The remove path in xhci platform driver tries to remove and put both main
and shared hcds even if only a main hcd exists (one roothub)

This causes a null pointer dereference in reboot for those controllers.

Check that the shared_hcd exists before trying to remove it.

The recent commit 87d0e2f4 ("usb: typec: ucsi: add a common
function ucsi_unregister_connectors()") introduced a regression that
caused NULL dereference at reading the power supply sysfs.  It's a
stale sysfs entry that should have been removed but remains with NULL
ops.  The commit changed the error handling to skip the entries after
a NULL con->wq, and this leaves the power device unreleased.

For addressing the regression, the straight revert is applied here.
Further code improvements can be done from the scratch again.

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.

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 2664deb0
("usb: dwc3: qcom: Honor wakeup enabled/disabled state"), which
incidentally also prevents this issue from being triggered.

This reverts commit d9be8d5c.

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.

Turning on NOP_USB_XCEIV as builtin broke the TUSB6010 driver because
of an older issue with the depencency.

It is not necessary to forbid NOP_USB_XCEIV=y in combination with
USB_MUSB_HDRC=m, but only the reverse, which causes the link failure
from the original Kconfig change.

Use the correct dependency to still allow NOP_USB_XCEIV=n or
NOP_USB_XCEIV=y but forbid NOP_USB_XCEIV=m when USB_MUSB_HDRC=m
to fix the multi_v7_defconfig for tusb.

Only Thunderbolt 3 routers need the xHCI connection flow. This also
ensures the router actually has both lane adapters (1 and 3). While
there move declaration of the boolean variables inside the block where
they are being used.

 - 'perf c2c' now supports ARM64, adjust its output to cope with
   differences with what is in x86_64. Now go find false sharing on
   ARM64 (at least Neoverse) as well!

 - Refactor the JSON processing, making the output more compact and thus
   reducing the size of the resulting perf binary

 - Improvements for 'perf offcpu' profiling, including tracking child
   processes

 - Update Intel JSON metrics and events files for broadwellde,
   broadwellx, cascadelakex, haswellx, icelakex, ivytown, jaketown,
   knightslanding, sapphirerapids, skylakex and snowridgex

 - Add 'perf stat' JSON output and a 'perf test' entry for it

 - Ignore memfd and anonymous mmap events if jitdump present

 - Refactor 'perf test' shell tests allowing subdirs

 - Fix an error handling path in 'parse_perf_probe_command()'

 - Fixes for the guest Intel PT tracing patchkit in the 1st batch of
   this merge window

 - Print debuginfod queries if -v option is used, to explain delays in
   processing when debuginfo servers are enabled to fetch DSOs with
   richer symbol tables

 - Improve error message for 'perf record -p not_existing_pid'

 - Fix openssl and libbpf feature detection

 - Add PMU pai_crypto event description for IBM z16 on 'perf list'

Pull powerpc fixes from Michael Ellerman:

 - Ensure we never emit lwarx with EH=1 on 32-bit, because some 32-bit
   CPUs trap on it rather than ignoring it as they should.

 - Fix ftrace when building with clang, which was broken by some
   refactoring.

 - A couple of other minor fixes.

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.
