It is not direct related to this patch - but you touch the file...
This binding should require a specific + a generic binding.
So any panel that in the beginng can fallback only on the generic
handling can later fallback to some panel specific quirks.
This is easy to express in .yaml format like this:
properties:
compatible:
description:
Shall contain a panel specific compatible and "panel-dps-cm"
in that order.
items:
- {}
- const: panel-dsi-cm
This will not prevent a user from using:
compatible: "foo,bar","panel-dsi-cm"
But then there is documentation for a specific compatible.
On top of this - no changes to .txt files in panel/
You need to convert to DT Schema and then patch the binding.
(Not a global fixed rule - but something I try to enforce to get the
rest converted).
