Subject: [PATCH] ASoC: pcm3168a: Allow reconfiguration of tdm_slots and slot_width
Git-commit: 6fa4e0cae684d268d309d1b1f929d52e3df5649c
Patch-mainline: v5.4-rc1
References: jsc#SLE-16518

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.
