Conceptually this seems fine.
I would have called this a "component" rather than a "chip", since:
a) That aligns better with the phrase "multi-component" for related ASoC
b) This struct doesn't always represent a whole chip, but perhaps just
an IP block within a chip. Consider an SoC with 5 completely separate
I2S block and an SPDIF block. Those are probably each separate Linux
platform devices, and each would register as its own snd_soc_chip.
To be fully useful, we'd have to convert snd_soc_sodec to be a
snd_soc_chip too. Should CODEC be a "sub-class" of chip? Should we
instead rename snd_soc_codec to snd_soc_chip/component? How do we get
there from here?
