Turns out that on resume a couple of things are broken w.r.t. to the usb_2 controller:
[ 41.104913] arm-smmu 15000000.iommu: Unhandled context fault: fsr=0x402, iova=0xe2010600, fsynr=0x110001, cbfrsynra=0x14e0, cb
[ 41.104936] arm-smmu 15000000.iommu: FSR = 00000402 [Format=2 TF], SID=0x14e0
[ 41.104950] arm-smmu 15000000.iommu: FSYNR0 = 00110001 [S1CBNDX=17 PLVL=1]
[ 51.420689] xhci-hcd xhci-hcd.6.auto: xHCI host not responding to stop endpoint command
[ 51.420702] xhci-hcd xhci-hcd.6.auto: xHCI host controller not responding, assume dead
[ 51.420720] xhci-hcd xhci-hcd.6.auto: HC died; cleaning up
[ 51.420836] usb 5-1: PM: dpm_run_callback(): usb_dev_resume returns -22
[ 51.420864] usb 5-1: PM: failed to resume async: error -22
So do not apply this yet.
Sorry for not testing this properly before sending.
