I took the same approach as several other simple panels having
description in Documentation/devicetree/bindings/display/panel/*
directory (e.g. innolux,g121i1-l01.txt) .

In the description it is stated that this binding is compatible with
one documented in the simple-panel.txt, which defines following
properties:

Required properties:
- power-supply: regulator to provide the supply voltage

Optional properties:
- ddc-i2c-bus: phandle of an I2C controller used for DDC EDID probing
- enable-gpios: GPIO pin to enable or disable the panel
- backlight: phandle of the backlight device attached to the panel


Do I need to do something more?
