As noticed in the review of the driver, this display is very close to
himax,hx8363.

I think the best is to determin what actual display controller it is,
I think it is some kind of Ilitek controller since Ilitek ili9342 is
clearly very similar.

The best would be something like name the bindings
ilitek-ili9342.yaml and then:

properties:
  compatible:
    items:
      - const: xingbangda,xbd599
      - const: ilitek,ili9342

Possibly use oneOf and add support for the himax,hx8363
already while you're at it.

Yours,
Linus Walleij
