From d5e3237dafb91c87e0204decddd22e6378b32769 Mon Sep 17 00:00:00 2001 From: Mahadevan P Date: Mon, 20 Apr 2026 15:30:02 +0530 Subject: arm64: dts: qcom: qcs6490-rb3gen2: Enable 4-lane DisplayPort Alt Mode Add the mode-switch property to the QMP combo PHY so that mode-switch events are routed to it, allowing the PHY to enter DisplayPort Alternate Mode. Expand the DP data-lanes assignment from two to four lanes to make use of the full link bandwidth available in this configuration.
