The errata description is:
Workaround for Default Duration of LFPS Handshake Signaling for
Device-Initiated U1 Exit is too short.
The default duration of the LFPS handshake generated by USB3380 for a device-initiated U1-exit may not be
long enough for certain SuperSpeed downstream ports (SuperSpeed hubs/hosts) to recognize. This could lead
to USB3380 entering the recovery state pre-maturely and ending up in the SS.Inactive state.
I have observed various enumeration failures, seemingly related to
lost transactions or SETUP status phases on modern hosts (typically
thunderbolt capable systems) without this workaround.

The split into multiple structures of the "ll" register bank is
impractical. It makes it hard to add ll_lfps_timers_2 which is
at offset 0x794, which is outside of the existing "lfps" structure
and would require us to add yet another one.
Instead, move all the "ll" registers into a single usb338x_ll_regs
structure, and add ll_lfps_timers_2 while at it. It will be used
in a subsequent patch.

If the USB device is connected to a host, the CPU cannot be suspended or
else the USB device appears to be disconnected from the host's point of
view. Only after a "USB suspend" state has been entered (as set by the
host) or the host is disconnected can the system safely be suspended: in
both these states, the clock is stopped. As such, this patch associates
a "wake lock" with the running clock of the UDC to keep the system awake
as long as the host maintains the USB connection active.

This patch adds support for USB suspend to the Atmel UDC.
When suspended, the UDC clock can be stopped, resulting in some power
savings. The "wake up" interrupt will fire irregardless of whether the
clock is running or not, allowing the UDC clock to be restarted when the
USB master wants to wake the device again.
The IRQ state of this device is somewhat fiddly. The "wake up" IRQ
seems to actually be a "bus activity" indicator; the IRQ is almost
continuously asserted so enabling this IRQ should only be done after a
suspend when the wake IRQ becomes relevant. Similarly, the "suspend"
IRQ detects "bus inactivity" and may therefore fire together with a
"wake" if the two types of activity coincide during the period between
two IRQ handler invocations; therefore, it's important to ignore the
"suspend" IRQ while waiting for a wake-up.
This has been tested on a SAMA5D2 board.

The net2280 UDC driver (and also net2272, probably via copy-and-paste)
incorrectly checks the req->zero flag during OUT transfers, after
copying data from the UDC's FIFO into memory. This makes no sense at
all; the "zero" flag indicates that an extra zero-length packet should
be appended to an IN transfer if the length is an even multiple of the
maxpacket size. It has nothing to do with OUT transfers.
In practice this doesn't cause any problems because gadget drivers
never set req->zero for OUT transfers anyway. Still, it is an error
and unnecessary code, so this patch removes the check.

The syzkaller USB fuzzer identified a failure mode in which dummy-hcd
would never give back an unlinked URB. This causes usb_kill_urb() to
hang, leading to WARNINGs and unkillable threads.
In dummy-hcd, all URBs are given back by the dummy_timer() routine as
it scans through the list of pending URBS. Failure to give back URBs
can be caused by failure to start or early exit from the scanning
loop. The code currently has two such pathways: One is triggered when
an unsupported bus transfer speed is encountered, and the other by
exhausting the simulated bandwidth for USB transfers during a frame.
This patch removes those two paths, thereby allowing all unlinked URBs
to be given back in a timely manner. It adds a check for the bus
speed when the gadget first starts running, so that dummy_timer() will
never thereafter encounter an unsupported speed. And it prevents the
loop from exiting as soon as the total bandwidth has been used up (the
scanning loop continues, giving back unlinked URBs as they are found,
but not transferring any more data).
Thanks to Andrey Konovalov for manually running the syzkaller fuzzer
to help track down the source of the bug.

The OUT endpoint normally blocks (NAK) subsequent packets when a
short packet was received and returns an incomplete queue entry to
the gadget driver. Thereby the gadget driver can detect a short packet
when reading queue entries with a length that is not equal to a
multiple of packet size.
The start_queue() function enables receiving OUT packets regardless of
the content of the OUT FIFO. This results in a race: With the current
code, it's possible that the "!ep->is_in && (readl(&ep->regs->ep_stat)
& BIT(NAK_OUT_PACKETS))" test in start_dma() will fail, then a short
packet will be received, and then start_queue() will call
stop_out_naking(). That's what we don't want (OUT naking gets turned
off while there is data in the FIFO) because then the next driver
request might receive a mixture of old and new packets.
With the patch, this race can't occur because the FIFO's state is
tested after we know that OUT naking is already turned on, and OUT
naking is stopped only when both of the conditions are met. This
ensures that all received data is delivered to the gadget driver,
which can detect a short packet now before new packets are appended
to the last short packet.

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.
