn't match to DT's policy.
Current ASoC is supporting auto format select via
snd_soc_dai_ops :: .auto_selectable_formats.
But the user is very few today.
DT doesn't need to specify the DAI format via "dai-format", if both CPU
and Codec drivers were supporting .auto_selectable_formats. It will be
automatically selected from .auto_selectable_formats.
One note is that auto select might not find best format on some CPU/Codec
combination. So "dai-format" is necessary anyway.
