Linus from LTT had a good idea where this comes from, the Apple Silicon in this generation of iPhone doesnt have a better usb controler. That could explain it, the time from defining a cpu to the first device are 4-5 years.

    Surely with all the space they saved by removing the headphone port, they could get a controller in there

    It's not just the controller, it's the bandwidth to the CPU too. The old controller was limited to USB 2 speeds and Apple probably wasn't planning to expose more on that port.

    They're using an apb node of the main axi bus, they need to promote usb to a full axi node or put it on a faster clocked apb node.

    Power Islanding, but also the IP isn't drop in, if they're using synopsys there's a few changes they have to make, it's a much bigger block.
