From: Anusha Srivatsa <[email protected]>
Alderlake-S has 5 combo phys, add reg definitions for
combo phys and update the port to phy helper for ADL-S.
v2:
- Change IS_GEN() >= 12 to IS_TIGERLAKE() in intel_phy_is_tc()
and return false for platforms RKL,DG1 and ADLS.(mdroper)
changelog here is missing v3: fix intel_phy_is_tc breakage for DG1
but only for completeness... I remembered there was an issue in this
patch but I was not finding what it was and went to check. This one lgtm
