Subject[PATCH v4 1/3] dt-bindings: one file of all simple DSI panels
Date
From: Sam Ravnborg <sam@ravnborg.org>

To complement panel-simple.yaml, create panel-simple-dsi.yaml.
panel-simple-dsi-yaml are for all simple DSP panels with a single
power-supply and optional backlight / enable GPIO.

Migrate panasonic,vvx10f034n00 over to the new file.

The objectives with one file for all the simple DSI panels are:
- Make it simpler to add bindings for simple DSI panels
- Keep the number of bindings file lower
- Keep the binding documentation for simple DSI panels more consistent

+
+description: |
+ This binding file is a collection of the DSI panels that
+ requires only a single power-supply.
+ 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.
