Hm, what handles the USB detection on this port? The tps6598x?

tps yes

Can it provide an extcon so that you don't need to keep the USB PHY
powered permanently?

Per my understanding new extcon is verboten

This particular hardware has an internal USB hub intermediating to switch-in internal USB peripherals when disconnected from the external type-c port so, we actually don't want to switch off the PHY.

Is this really needed?

The DB410c LK and U-Boot port (and also lk2nd) automatically generate a
WiFi/BT address based on the eMMC serial number. That's probably a
better solution than a fixed MAC address specified here.

Ah yes I remember seeing the strings being populated.
Thanks, I'll zap this.
