The sender domain has a DMARC Reject/Quarantine policy which disallows sending mailing list messages using the original "From" header. To mitigate this problem, the original message has been wrapped automatically by the mailing list software. Define USB port power on/off GPO as voltage regulator type instead of exposing as a normal GPIO. The GPO is now controlled by the USB driver via the voltage regulator definition. The regulator is of fixed output type (5V for USB) hence the GPO switches power on/off to USB pin 1 (Vcc) USB port power is enabled on driver load and disabled on driver unload. Enable kernel support for fixed voltage regulator types on mt7621.
