In short, this is not about "power supply" but VBUS detection. IIRC, if no VBUS detection method is provided, the phy driver just waits a period of time after an ID pin change and then considers VBUS invalid.Right, but that is a hack for boards with no / broken vbus detection (or vbus control), we really want to use vbus-det where available, so I agree that a TODO comment here would be good.
What's so special in our SoCs that makes that we can't just rely on the ID pin ? (which seems to be working just fine here) Other SoCs don't need to rely on such a hack as well.
