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.

Add one 'description:' per item.

The node name does not comply with the DT spec, it should be 'lcd-controller'.
