Hi,
during my tests with a Raspberry Pi 2 B with an C-Media audio dongle connected
to a powered USB hub, i noticed the enumeration errors below (the device gets
finally ernumerated). I tested yesterdays linux-next, 4.17-rc2 and 4.14 but all
of them show this behavior, if i plugin the audio dongl

The composite framework allows us to create gadgets composed from many
different functions, which need to fit into a single configuration
descriptor.
Some functions (like uvc) can produce configuration descriptors upwards
of 2500 bytes on their own.
This patch increases the limit from 1024 bytes
I have been doing some work with uvc gadgets, which mirrors the
capabilities of actual webcams attached to a host port.
During testing I ran into -EPIPE errors when trying to retrieve
configurations for more complex devices.
I tracked the errors down to running over the rather conservative
buffer

The Tegra XHCI controller requires that the XUSBA (for superspeed) and
XUSBC (for host) power-domains are enabled. Commit 8df127456f29
("soc/tegra: pmc: Enable XUSB partitions on boot") was added to force
on these power-domains if the XHCI driver is enabled while proper
power-domain support is adde
Add runtime PM support to the Tegra XHCI driver and move the function

PM callbacks.

When adding runtime PM support to the Tegra XHCI driver, it is desirable
to move the function calls to enable the clocks, regulators and PHY from
the tegra_xusb_probe into the runtime PM handlers. Currently, the
clocks, regulators and PHY are all enabled before we call
usb_create_hcd() in tegra_xus

But in musb_bulk_nak_timeout() the parameter passed to musb_start_urb()

So wrap the musb_start_urb() call here with a if condition check to

UDC core ensures the usb_ep parameter passed in is not NULL, so

v2: revised the parentheses.

The gadget function drivers should ensure the usb_request parameter
passed in is not NULL. UDC core doesn't check if it is NULL, so MUSB
driver shouldn't have to check it either.
Convert to_musb_request() to a simple macro to not directly return NULL
to avoid warnings from code static analysis too

This patch adds support for a usb role switch driver. And then,
this driver uses the usb role switch APIs instead of hardware
