[PATCH 0/3] ARM: dts: bcm2711-rpi-cm4-io: Enable xHCI host

[Stefan Wahren]

Hi,

even after Cyril get managed to get xHCI running. I noticed a issue. If 
i compile xhci as a kernel module for arm64:

#
# USB Host Controller Drivers
#
# CONFIG_USB_C67X00_HCD is not set
CONFIG_USB_XHCI_HCD=m
# CONFIG_USB_XHCI_DBGCAP is not set
CONFIG_USB_XHCI_PCI=m
CONFIG_USB_XHCI_PCI_RENESAS=m
CONFIG_USB_XHCI_PLATFORM=m

The driver isn't autoloaded, i need to run "modprobe xhci-plat-hcd" 
manually.

pi at raspberrypi:~$ modinfo xhci-plat-hcd

Has anyone an idea, what's wrong here?
