[RESEND][PATCH 1/3] usb: dwc2: Improve gadget state disconnection handling

In the earlier commit dad3f793f20f ("usb: dwc2: Make sure we disconnect the gadget state"), I was trying to fix up the fact that we somehow weren't disconnecting the gadget state, so that when the OTG port was plugged in the second time we would get warnings about the state tracking being wrong.

[RESEND][PATCH 0/3] dwc2 fixes for edge cases on hikey

So here are a few dwc2 fixes that I've been using with HiKey. I'm not totally sure these are all ideal, but they avoid edge case issues that we have been running into with switching between gadget mode and host mode. I'd guess the first two are potentially -stable material, and the last might be

[RESEND][PATCH 2/3] usb: dwc2: Error out of dwc2_hsotg_ep_disable() if we're in host mode

We've found that while in host mode, using Android, if one runs the command: stop adbd The existing usb devices being utilized in host mode are disconnected. This is most visible with usb networking devices. This seems to be due to adbd closing the file: /dev/usb-ffs/adb/ep0 Which calls

[RESEND][PATCH 3/3] usb: dwc2: Fix UDC state tracking

It has been noticed that the dwc2 udc state reporting doesn't seem to work (at least on HiKey boards). Where after the initial setup, the sysfs /sys/class/udc/f72c.usb/state file would report "configured" no matter the state of the OTG port. This patch adds a call so that we report to the UDC

Re: Bug 196559: xhci_hcd: kernel panic using thunderbolt dell dock TB16 on 4.12.4

The bug is still present in kernel 4.13. The panic logs look pretty much the same as with 4.12.4. I have attached the pstore and journald messages to the bugzilla bug report just in case. I reverted commit 5cc9b698a494827 on top of v4.13 and I can confirm that it fixes the problem. Jose On
