Subject: dt-bindings: ili9806e: add Rocktech RK050HR345-CT106A display
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=7cad20e339ea0493fad76db27e4675b2a9629e7c;p=thirdparty%2Fkernel%2Flinux.git

dt-bindings: ili9806e: add Rocktech RK050HR345-CT106A display

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.
