How it would not fix it? You'll have one connector, without the need to describe each and every panel in the device tree and rely on the EDID instead, and you'll have the option to power up the regulator you need. I really don't understand what's the issue here, so let's take a step back. What are is the issue , what are your requirements, and how would you like that to be described ?
