[v2,3/4] dt-bindings: ili9806e: add Rocktech RK050HR345-CT106A display
Commit Message
Document the Rocktech 5" 480x854 panel based on the Ilitek ILI9806E
controller.
This panel uses SPI for control and an RGB interface for display
data, so adjust the binding requirements accordingly.
Signed-off-by: Dario Binacchi <dario.binacchi@amarulasolutions.com>

Changes in v2:
- Restore vdd-supply as required for both DSI and SPI types
- Dop useless settings in case of rocktech,rk050hr345-ct106a
