Subject: [PATCH] dt-bindings: display: Reorganize legacy eDP panel bindings
Back in the day, we used to need to list the exact panel in dts for
eDP panels. This led to all sorts of problems including a large number
of cases where people listed a bogus panel in their device tree
because of the needs of second sourcing (and third sourcing, and
fourth sourcing, ...). Back when we needed to add eDP panels to dts
files we used to list them in "panel-simple.yaml".
These days we have the new way of doing things as documented in
"panel-edp.yaml". We can just list the compatible "edp-panel", add
some timing info to the source code, and we're good to go. There's not
really good reasons not to use this new method.
To try to make it obvious that we shouldn't add new compatible strings
for eDP panels, let's move them all out of the old "panel-simple.yaml"
file to their own file: "panel-edp-legacy.yaml". This new file will
have a description that makes it obvious that we shouldn't use it for
new panels.
While we're doing this:
- We can remove eDP-specific properties from panel-simple.yaml since
there are no more panels there.
- We don't need to copy non-eDP properties to the
"panel-edp-legacy.yaml".
- We'll fork off a separate yaml file for "samsung,atna33xc20.yaml".
This is an eDP panel which isn't _quite_ handled by the generic
"edp-panel" compatible since it's not allowed to have an external
backlight (it has one builtin) and it absolutely requires an
"enable" GPIO.
- We'll un-fork the "sharp,ld-d5116z01b.yaml" and put it in
"panel-edp-legacy.yaml" since there doesn't appear to be any reason
for it to be separate.

+title: Legacy eDP panels from before the "edp-panel" compatible

+description: |
+ This binding file is a collection of eDP panels from before the generic
+ "edp-panel" compatible was introduced. It is kept around to support old
+ dts files. The only reason one might add a new panel here instead of using
+ the generic "edp-panel" is if it needed to be used on an eDP controller
+ that doesn't support the generic "edp-panel" compatible, but it should be
+ a strong preference to add the generic "edp-panel" compatible instead.
