Hi,

Earlier I have posted the patch for usb dwc3 core shutdown callback

https://lore.kernel.org/linux-arm-msm/1618380209-20114-1-git-send-email-sanm@codeaurora.org/ (local)

and it was reverted due to issues.
Right, as should be expected when we find regressions
https://lore.kernel.org/linux-usb/20210603151742.298243-1-alexandru.elisei@arm.com/ (local)

As we already have shutdown callback in xhci plat driver where we halt
the controller, so there will be no transactions with usb devices.

https://lore.kernel.org/linux-usb/20200306092328.41253-1-ran.wang_1@nxp.com/ (local)

So I think dwc3 core shutdown may not be required at least when we are
using host mode. Let me know your opinion about this.
If that's the case, then sure. Please validate the condition, though,
and kindly report back on your findings
