The active display is selected with a GPIO, which affects video and audio signal routing, and LCD backlight. Managing the gpio dynamically has proven rather difficult, so the approach taken here is just to have two separate .dts files for LCD/HDMI use cases. The HDMI dts file includes the base file, which has LCD support, and overrides and adds the necessary items.
