ASoC: pcm3168a: Allow reconfiguration of tdm_slots and slot_width (6fa4e0ca) · Commits · 戴 / test

When using right_j format and the codec is slave it can support 16bit format, but only if slot_width == 16, in the same DAI mode the 24 bit audio can work with 24 or 32 slot_width. Because of this, the codec and CPU needs to be reconfigured when the sample format changes. Signed-off-by:
