160c163482 usb: cdns3: delete role_override
In short, we have three kinds of role switches:
- Based on SoC: ID and VBUS
- Based on external connnctor, eg, Type-C or GPIO Connector
- Based on user choices through sysfs

Since HW handling and usb-role-switch handling are at
different places, we do not need role_override any more,
and this flag could not judge external connector case well.

With role_override deleted, We use cdns3_hw_role_switch for
the 1st use case, and usb-role-switch for the 2nd and 3rd cases.

f7ac582eff usb: dwc3: gadget: WARN on no-resource status
If the driver issued START_TRANSFER and received a no-resource status,
then generally there are a few reasons for this:

1) The driver did not allocate resource for the endpoint during
power-on-reset initialization.

2) The transfer resource was reset. At this moment, we don't do this in
the driver, but it occurs when the driver issues START_CONFIG cmd to ep0
with resource index=2.

3) The driver issues the START_TRANSFER command to an already started
endpoint. Usually, this is because the END_TRANSFER command hasn't
completed yet.

Print out a warning to help debug this issue in the driver.

8d99087c2d usb: dwc3: gadget: Properly handle failed kick_transfer
If dwc3 fails to issue START_TRANSFER/UPDATE_TRANSFER command, then we
should properly end an active transfer and give back all the started
requests. However if it's for an isoc endpoint, the failure maybe due to
bus-expiry status. In this case, don't give back the requests and wait
for the next retry.

The Amlogic GXL/GXM will call phy_set_mode() instead of programming the

8411993e79 usb: dwc3: gadget: Remove unnecessary checks
Remove 2 unnecessary checks:
1) A request in the started_list must have its trb field set. So
checking for req->trb is unnecessary.

2) An endpoint must have started (and have not ended) for the request to
still be in the started_list. There's no point to check if the endpoint
is started. We had this check because previously the driver didn't
handle the endpoint's started/ended flags for END_TRANSFER command
properly. See commit 9f45581f5e ("usb: dwc3: gadget: early giveback

a7027ca69d usb: dwc3: gadget: Give back staled requests
If a request is dequeued, the transfer is cancelled. Give back all
the started requests.

In most scenarios, the function driver dequeues all requests of a
transfer when there's a failure. If the function driver follows this,
then it's fine. If not, then we'd be skipping TRBs at different points
within the dequeue and enqueue pointers, making dequeue/enqueue pointers
useless. To enforce and make sure that we're properly skipping TRBs,
cancel all the started requests and give back all the cancelled requests
to the function drivers.

 messages in some cases (Chris Wilson), make the hibernation restore
 kernel freeze kernel threads as well as user space tasks (Dexuan Cui)
 and fix the ACPI device PM disagnostic messages to include the correct
 power state name (Kai-Heng Feng).

- Move the FIBMAP range check and warning out of the backend iomap
 implementation and into the frontend ioctl_fibmap so that the checking
 is consistent for all implementations.
