[PATCH 0/2] phy: qcom: edp: Update v8 programming sequence

From: Bjorn Andersson

Date: Mon Jun 22 2026 - 19:30:12 EST


The programming sequences introduced for v8 doesn't work other than for
4-lane 8.1Gbps. For 2-lane 5.4Gbps link training fails and for 2.7 and
1.62Gbps PLL lock isn't reached.

Update the driver to match the documentation (and Windows driver for the
1.62Gbps PLL settings), to get past the link training on lower
resolution monitors.
