Add support for the LG LP156WF1 15.6" Full-HD dual-link LVDS panel and
a Verdin AM62 overlay for using it through the Verdin Development Board
with the Verdin AM62 Mezzanine LVDS interface.
This is a follow-up to an earlier attempt [1], where panel-lvds.yaml
was incorrectly extended to describe dual-link panels. Back in 2023,
when a generic dual-channel LVDS binding was proposed, Rob Herring [2]
pointed out that dual-link panels should follow the existing
advantech,idk-2121wr pattern instead of introducing a new generic
compatible.
Following that approach, this series adds a dedicated binding for
lg,lp156wf1, with the dual-link LVDS ports described by
lvds-dual-ports.yaml, and excludes it from the generic panel-lvds
schema selection.
The second patch adds the Verdin AM62 overlay for the LG LP156WF1 panel
on the Mezzanine LVDS connector.
This series should be applied on top of [3] to avoid conflicts in the TI
device-tree Makefile with the other overlay additions.
