The use of PHY_REFCLK_USE_PAD introduced a regression for apq8064 devices.
It was tested that while apq doesn't require the padding, ipq SoC must use
it or the kernel hangs on boot.

Here is the large set of char/misc/whatever driver subsystem updates for
5.12-rc1. Over time it seems like this tree is collecting more and more
tiny driver subsystems in one place, making it easier for those
maintainers, which is why this is getting larger.
Included in here are:
- coresight driver updates
- habannalabs driver updates
- virtual acrn driver addition (proper acks from the x86
maintainers)
- broadcom misc driver addition
- speakup driver updates
- soundwire driver updates
- fpga driver updates
- amba driver updates
- mei driver updates
- vfio driver updates
- greybus driver updates
- nvmeem driver updates
- phy driver updates
- mhi driver updates
- interconnect driver udpates
- fsl-mc bus driver updates
- random driver fix
- some small misc driver updates (rtsx, pvpanic, etc.)
All of these have been in linux-next for a while, with the only reported
issue being a merge conflict in include/linux/mod_devicetable.h that you
will hit in your tree due to the dfl_device_id addition from the fpga
subsystem in here. The resolution should be simple.

Here is the "big" driver core and debugfs update for 5.12-rc1
This set of driver core patches caused a bunch of problems in linux-next
for the past few weeks, when Saravana tried to set fw_devlink=on as the
default functionality. This caused a number of systems to stop booting,
and lots of bugs were fixed in this area for almost all of the reported
systems, but this option is not ready to be turned on just yet for the
default operation based on this testing, so I've reverted that change at
the very end so we don't have to worry about regressions in 5.12. We
will try to turn this on for 5.13 if testing goes better over the next
few months.
Other than the fixes caused by the fw_devlink testing in here, there's
not much more:
- debugfs fixes for invalid input into debugfs_lookup()
- kerneldoc cleanups
- warn message if platform drivers return an error on their
remove callback (a futile effort, but good to catch).
All of these have been in linux-next for a while now, and the
regressions have gone away with the revert of the fw_devlink change.

Introduce an initial driver for CXL 2.0 Type-3 Memory Devices. CXL is
Compute Express Link which released the 2.0 specification in November.
The Linux relevant changes in CXL 2.0 are support for an OS to
dynamically assign address space to memory devices, support for
switches, persistent memory, and hotplug. A Type-3 Memory Device is a
PCI enumerated device presenting the CXL Memory Device Class Code and
implementing the CXL.mem protocol. CXL.mem allows device to advertise
CPU and I/O coherent memory to the system, i.e. typical "System RAM" and
"Persistent Memory" in Linux /proc/iomem terms.
In addition to the CXL.mem fast path there is an administrative command
hardware mailbox interface for maintenance and provisioning. It is this
command interface that is the focus of the initial driver. With this
driver a CXL device that is mapped by the BIOS can be administered by
Linux. Linux support for CXL PMEM and dynamic CXL address space
management are to be implemented post v5.12.

Pull initial support for CXL (Compute Express Link) from Dan Williams:
"Introduce an initial driver for CXL 2.0 Type-3 Memory Devices.
CXL is Compute Express Link which released the 2.0 specification in
November. The Linux relevant changes in CXL 2.0 are support for an OS
to dynamically assign address space to memory devices, support for
switches, persistent memory, and hotplug.
A Type-3 Memory Device is a PCI enumerated device presenting the CXL
Memory Device Class Code and implementing the CXL.mem protocol.
CXL.mem allows device to advertise CPU and I/O coherent memory to the
system, i.e. typical "System RAM" and "Persistent Memory" in Linux
/proc/iomem terms.
In addition to the CXL.mem fast path there is an administrative
command hardware mailbox interface for maintenance and provisioning.
It is this command interface that is the focus of the initial driver.
With this driver a CXL device that is mapped by the BIOS can be
administered by Linux.
Linux support for CXL PMEM and dynamic CXL address space management
are to be implemented post v5.12"

Since commit a0fd361db8 ("PCI: dwc: Move "dbi", "dbi2", and
"addr_space" resource setup into common code"), the code
setting dbi_base when the config space is defined in 'ranges' property
instead of 'reg' is dead code as dbi_base is never NULL.
Rather than fix this, let's just drop the code. Using ranges has been
deprecated since 2014. The only platforms using this were exynos5440,
i.MX6 and Spear13xx. Exynos5440 is dead and has been removed. i.MX6 and
Spear13xx had PCIe support added just before this was deprecated and
were fixed within a kernel release or 2.

In commit 5cf0fd591f ("Kbuild: disable TRIM_UNUSED_KSYMS option") I
disabled this option because it's hugely expensive at build time, and I
questioned how much use it gets.
Several people piped up and convinced me it's actually useful, so
instead of disabling it entirely, it now depends on EXPERT and gets
disabled by COMPILE_TEST builds so that 'allmodconfig' style things
don't enable it.
I still hope somebody will take a look at the build time issue, because
as Arnd also noted:
"However, the combination of thinlto and trim indeed has a steep cost
in compile time, taking almost twice as long as a normal defconfig
(gc-sections makes it slightly faster)"

scripts/kconfig/conf supports -? option to show the help message.
This is not wired up to Makefile, so nobody would notice this, but
it also shows 'invalid option' message.
$ ./scripts/kconfig/conf -?
./scripts/kconfig/conf: invalid option -- '?'
Usage: ./scripts/kconfig/conf [-s] [option] <kconfig-file>
[option] is _one_ of the following:
--listnewconfig List new options
--helpnewconfig List new options and help text
--oldaskconfig Start a new configuration using a line-oriented program
...
The reason is the '?' is missing in the short option list passed to
getopt_long().
While I fixed this issue, I also changed the option '?' to 'h'.
I prefer -h (or --help, if a long option is also desired).

"Here's a set of minor keyrings fixes/cleanups that I've collected from
various people for the upcoming merge window.
A couple of them might, in theory, be visible to userspace:
- Make blacklist_vet_description() reject uppercase letters as they
don't match the all-lowercase hex string generated for a blacklist
search.
This may want reconsideration in the future, but, currently, you
can't add to the blacklist keyring from userspace and the only
source of blacklist keys generates lowercase descriptions.
- Fix blacklist_init() to use a new KEY_ALLOC_* flag to indicate that
it wants KEY_FLAG_KEEP to be set rather than passing KEY_FLAG_KEEP
into keyring_alloc() as KEY_FLAG_KEEP isn't a valid alloc flag.
This isn't currently a problem as the blacklist keyring isn't
currently writable by userspace.
The rest of the patches are cleanups and I don't think they should
