[PATCH v2 00/13] Add Qualcomm Nord display and eDP PHY support

From: Nabige Aala

Date: Mon Oct 12 2026 - 10:04:44 EST


Nord is a Qualcomm SoC with a DP-only display subsystem
(MDSS 12.1 / DPU 1499A) and two independent DP controllers
backed by eDP PHY. The PHY uses a different register layout,
PLL/SSC coefficients and TX signal parameters compared to
all existing SoCs supported by the qcom-edp driver.

This series enables the display pipeline on Nord by adding
DT bindings for the MDSS, DP controller and eDP PHY, DPU
catalog and driver entries for MDSS and DP, and full eDP
PHY support.

Tested on Nord Ride SX board with one DPU. Both MDSS and
DP controllers probe cleanly and panels render correctly.
