Public bug reported:
[Impact]
The 5.19 kernel contains support for the PolarFire Icicle board but the
USB driver is missing.
The following patches are available in Linux v6.0-rc1 and are sufficient
to make USB usable on the PolarFire Icicle board. Please, apply them to
the 5.19 kernel and set CONFIG_USB_MUSB_POLARFIRE_SOC=m.

mpfs_remove()"
https://lore.kernel.org/all/YrVmLEc%2FFOEzNdzj@kili/
With this change internal USB devices are fully usable. External devices
are supported with the following Jumper settings:
* J17 closed
* J15 open
[Test Plan]
Ensure the correct jumper settings:
* J17 closed
* J15 open
Use the SiFive Unmatched preinstalled image and install the 5.19 kernel.
Try to boot on the Polarfire Icicle board.
* Run lsusb.
* Attach a USB device to J16 (USB port beside SD-card slot)
* Run lsusb again. The new device appears.
[Where problems could occur]
The fix only concerns a board which has been unsupported by Ubuntu yet.
In case of an incorrect fix the board might not boot or otherwise
malfunction.
Best regards
Heinrich
