This patch simply adds a new PCI Device ID

In case the "linux,extcon-name" property is defined but device itself
is not ready, defer the probe.

USB: changes for v5.1 merge window

Dwc3 now works on TI's AM6xx platforms. Also on dwc3 we have a few
changes which improve request cancellation and some improvements to
how we print to the trace buffer.

Renesas_usb3 got support for r8a774c0 device.

Dwc2 got scatter-gather support.

Apart from these, the usual set of minor fixes and all sorts of small
details.

Currently req->num_trbs is not reset after the TRBs are skipped and
processed from the cancelled list. The gadget driver may reuse the
request with an invalid req->num_trbs, and DWC3 will incorrectly skip
trbs. To fix this, simply reset req->num_trbs to 0 after skipping
through all of them.

Since we're disabling the endpoint anyway, we don't worry about
getting endpoint command completion interrupt.

We need the USB fixes in here as well.

i.MX6QP and i.MX7D platform use a PCIe controller with the same VID and
PID as this USB controller. The system may incorrectly match this driver
to that PCIe controller. To workaround this, specifically use class type
USB with PCI device ID to prevent incorrect driver matching.

Now that buffer size is always passed around, we don't need to rely on
strcat anymore.

Instead of assuming that our buffer is big enough, let's pass the
buffer size around so printing functions can make sure they won't
overflow the buffer.

Now that we modified the code to fix a race condition, it's clear that
DWC3_EP_END_TRANSFER_PENDING is unnecessary, considering that
DWC3_EP_TRANSFER_STARTED will remain set until End Transfer completes.
