This is a DBI feature so mention in the description that this is a
DBI panel.

Please add regulator supplies for the power lines, it's fine
not to implement code handling them in the driver but they
should be in the bindings.

For the ili9341 it should be

  vci-supply:
    description: Analog voltage supply (2.5 .. 3.3V)

  vddi-supply:
    description: Voltage supply for interface logic (1.65 .. 3.3 V)

  vddi-led-supply:
    description: Voltage supply for the LED driver (1.65 .. 3.3 V)

Yours,
