commit 025a6f7448f7bb5f4fceb62498ee33d89ae266bb upstream.
Commit 5abed58a8bde ("phy: qcom: qmp-combo: Fix VCO div offset on v3") fixed a regression introduced in 6.5 by making sure that the correct offset is used for the DP_PHY_VCO_DIV register on v3 hardware.
Unfortunately, that fix instead broke DisplayPort on v5_5nm and v6 hardware as it failed to add the corresponding offsets also to those register tables.
