From: Mengdong Lin <mengdong.lin@xxxxxxxxxxxxxxx>
Here are the ABI updates for PCM (Front DAI & DAI link) objects:
- add sig_bits to stream caps.
- add flags and private data to PCM.
The kernel can handle the ABI update in a backward compatible way with
the patch "ASoC: topology: Make PCM backward compatible from ABI v4".
