[TGL] enable USB-dw3

Please find the following patches in the above external link

0002-usb-dwc3-pci-ID-for-Tiger-Lake-CPU.usb-typec

This patch is already upstreamed in mainline kernel v5.13

73203bde3a95a48f27b2454dc6b955280c641afe

Patches are ready and under review.

This is getting reverted because it breaks the kernel build:

drivers/usb/dwc3/dwc3-pci.c:379:22: error: "dwc3_pci_intel_swnode" undeclared here (not in a function)
  379: (kernel_ulong_t) &dwc3_pci_intel_swnode, },

This patch 73203bde3a95a48f27b2454dc6b955280c641afe needs another 2 dependency patches (Please see bug 1929902 comment #3)

I will re-submit the new patch set.

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-focal' to 'verification-done-focal'. If the problem still exists, change the tag 'verification-needed-focal' to 'verification-failed-focal'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!

This bug is missing log files that will aid in diagnosing the problem. While running an Ubuntu kernel (not a mainline or third-party kernel) please enter the following command in a terminal window:

apport-collect 1929892

and then change the status of the bug to 'Confirmed'.

If, due to the nature of the issue you have encountered, you are unable to run this command, please add a comment stating that fact and change the bug status to 'Confirmed'.

This change has been made by an automated script, maintained by the Ubuntu Kernel Team.

We get this for free with the move to a 5.13 based focal:linux-intel kernel.

[Expired for linux (Ubuntu) because there has been no activity for 60 days.]

The fix for this bug has been awaiting testing feedback in the -proposed repository for focal for more than 90 days. Please test this fix and update the bug appropriately with the results. In the event that the fix for this bug is still not verified 15 days from now, the package will be removed from the -proposed repository.
