[PATCH v4 0/7] drm/sun4i: Add support for dual-link LVDS on the A20

[Maxime Ripard <maxime@cerno.tech>]

Hi,

This is a fourth attempt at supporting the LVDS dual-link output on the
Allwinner A20.

Let me know what you think,
Maxime

Changes from v3:
  - Reintroduce the endpoint sanity check (and make of_graph_get_port_by_id
    const in the process)
  - Make a few doc fixes
  - Fix device_node leakage
  - Changed allwinner,lvds-companion to more generic link-companion
  - Rebased on 5.11

Changes from v2:
  - Added the DT binding description
  - Split the patch to enable the A20
  - Reworked a bit the error messages

Changes from v1:
  - Reworked the DT bindings
  - Refactored a bit the panel registration in the tcon code.

Maxime Ripard (7):
  of: Make of_graph_get_port_by_id take a const device_node
  drm/of: Change the prototype of drm_of_lvds_get_dual_link_pixel_order
  dt-bindings: display: sun4i: Add LVDS Dual-Link property
  drm/sun4i: tcon: Refactor the LVDS and panel probing
  drm/sun4i: tcon: Support the LVDS Dual-Link
