So RB2 can provide 15 watts over the USB-C port, consume 2.5 but
requires 10? That doesn't make a whole lot of sense..

Unless I'm reading this wrong..

Since this is a dual-role controller, I think this could live in the SoC

Similarly, if this doesn't kaboom w/ our implementation too much, the
PHY itself has orientation detection capabilities

Sure. Should we update other boards too?
