[PATCH v1 0/3] Add eDP lane mapping support

[Damon Ding]

This patch series is followed by:
https://lore.kernel.org/all/20260513074414.2053435-1-damon.ding@rock-chips.com/

This series adds configurable eDP/DP physical lane mapping support
via device tree data-lanes property.

Lane mapping is mainly used for below scenarios:
1. Correct PCB lane swap and differential line routing crossover
   without hardware changes;
2. Adapt mismatched lane pin definitions between SoC and eDP panel;
3. Support multiple panel hardware variants on the same board
   by configuring data-lanes in device tree only.

The series includes driver implementation and device tree binding
updates to support custom lane mapping configuration from endpoint
node, and keeps default linear lane order if no configuration is given.

Patch 1: Supplement inherited properties for rockchip,analogix-dp schema
Patch 2: Add endpoint data-lanes property to analogix-dp binding
Patch 3: Implement lane mapping in analogix_dp driver

  dt-bindings: display: rockchip: analogix-dp: Expose inherited
    properties
  dt-bindings: display: bridge: analogix-dp: Add data-lanes support for
    endpoint
  drm/bridge: analogix_dp: Add support for optional data-lanes mapping
