Subject: phy: qcom: qmp-combo: fix VCO div offset on v5_5nm and v6
From: Johan Hovold <johan+linaro@xxxxxxxxxx>
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.
