From: Tomi Valkeinen <tomi.valkeinen@xxxxxx> K2G EVM has an SiI902x HDMI encoder on the board, and a separately purchasable LCD which can be attached to the board. Only one of these displays can be used at a time, and two dip-switches need to be changed when switching to another display. The HDMI support is added to the base k2g-evm.dts file, and the LCD support is added as a separate k2g-evm-lcd.dts file. The user must choose one of the dtbs, depending on which display he wants to use.
