[PATCH v4 0/3] dt-bindings: add simple DSI panels

[PATCH v4 0/3] dt-bindings: add simple DSI panels

[Benjamin Gaignard]

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 / reset GPIO.

Some DSI panels like orisetech,otm8009a or raydium,rm68200 are quite
similar to simple dsi panel but with small variations. Create dedicated
yaml files for them.

  dt-bindings: panel: Convert orisetech,otm8009a to json-schema

[PATCH v4 1/3] dt-bindings: one file of all simple DSI panels

[Benjamin Gaignard]

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

version 4:
- remove orisetech,otm8009a and raydium,rm68200 compatibles
- remove reset-gpios optional property

version 3:
- add orisetech,otm8009a and raydium,rm68200 compatibles
- add reset-gpios optional property
- fix indentation on compatible enumeration
