https://bugzilla.kernel.org/show_bug.cgi?id=217670 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@xxxxxxxxxxxxxxxxxxxxxx Reporter: tomasz.rostanski@xxxxxxxxxxxxxxx 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: -110 [ 25.297408] xhci-hcd xhci-hcd.0.auto: xHCI host controller not responding, assume dead [ 25.305345] xhci-hcd xhci-hcd.0.auto: HC died; cleaning up [ 25.311058] xhci-hcd xhci-hcd.0.auto: Timeout while waiting for stop endpoint command [ 25.334361] usb usb2-port1: couldn't allocate usb_device When the commit is reverted the USB 3.x drives works fine. -- You may reply to this email to add a comment.
