Add the compatible for its SAT050AT40H12R2 5.0 inch LCD panel.
Signed-off-by: Miquel Raynal <[email protected]>
---
Changes since v4:
* Drop the satoz,sat050at40h12r2.yaml file in favor of the very new
panel-simple.yaml common file. Just add the compatible there.
Changes since v3:
* Added the missing ".yaml" suffix in the $id.
* Removed the unnecessary "contains" assertion about the compatible.
* Added a precision : there is no public specification for this panel
(known for the moment).
* Bindings checked with "make dt_binding_check"
Changes since v2:
* None.
Changes since v1:
* New patch

I'm trying to fix inconsistencies in the panel-simple driver, and this
caught my eyes. MEDIA_BUS_FMT_RGB888_1X24 isn't a correct format for
LVDS panels. MEDIA_BUS_FMT_RGB666_1X7X3_SPWG,
MEDIA_BUS_FMT_RGB888_1X7X4_SPWG or MEDIA_BUS_FMT_RGB888_1X7X4_JEIDA
should be used instead. As I couldn't find documentation for the panel,
I can't tell which format is correct. Could you please help ?

Indeed, I got this datasheet under NDA.
We checked with Paul, we think the right format is:
MEDIA_BUS_FMT_RGB888_1X7X4_SPWG.
