Merge series "ASoC: pcm512x: Patch series to set fmt from `set_fmt()`" from Kirill Marinushkin <kmarinushkin@birdec.com>:

Set format from `set_fmt()` func instead of `hw_params()`, plus supportive
commits

Kirill Marinushkin (4):
  ASoC: pcm512x: Fix not setting word length if DAIFMT_CBS_CFS
  ASoC: pcm512x: Rearrange operations in `hw_params()`
  ASoC: pcm512x: Move format check into `set_fmt()`
  ASoC: pcm512x: Add support for more data formats
