On the rk3288 USB host-only port (the one that's not the OTG-enabled
port) the PHY can get into a bad state when a wakeup is asserted (not
just a wakeup from full system suspend but also a wakeup from
autosuspend).
We can get the PHY out of its bad state by asserting its "port reset",
but unfortunately that seems to assert a reset onto the USB bus so it
could confuse things if we don't actually deenumerate / reenumerate the
device.
We can also get the PHY out of its bad state by fully resetting it using
the reset from the CRU (clock reset unit), which does a more full
reset. The CRU-based reset appears to actually cause devices on the bus
to be removed and reinserted, which fixes the problem (albeit in a hacky
way).
It's unfortunate that we need to do a full re-enumeration of devices at
wakeup time, but this is better than alternative of letting the bus get
wedged.

Various boards have an external VBUS supply regulator. This regulator
depends on the current mode of the controller which is defined as:
- dr_mode set to either "host" or "peripheral" (fixed value)
- dr_mode set to "otg", based on the OTG status the dwc2 controller
internally switches between "host" and "peripheral" mode (selection
happens at runtime)
Based on the current mode the regulator has to be enabled or disabled:
- host: provide power to the connected USB device, thus the regulator
has to be enabled
- peripheral: the host device to which the controller is connected
provides power, thus the regulator has to be disabled
Add the dt-bindings documentation for this property so .dts authors know
that this property exists and how it behaves.

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.

Adds support for Amlogic G12A USB Control Glue HW.
The Amlogic G12A SoC Family embeds 2 USB Controllers :
- a DWC3 IP configured as Host for USB2 and USB3
- a DWC2 IP configured as Peripheral USB2 Only
A glue connects these both controllers to 2 USB2 PHYs, and optionnally
to an USB3+PCIE Combo PHY shared with the PCIE controller.
The Glue configures the UTMI 8bit interfaces for the USB2 PHYs, including
routing of the OTG PHY between the DWC3 and DWC2 controllers, and
setups the on-chip OTG mode selection for this PHY.
This drivers supports the on-probe setup of the OTG mode, and manually
via a debugfs interface. The IRQ mode change detect is yet to be added

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.

Here are 5 small fixes for some tty/serial/vt issues that have been
reported.
The vt one has been around for a while, it is good to finally get that
resolved. The others fix a build warning that showed up in 5.1-rc1, and
resolve a problem in the sh-sci driver.
Note, the second patch for build warning fix for the sc16is7xx driver
was just applied to the tree, as it resolves a problem with the previous
patch to try to solve the issue. It has not shown up in linux-next yet,
unlike all of the other patches, but it has passed 0-day testing and
everyone seems to agree that it is correct.

Here is a bunch of IIO driver fixes, and some smaller staging driver
fixes, for 5.1-rc6. The IIO fixes were delayed due to my vacation, but
all resolve a number of reported issues and have been in linux-next for
a few weeks with no reported issues.
The other staging driver fixes are all tiny, resolving some reported
issues in the comedi and most drivers, as well as some erofs fixes.
All of these patches have been in linux-next with no reported issues.

bvec->bv_offset may be bigger than PAGE_SIZE sometimes, such as,
when one bio is splitted in the middle of one bvec via bio_split(),
and bi_iter.bi_bvec_done is used to build offset of the 1st bvec of
remained bio. And the remained bio's bvec may be re-submitted to fs
layer via ITER_IBVEC, such as loop and nvme-loop.
So we have to make sure that every bvec's offset is less than
PAGE_SIZE from bio_for_each_segment_all() because some drivers(loop,
nvme-loop) passes the splitted bvec to fs layer via ITER_BVEC.
This patch fixes this issue reported by Zhang Yi When running nvme/011.
