The first port receives odd pixels, and the second port receives even pixels. Optionally, a backlight and an enable GPIO can be specified as properties. Panels with swapped pixel order, if any, need dedicated bindings. Migrate 'auo,g133han01', 'auo,g185han01', 'auo,g190ean01', 'koe,tx26d202vm0bwa' and 'nlt,nl192108ac18-02d' over to the new file. The objectives with one file for all the simple LVDS panels with dual ports are: - Make it simpler to add bindings for this kind of LVDS panels - Keep the number of bindings file lower - Keep the binding documentation for this kind of LVDS panels more consistent - Make it possible for drivers to get pixel order via drm_of_lvds_get_dual_link_pixel_order(), as the optional 'ports' property is allowed Suggested-by: Sam Ravnborg Cc: Thierry Reding Cc: Sam Ravnborg Cc: David Airlie Cc: Daniel Vetter Cc: Rob Herring Cc: Lucas Stach Cc: Sebastian Reichel Signed-off-by: Liu Ying Reviewed-by: Rob Herring --- v3->v4: * Add type and descriptions for dual-lvds-{odd,even}-pixels properties.
