From: Sam Ravnborg <redacted>

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.

Migrate panasonic,vvx10f034n00, orisetech,otm8009a and raydium,rm68200 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 3:
- add orisetech,otm8009a and raydium,rm68200 compatibles
- add reset-gpios optional property
- fix indentation on compatible enumeration
=> Rob had reviewed the second version but, given the changes in version 3
   I haven't added here.

-Orise Tech OTM8009A 3.97" 480x800 TFT LCD panel (MIPI-DSI video mode)
-
-The Orise Tech OTM8009A is a 3.97" 480x800 TFT LCD panel connected using
-a MIPI-DSI video interface. Its backlight is managed through the DSI link.
-
-Required properties:
-  - compatible: "orisetech,otm8009a"
-  - reg: the virtual channel number of a DSI peripheral
-
-Optional properties:
-  - reset-gpios: a GPIO spec for the reset pin (active low).
-  - power-supply: phandle of the regulator that provides the supply voltage.
-
-Example:
-&dsi {
-       ...
-       panel@0 {
-               compatible = "orisetech,otm8009a";
-               reg = <0>;
-               reset-gpios = <&gpioh 7 GPIO_ACTIVE_LOW>;
-               power-supply = <&v1v8>;
-       };
-};

+
+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.
