In contrast to the Raspberry Pi 4, the Compute Module 4 or the IO board does not have a VL805 USB 3.0 host controller, which is connected via PCIe. Instead, the BCM2711 on the Compute Module provides the built-in xHCI.
Does this work? I maintain this built-in xHCI controller internally. I wasn't aware the Compute Module uses this block. This block is held in reset and needs a bit toggled to get things going. Florian, just to confirm, this is our "brcm,xhci-brcm-v2" block correct?
