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.
