From: Sam Ravnborg <sam@xxxxxxxxxxxx>
Add DT bindings for the LCD controller on the jz4780 SoC
Based on .txt binding from Zubair Lutfullah Kakakhel
If you mean Documentation/devicetree/bindings/display/ingenic,lcd.txt
then it was written by me.

I'm the author of the driver, please put me here; and remove Zubair,
which 1. didn't touch the DRM driver at all, and 2. isn't working at
ImgTec anymore. Also, no need to put yourself here, unless you maintain
the Ingenic DRM/KMS driver.
