This is actually a subsystem description, with contains both
kAPI and uAPI.
While it should ideally be slplit, let's place it at driver-api,
as most things are related to kAPI and driver-specific info.

Pull driver core and debugfs updates from Greg KH:
"Here is the "big" driver core and debugfs changes for 5.3-rc1
It's a lot of different patches, all across the tree due to some api
changes and lots of debugfs cleanups.
Other than the debugfs cleanups, in this set of changes we have:
- bus iteration function cleanups
- scripts/get_abi.pl tool to display and parse Documentation/ABI
entries in a simple way
- cleanups to Documenatation/ABI/ entries to make them parse easier
due to typos and other minor things
- default_attrs use for some ktype users
- driver model documentation file conversions to .rst
- compressed firmware file loading
- deferred probe fixes
All of these have been in linux-next for a while, with a bunch of
merge issues that Stephen has been patient with me for"

Pull char / misc driver updates from Greg KH:
"Here is the "large" pull request for char and misc and other assorted
smaller driver subsystems for 5.3-rc1.
It seems that this tree is becoming the funnel point of lots of
smaller driver subsystems, which is fine for me, but that's why it is
getting larger over time and does not just contain stuff under
drivers/char/ and drivers/misc.
Lots of small updates all over the place here from different driver
subsystems:

- A fair pile of RST conversions, many from Mauro. These create more

- A new document on how to use merges and rebases in kernel repos,

- Various improvements to the build system, including automatic
markup of function() references because some people, for reasons I
will never understand, were of the opinion that
:c:func:``function()`` is unattractive and not fun to type.

Pull GPIO updates from Linus Walleij:
"This is the big slew of GPIO changes for the v5.3 kernel cycle. This
is mostly incremental work this time.
Three important things:
- The FMC subsystem is deleted through my tree. This happens through
GPIO as its demise was discussed in relation to a patch decoupling
its GPIO implementation from the standard way of handling GPIO. As
it turns out, that is not the only subsystem it reimplements and
the authors think it is better do scratch it and start over using
the proper kernel subsystems than try to polish the rust shiny. See
the commit (ACKed by the maintainers) for details.
- Arnd made a small devres patch that was ACKed by Greg and goes into
the device core.
- SPDX header change colissions may happen, because at times I've
seen that quite a lot changed during the -rc:s in regards to SPDX.
(It is good stuff, tglx has me convinced, and it is worth the
occasional pain.)
Apart from this is is nothing controversial or problematic.
Summary:
Core:
- When a gpio_chip request GPIOs from itself, it can now fully
control the line characteristics, both machine and consumer flags.
This makes a lot of sense, but took some time before I figured out
that this is how it has to work.
- Several smallish documentation fixes.
New drivers:
- The PCA953x driver now supports the TI TCA9539.
- The DaVinci driver now supports the K3 AM654 SoCs.
Driver improvements:
- Major overhaul and hardening of the OMAP driver by Russell King.
- Starting to move some drivers to the new API passing irq_chip along
with the gpio_chip when adding the gpio_chip instead of adding it
separately.
Unrelated:
- Delete the FMC subsystem"

Pull s390 updates from Vasily Gorbik:
- Improve stop_machine wait logic: replace cpu_relax_yield call in
generic stop_machine function with a weak stop_machine_yield
function. This is overridden on s390, which yields the current cpu to
the neighbouring cpu after a couple of retries, instead of blindly
giving up the cpu to the hipervisor. This significantly improves
stop_machine performance on s390 in overcommitted scenarios.
This includes common code changes which have been Acked by Peter
Zijlstra and Thomas Gleixner.
- Improve jump label transformation speed: transform jump labels
without using stop_machine.
- Refactoring of the vfio-ccw cp handling, simplifying the code and
avoiding unneeded allocating/copying.
- Various vfio-ccw fixes (ccw translation, state machine).
- Add support for vfio-ap queue interrupt control in the guest. This
includes s390 kvm changes which have been Acked by Christian
Borntraeger.
- Add protected virtualization support for virtio-ccw.
- Enforce both CONFIG_SMP and CONFIG_HOTPLUG_CPU, which allows to
remove some code which most likely isn't working at all, besides that
s390 didn't even compile for !CONFIG_SMP.
- Support for special flagged EP11 CPRBs for zcrypt.
- Handle PCI devices with no support for new MIO instructions.
- Avoid KASAN false positives in reworked stack unwinder.
- Couple of fixes for the QDIO layer.
- Convert s390 specific documentation to ReST format.
- Let s390 crypto modules return -ENODEV instead of -EOPNOTSUPP if
hardware is missing. This way our modules behave like most other
modules and which is also what systemd's systemd-modules-load.service
expects.
- Replace defconfig with performance_defconfig, so there is one config
file less to maintain.
- Remove the SCLP call home device driver, which was never useful.
- Cleanups all over the place.

- add blank lines and identation in order to identify paragraphs;
- fix tables markups;
- add some lists markups;
- mark literal blocks;
- adjust title markups.

adding some literal block markups is needed for it to be

While it has a small chapter with sysfs stuff, most of
the document is focused on driver development.
As it describes a kernel API, move it to the driver-api

Pull gpio updates from Linus Walleij:
"This is the bulk of the GPIO changes for the v5.2 kernel cycle. A bit
later than usual because I was ironing out my own mistakes. I'm
holding some stuff back for the next kernel as a result, and this
should be a healthy and well tested batch.
Core changes:
- The gpiolib MMIO driver has been enhanced to handle two direction
registers, i.e. one register to set lines as input and one register
to set lines as output. It turns out some silicon engineer thinks
the ability to configure a line as input and output at the same
time makes sense, this can be debated but includes a lot of analog
electronics reasoning, and the registers are there and need to be
handled consistently. Unsurprisingly, we enforce the lines to be
either inputs or outputs in such schemes.
- Send in the proper argument value to .set_config() dispatched to
the pin control subsystem. Nobody used it before, now someone does,
so fix it to work as expected.
- The ACPI gpiolib portions can now handle pin bias setting (pull up
or pull down). This has been in the ACPI spec for years and we
finally have it properly integrated with Linux GPIOs. It was based
on an observation from Andy Schevchenko that Thomas Petazzoni's
changes to the core for biasing the PCA950x GPIO expander actually
happen to fit hand-in-glove with what the ACPI core needed. Such
nice synergies happen sometimes.
New drivers:
- A new driver for the Mellanox BlueField GPIO controller. This is
using 64bit MMIO registers and can configure lines as inputs and
outputs at the same time and after improving the MMIO library we
handle it just fine. Interesting.
- A new IXP4xx proper gpiochip driver with hierarchical interrupts
should be coming in from the ARM SoC tree as well.
Driver enhancements:
- The PCA053x driver handles the CAT9554 GPIO expander.
- The PCA053x driver handles the NXP PCAL6416 GPIO expander.
- Wake-up support on PCA053x GPIO lines.
- OMAP now does a nice asynchronous IRQ handling on wake-ups by
letting everything wake up on edges, and this makes runtime PM work
as expected too.
Misc:
- Several cleanups such as devres fixes.
- Get rid of some languager comstructs that cause problems when
compiling with LLVMs clang.
- Documentation review and update"

Pull drm updates from Dave Airlie:
"This has two exciting community drivers for ARM Mali accelerators.
Since ARM has never been open source friendly on the GPU side of the
house, the community has had to create open source drivers for the
Mali GPUs. Lima covers the older t4xx and panfrost the newer 6xx/7xx
series. Well done to all involved and hopefully this will help ARM
head in the right direction.
There is also now the ability if you don't have any of the legacy
drivers enabled (pre-KMS) to remove all the pre-KMS support code from
the core drm, this saves 10% or so in codesize on my machine.
i915 also enable Icelake/Elkhart Lake Gen11 GPUs by default, vboxvideo
moves out of staging.
There are also some rcar-du patches which crossover with media tree
but all should be acked by Mauro.

Pull staging / IIO driver updates from Greg KH:
"Here is the big staging and iio driver update for 5.2-rc1.
Lots of tiny fixes all over the staging and IIO driver trees here,
along with some new IIO drivers.
The "counter" subsystem was added in here as well, as it is needed by
the IIO drivers and subsystem.
Also we ended up deleting two drivers, making this pull request remove
a few hundred thousand lines of code, always a nice thing to see. Both
of the drivers removed have been replaced with "real" drivers in their
various subsystem directories, and they will be coming to you from
those locations during this merge window.
There are some core vt/selection changes in here, that was due to some
cleanups needed for the speakup fixes. Those have all been acked by
the various subsystem maintainers (i.e. me), so those are ok.
We also added a few new drivers, for some odd hardware, giving new
developers plenty to work on with basic coding style cleanups to come
in the near future.
Other than that, nothing unusual here.
All of these have been in linux-next for a while with no reported
issues, other than an odd gcc warning for one of the new drivers that
should be fixed up soon"

Pull mmiowb removal from Will Deacon:
"Remove Mysterious Macro Intended to Obscure Weird Behaviours (mmiowb())
Remove mmiowb() from the kernel memory barrier API and instead, for
architectures that need it, hide the barrier inside spin_unlock() when
MMIO has been performed inside the critical section.
The only relatively recent changes have been addressing review
comments on the documentation, which is in a much better shape thanks
to the efforts of Ben and Ingo.
I was initially planning to split this into two pull requests so that
you could run the coccinelle script yourself, however it's been plain
sailing in linux-next so I've just included the whole lot here to keep
things simple"
