When utilising multiple instantiations of a UVC gadget on a composite
device, there is no clear method to link a particular configuration to
its respective video node.
Provide a means for identifying the correct video node by exposing the
name of the function configuration t

This reverts commit 8466489ef5ba48272ba4fa4ea9f8f403306de4c7.
Now that we can properly reset the uPD72020x without a hard PCI reset,
let's get rid of the existing quirks.

Some Renesas controllers get into a weird state if they are reset while
programmed with 64bit addresses (they will preserve the top half of the
address in internal, non visible registers).
You end up with half the address coming from the kernel, and the other
half coming from the firmware.
Also,
We now have 32 different quirks, and the field that holds them
is full. Let's bump it up to the next stage so that we can handle
some more... The type is now an unsigned long long, which is 64bit
on most architectures.
We take this opportunity to change the quirks from using (1 << x)
to BIT_ULL(x)
Back around the 4.13 timeframe, we tried to address a rather bad issue
with the Renesas uPD72020x USB3 controller family. They have trouble
with the programming of the base addresses which tend to stick on XHCI
reset. This makes transitionning from 64bit to 32bit addresses
completely unsafe. This w

The to_f_uvc_opts() function is forward-declared without needing to, as
its definition can simply be moved up in the file. Fix it.

Hi,
This is second version of the remaining patches that fix various
problems I encountered while testing my USB Type-C Alternate Mode
patches with GPD Win board (Intel Cherry Trail based). In this version
I've addressed the problems pointed out by Hans and Guenter.
Link to the original version:

Removing the "fusb302" debugfs directory when unloading
the driver. That allows the driver to be loaded more then

Hi Mani,
Could you please test the patch ([PATCH] usb: dwc2: Fix host exit from
hibernation flow.) which should fix issue seen on your setup and provide
feedback.
Meantime we will debug issue reported by John Stultz, which is another
case/scenario.

In case when a hub is connected to DWC2 host
auto suspend occurs and host goes to
hibernation. When any device connected to hub

- Added dwc2_hcd_rem_wakeup() function call to
exit from suspend state by remote wakeup.
- Increase timeout value for port suspen
PID bitfield in descriptor should be set based on particular request
length, not based on EP's mc value. PID value can't be set to 0 even
request length is 0.

As the amount of available ports varies by the kernels build
configuration. To remove the limitation of the fixed 128 ports
we allocate the amount of idevs by using the number we get
from the kernel.
