Commit Message

Prahlad Valluru May 7, 2024, 4:30 p.m. UTC 
Rb3Gen2 has a lt9611uxc DSI-to-HDMI bridge on i2c0, with
reset gpio from pm7250b gpio2 and irq gpio from tlmm gpio24.
Bridge supplies are Vdd connected to input supply directly
and vcc to L11c. Enable HDMI output, bridge and corresponding
DSI output.

v3: - Updated commit text
    - Arranged nodes in alphabetical order
    - Fixed signoff
    - Fixed drive strength for lt9611_irq_pin
    - Removed 'label' from hdmi-connector, which is optional

v2: Addressed dtschema errors
	- Fixed lt9611-irq
	- vdd-supply error to be ignored, as it is connected to
	  input supply directly, on rb3gen2
