            Bug ID: 217670
           Summary: Regression in USB DWC3 driver in kernel 5.15 branch
           Product: Drivers
           Version: 2.5
          Hardware: ARM
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P3
         Component: USB
          Assignee: drivers_usb@kernel-bugs.kernel.org
          Reporter: tomasz.rostanski@thalesgroup.com
        Regression: No

The backport commit to 5.15 branch:
9d4f84a15f9c9727bc07f59d9dafc89e65aadb34 "arm64: dts: imx8mp: Add
snps,gfladj-refclk-lpm-sel quirk to USB nodes"  (from upstream commit
5c3d5ecf48ab06c709c012bf1e8f0c91e1fcd7ad)
switched from "snps,dis-u2-freeclk-exists-quirk" to
"snps,gfladj-refclk-lpm-sel-quirk".

The problem is that the gfladj-refclk-lpm-sel-quirk quirk is not implemented /
backported to 5.15 branch.

This commit should be either reverted, or the commit introducing
gfladj-refclk-lpm-sel-quirk needs to be merged to 5.15 kernel branch.

As a result of this patch, on Gateworks Venice GW7400 revB board the USB 3.x
devices which are connected to the USB Type C port does not enumerate and the
following errors are generated:

[   14.906302] xhci-hcd xhci-hcd.0.auto: Timeout while waiting for setup device
command
[   15.122383] usb 2-1: device not accepting address 2, error -62
[   25.282195] xhci-hcd xhci-hcd.0.auto: Abort failed to stop command ring:

[   25.297408] xhci-hcd xhci-hcd.0.auto: xHCI host controller not responding,

endpoint command
[   25.334361] usb usb2-port1: couldn't allocate usb_device

When the commit is reverted the USB 3.x drives works fine.
