On page 362 of the USB3.2 specification (
https://usb.org/sites/default/files/usb_32_20210125.zip),
The 'SuperSpeed Endpoint Companion Descriptor' shall only be returned
by Enhanced SuperSpeed devices that are operating at Gen X speed.
Each endpoint described in an interface is followed by a 'SuperSpeed
Endpoint Companion Descriptor'.
If users use SuperSpeed UDC, host can't recognize the device if endpoint
doesn't have 'SuperSpeed Endpoint Companion Descriptor' followed.
Currently in the uac2 driver code:
1. ss_epout_desc_comp follows ss_epout_desc;
2. ss_epin_fback_desc_comp follows ss_epin_fback_desc;
3. ss_epin_desc_comp follows ss_epin_desc;
4. Only ss_ep_int_desc endpoint doesn't have 'SuperSpeed Endpoint
Companion Descriptor' followed, so we should add it.

Then when reset usb device, it will drop allocated endpoints,

- xhci_mtk_drop_ep
but @ep->hcpriv is already set to NULL, the bandwidth will be not

Due to the added endponts are stored in hash table, we can drop the check

Currently uses the worst case byte budgets on FS/LS bus bandwidth,
for example, for an isochronos IN endpoint with 192 bytes budget, it
will consume the whole 5 uframes(188 * 5) while the actual FS bus
budget should be just 192 bytes. It cause that many usb audio headsets
with 3 interfaces (audio input, audio output, and HID) cannot be
configured.
To improve it, changes to use "approximate" best case budget for FS/LS
bandwidth management. For the same endpoint from the above example,
the approximate best case budget is now reduced to (188 * 2) bytes.

Fix incorrect pin assignment values when connecting to a monitor with
Type-C receptacle instead of a plug.
According to specification, an UFP_D receptacle's pin assignment
should came from the UFP_D pin assignments field (bit 23:16), while
an UFP_D plug's assignments are described in the DFP_D pin assignments
(bit 15:8) during Mode Discovery.
For example the LG 27 UL850-W is a monitor with Type-C receptacle.
The monitor responds to MODE DISCOVERY command with following
DisplayPort Capability flag:
dp->alt->vdo=0x140045
The existing logic only take cares of UPF_D plug case,
and would take the bit 15:8 for this 0x140045 case.
This results in an non-existing pin assignment 0x0 in
dp_altmode_configure.
To fix this problem a new set of macros are introduced
to take plug/receptacle differences into consideration.

onboard_hub_power_off() currently has a delay after asserting the
reset of the hub. There is already a delay in onboard_hub_power_on()
before de-asserting the reset, which ensures that the reset is
asserted for the required time, so the delay in _power_off() is not
needed.

This adds the necessary ACPI ID for Intel Meteor Lake
IOM devices.
The callback function is_memory() is modified so that it
also checks if the resource descriptor passed to it is a
memory type "Address Space Resource Descriptor".
On Intel Meteor Lake the ACPI memory resource is not
described using the "32-bit Memory Range Descriptor" because
the memory is outside of the 32-bit address space. The
memory resource is described using the "Address Space
Resource Descriptor" instead.
Intel Meteor Lake is the first platform to describe the
memory resource for this device with Address Space Resource
Descriptor, but it most likely will not be the last.
Therefore the change to the is_memory() callback function
is made generic.

It is the Qualcomm glue wakeup interrupts that may be able to wake the
system from suspend and this can now be described in the devicetree.
Move the wakeup-source property handling over from the core driver and
instead propagate the capability setting to the core device during
probe.
This is needed as there is currently no way for the core driver to query
the wakeup setting of the glue device, but it is the core driver that
manages the PHY power state during suspend.
Also don't leave the PHYs enabled when system wakeup has been disabled
through sysfs.

A recent commit implementing wakeup support in host mode instead broke
suspend for peripheral and OTG mode.
The hack that was added in the suspend path to determine the speed of
any device connected to the USB2 bus not only accesses internal driver
data for a child device, but also dereferences a NULL pointer or
accesses freed data when the controller is not acting as host.
There's no quick fix to the layering violation, but since reverting
would leave us with broken suspend in host mode with wakeup triggering
immediately, let's keep the hack for now.
Fix the immediate issues by only checking the host bus speed and
enabling wakeup interrupts when acting as host.

The Qualcomm dwc3 runtime-PM implementation checks the xhci
platform-device pointer in the wakeup-interrupt handler to determine
whether the controller is in host mode and if so triggers a resume.
After a role switch in OTG mode the xhci platform-device would have been
freed and the next wakeup from runtime suspend would access the freed
memory.
Note that role switching is executed from a freezable workqueue, which
guarantees that the pointer is stable during suspend.
Also note that runtime PM has been broken since commit 2664deb093
("usb: dwc3: qcom: Honor wakeup enabled/disabled state"), which
incidentally also prevents this issue from being triggered.

This reverts commit d9be8d5c5b.
Generic power-domain flags must be set before the power-domain is
initialised and must specifically not be modified by drivers for devices
that happen to be in the domain.
To make sure that USB power-domains are left enabled during system
suspend when a device in the domain is in the wakeup path, the
GENPD_FLAG_ACTIVE_WAKEUP flag should instead be set for the domain
unconditionally when it is registered.
Note that this also avoids keeping power-domains on during suspend when
wakeup has not been enabled (e.g. through sysfs).
For the runtime PM case, making sure that the PHYs are not suspended and
that they are in the same domain as the controller prevents the domain
from being suspended. If there are cases where this is not possible or
desirable, the genpd implementation may need to be extended.

Enable multipage folio support for the afs filesystem.
Support has already been implemented in netfslib, fscache and cachefiles
and in most of afs, but I've waited for Matthew Wilcox's latest folio
changes.
Note that it does require a change to afs_write_begin() to return the
correct subpage. This is a "temporary" change as we're working on
getting rid of the need for ->write_begin() and ->write_end()
completely, at least as far as network filesystems are concerned - but
it doesn't prevent afs from making use of the capability.

- Error handling fix for passthru (Anuj)
- Remove randomization of struct kiocb fields, to avoid it growing in
size if re-arranged in such a fashion that it grows more holes or
padding (Keith, Linus)
- Small series improving type safety of the sqe fields (Stefan)
* tag 'io_uring-6.0-2022-08-13' of git://git.kernel.dk/linux-block:
io_uring: add missing BUILD_BUG_ON() checks for new io_uring_sqe fields
io_uring: make io_kiocb_to_cmd() typesafe
fs: don't randomize struct kiocb fields
io_uring: consistently make use of io_notif_to_data()
io_uring: fix error handling for io_uring_cmd
io_uring: fix io_recvmsg_prep_multishot sparse warnings
io_uring/net: send retry for zerocopy
io_uring: mem-account pbuf buckets
audit, io_uring, io-wq: Fix memory leak in io_sq_thread() and io_wqe_worker()
io_uring: pass correct parameters to io_req_set_res
This is a prelude to adding more tests to shell tests and in order to
support putting those tests into subdirectories, I need to change the
test code that scans/finds and runs them.
To support subdirs I have to recurse so it's time to refactor the code
to allow this and centralize the shell script finding into one location
and only one single scan that builds a list of all the found tests in
memory instead of it being duplicated in 3 places.
This code also optimizes things like knowing the max width of desciption
strings (as we can do that while we scan instead of a whole new pass of
opening files).
It also more cleanly filters scripts to see only *.sh files thus
skipping random other files in directories like *~ backup files, other
random junk/data files that may appear and the scripts must be
executable to make the cut (this ensures the script lib dir is not seen
as scripts to run).
This avoids perf test running previous older versions of test scripts
that are editor backup files as well as skipping perf.data files that
may appear and so on.
