This patchset impacts UAPI.

The only known users of the soc-topology ABI v4 are Chromebook
configurations. Starting from kernel v5.4, all of them are making use of
soc-topology ABI v5. The patchset first removes obsolete code from the
Intel's skylake-driver - the driver of choice for the mentioned
Chromebooks - and then proceeds with removal of relevant soc-topology.c
and uapi bits.

Cezary Rojewski (4):
  ASoC: Intel: Skylake: Remove soc-topology ABI v4 support
  ASoC: topology: Remove ABI v4 support
  ASoC: topology: Cleanup after ABI v4 support removal
  ASoC: topology: Remove obsolete ABI v4 structs
