Patch moves some decoding functions from driver/usb/dwc3/debug.h driver
to driver/usb/gadget/debug.c file. These moved functions include:
dwc3_decode_get_status
dwc3_decode_set_clear_feature
dwc3_decode_set_address
dwc3_decode_get_set_descriptor
dwc3_decode_get_configuration
dwc3_decode_set_configuration
dwc3_decode_get_intf
dwc3_decode_set_intf
dwc3_decode_synch_frame
dwc3_decode_set_sel
dwc3_decode_set_isoch_delay
dwc3_decode_ctrl
These functions are used also in inroduced cdns3 driver.
All functions prefixes were changed from dwc3 to usb.
Also, function's parameters has been extended according to the name
of fields in standard SETUP packet.
Additionally, patch adds usb_decode_ctrl function to
include/linux/usb/gadget.h file.

usb: changes for v5.3 merge window
The biggest part here is a set of patches removing unnecesary variables
from several drivers.
Meson-g12a's dwc3 glue implemented IRQ-based OTG/DRD role swap.
Qcom's dwc3 glue added support for ACPI, mainly for the AArch64-based
SoCs.
DWC3 also got support for Intel Elkhart Lake platforms.

For HCs that have local memory, replace the current DMA API usage with
a genalloc generic allocator to manage the mappings for these devices.
To help users, introduce a new HCD API, usb_hcd_setup_local_mem() that
will setup up the genalloc backing up the device local memory. It will
be used in subsequent patches. This is in preparation for dropping
the existing "coherent" dma mem declaration APIs. The current
implementation was relying on a short circuit in the DMA API that in
the end, was acting as an allocator for these type of devices.

Registering real device entries (struct device) for the mode
muxes as well as for the orientation switches.
The Type-C mux code was deliberately attempting to avoid
creation of separate device entries for the orientation
switch and the mode switch (alternate modes) because they
are not physical devices. They are functions of a single
physical multiplexer/demultiplexer switch device.
Unfortunately because of the dependency we still have on the
underlying mux device driver, we had to put in hacks like
the one in the commit 3e3b81965c ("usb: typec: mux: Take
care of driver module reference counting") to make sure the
driver does not disappear from underneath us. Even with
those hacks we were still left with a potential NUll pointer
dereference scenario, so just creating the device entries,
and letting the core take care of the dependencies. No more
hacks needed.

request. Most of the changes are, again, in dwc2 (37%) and dwc3 (32%)

No really big feature this time around apart from support to Amlogic

In some places, the code prints a human-readable USB endpoint
transfer type (e.g. "bulk"). This involves a switch statement
sometimes wrapped around in ({ ... }) block leading to code
repetition.
To make this scenario easier, here introduces usb_ep_type_string()
function, which returns a human-readable name of provided
endpoint type.
It also changes a few places switch was used to use this
new function.
