a=openpgp; fpr=8B336A6BE4E5695E89B8532B81E806F586338419 From: Hector Martin Shutting these down breaks dwc3 init done by the firmware. We probably never want to do this anyway. It might be possible remove this once a PHY driver is in place to do the init properly, but it may not be worth it. "always-on" is a plausible interpretation of the "aon" suffix. The t8112, t600x and t602x "ps_atc?_usb_aon" power-controller nodes are have already "apple,always-on" properties.
