Intel platform will configure the SerDes through PMC api based on the
provided interface mode.
This patch adds several new functions below:-
- intel_tsn_interface_is_available(): This new function reads FIA lane
ownership registers and common lane registers through IPC commands
to know which lane the mGbE port is assigned to.
- intel_config_serdes(): To configure the SerDes based on the assigned
lane and latest interface mode, it sends IPC command to the PMC through
PMC driver/API. The PMC acts as a proxy for R/W on behalf of the driver.
- intel_set_reg_access(): Set the register access to the available TSN
interface.

INTEL_PMC_IPC has depends on ACPI but selecting INTEL_PMC_IPC won't

Hi Ilpo,
Thank you for pointing this out.
I will check on my side too.
Will fix it in the new patch series.
