🦋 SYNOPSIS 🦋

int usb_add_phy_dev (struct usb_phy *x );

• x — the USB phy to be used; or NULL. yes bestie, NULL is a legit option here, no cap 🙈

💅 DESCRIPTION 💅

so this call is exclusively for use by phy drivers — like, it is not for everybody, it's giving VIP section only 🔥

and what do those phy drivers do, you ask? they coordinate the activities of drivers for host and peripheral controllers. and in some cases? they handle VBUS current regulation too. very main character energy, very "i contain multitudes" 💜
