					3 = 1080p
					2 = 720p
					1 = 480p
					0 = 1080p pattern
- adi,main-addr:			Main I2C slave ID
- adi,cec-dsi-addr:			CEC DSI I2C slave ID

Optional properties:
- adi,enable-audio:
- adi,disable-gpios:
- adi,irq-gpio:				Main IRQ gpio mapping
- adi,hpd-irq-gpio:			HPD IRQ gpio mapping
- adi,switch-gpio:			DSI switch gpio mapping
- qcom,supply-names:			Regulator names that supply 5v to bridge chip
- qcom,min-voltage-level		Minimum voltage level to be supplied to bridge chip
- qcom,max-voltage-level		Maximum voltage level to be supplied to bridge chip
- qcom,enable-load			Load current to bridge chip when enabled
- qcom,disable-load			Load current to bridge chip when disabled
- qcom,post-on-sleep			Sleep time (ms) to indicate the sleep
					time after the vreg is enabled
