To complement panel-simple.yaml, create panel-simple-lvds-dual-ports.yaml. panel-simple-lvds-dual-ports.yaml is for all simple LVDS panels that have dual LVDS ports and require only a single power-supply. 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 'ports' property is required Suggested-by: Sam Ravnborg <sam@ravnborg.org> Cc: Thierry Reding <thierry.reding@gmail.com> Cc: Sam Ravnborg <sam@ravnborg.org> Cc: David Airlie <airlied@linux.ie> Cc: Daniel Vetter <daniel@ffwll.ch> Cc: Rob Herring <robh+dt@kernel.org> Cc: Lucas Stach <l.stach@pengutronix.de> Cc: Sebastian Reichel <sebastian.reichel@collabora.com> Signed-off-by: Liu Ying <victor.liu@nxp.com> Reviewed-by: Rob Herring <robh@kernel.org> Link: https://lore.kernel.org/r/1613017672-2734-1-git-send-email-victor.liu@nxp.com Signed-off-by: Rob Herring <robh@kernel.org>

|
|
This binding file is a collection of the LVDS panels that
|
|
has dual LVDS ports and requires only a single power-supply.
|
|
The first port receives odd pixels, and the second port receives even pixels.
|
|
There are optionally a backlight and an enable GPIO.
|
|
The panel may use an OF graph binding for the association to the display,
|
|
or it may be a direct child node of the display.
|
|
|
|
If the panel is more advanced a dedicated binding file is required.
