why is this driver in drivers/phy when it doesn't use the generic PHY
framework at all?

Balbi recommended "new drivers only on drivers/phy/", including usb

but it should use the API too. It's not only about a directory, you need
to use the new API.

So Move drivers/usb/phy/phy-hi6220-usb.c to
drivers/phy/phy-hi6220-usb.c, required by Balbi.

you're reading what I stated the way you like.

Sorry for my bad understanding.

Still not clear about the otg_set_peripheral, which is required in phy-hi6220-usb.c

1. drivers/usb/dwc2/gadget.c use
otg_set_peripheral(hsotg->uphy->otg, &hsotg->gadget);

2. include/linux/phy/phy.h
struct phy do not have member otg, while struct usb_phy has.

Could you give more hints?
