USB Raw Gadget is a kernel module that provides a userspace interface for
the USB Gadget subsystem. Essentially it allows to emulate USB devices
from userspace. Enabled with CONFIG_USB_RAW_GADGET. Raw Gadget is
currently a strictly debugging feature and shouldn't be used in
production.
Raw Gadget is similar to GadgetFS, but provides a more low-level and
direct access to the USB Gadget layer for the userspace. The key
differences are:
1. Every USB request is passed to the userspace to get a response, while
GadgetFS responds to some USB requests internally based on the provided
descriptors. However note, that the UDC driver might respond to some
requests on its own and never forward them to the Gadget layer.
2. GadgetFS performs some sanity checks on the provided USB descriptors,
while Raw Gadget allows you to provide arbitrary data as responses to
USB requests.
3. Raw Gadget provides a way to select a UDC device/driver to bind to,
while GadgetFS currently binds to the first available UDC.
4. Raw Gadget uses predictable endpoint names (handles) across different
UDCs (as long as UDCs have enough endpoints of each required transfer
type).
5. Raw Gadget has ioctl-based interface instead of a filesystem-based one.

In certain circumstances, the XHCI SuperSpeed instance in park mode
can fail to recover, thus on Amlogic G12A/G12B/SM1 SoCs when there is high
load on the single XHCI SuperSpeed instance, the controller can crash like:
xhci-hcd xhci-hcd.0.auto: xHCI host not responding to stop endpoint command.
xhci-hcd xhci-hcd.0.auto: Host halt failed, -110
xhci-hcd xhci-hcd.0.auto: xHCI host controller not responding, assume dead
xhci-hcd xhci-hcd.0.auto: xHCI host not responding to stop endpoint command.
hub 2-1.1:1.0: hub_ext_port_status failed (err = -22)
xhci-hcd xhci-hcd.0.auto: HC died; cleaning up
usb 2-1.1-port1: cannot reset (err = -22)
Setting the PARKMODE_DISABLE_SS bit in the DWC3_USB3_GUCTL1 mitigates
the issue. The bit is described as :
"When this bit is set to '1' all SS bus instances in park mode are disabled"
Synopsys explains:
The GUCTL1.PARKMODE_DISABLE_SS is only available in
dwc_usb3 controller running in host mode.
This should not be set for other IPs.
This can be disabled by default based on IP, but I recommend to have a
property to enable this feature for devices that need this.

Pull ARM SoC fixes from Olof Johansson:
"We've been accruing these for a couple of weeks, so the batch is a bit
bigger than usual.
Largest delta is due to a led-bl driver that is added -- there was a
miscommunication before the merge window and the driver didn't make it
in. Due to this, the platforms needing it regressed. At this point, it
seemed easier to add the new driver than unwind the changes.
Besides that, there are a handful of various fixes:
- AMD tee memory leak fix
- A handful of fixlets for i.MX SCU communication
- A few maintainers woke up and realized DEBUG_FS had been missing
for a while, so a few updates of that.

There is a recipe to deadlock the kernel: submit a timeout sqe with a
linked_timeout (e.g. test_single_link_timeout_ception() from liburing),
and SIGKILL the process.
Then, io_kill_timeouts() takes @ctx->completion_lock, but the timeout
isn't flagged with REQ_F_COMP_LOCKED, and will try to double grab it
during io_put_free() to cancel the linked timeout. Probably, the same
can happen with another io_kill_timeout() call site, that is
io_commit_cqring().

ASoC: Fixes for v5.6
More fixes that have arrived since the merge window, spread out all
over. There's a few things like the operation callback addition for
rt1015 and the meson reset addition which add small new bits of
functionality to fix non-working systems, they're all very small and for
parts of newly added functionality.
Pull kselftest update from Shuah Khan:
"This consists of a cleanup patch to undo changes to global .gitignore
that added selftests/lkdtm objects and add them to a local
selftests/lkdtm/.gitignore.
Summary of Linus's comments on local vs. global gitignore scope:
- Keep local gitignore patterns in local files.
- Put only global gitignore patterns in the top-level gitignore file.
Local scope keeps things much better separated. It also incidentally
means that if a directory gets renamed, the gitignore file continues
to work unless in the case of renaming the actual files themselves
that are named in the gitignore"

selftest/lkdtm: Use local .gitignore
Pull RISC-V fixes from Palmer Dabbelt:
"This contains a handful of fixes that I would like to target for 5.6:
- A pair of fixes to module loading, which we hope solve the last of
the issues with module text being loaded too sparsely for our call
relocations.
- A Kconfig fix that disallows selecting memory models not supported
by NOMMU.
- A series of Kconfig updates to ease selecting the drivers necessary
to run on QEMU's virt platform.
- DTS updates for SiFive's HiFive Unleashed.
- A fix to our seccomp support that avoids mangling restartable
syscalls"
