I started looking at the history of this driver, and last time the
maintainer was active on the mailing list was when discussing how to
remove it. This was in 2012:
https://lore.kernel.org/lkml/4F4DE175.30002@melware.de/
It looks to me like this has in practice been an orphan for quite a while.
It's throwing warnings about stack size in a function that is in dire
need of refactoring, and it's probably a case of "it's time to call it".

This is an effort to disentangle the include/linux/compiler*.h headers
and bring them up to date.
The main idea behind the series is to use feature checking macros
(i.e. __has_attribute) instead of compiler version checks (e.g. GCC_VERSION),
which are compiler-agnostic (so they can be shared, reducing the size
of compiler-specific headers) and version-agnostic.
Other related improvements have been performed in the headers as well,
which on top of the use of __has_attribute it has amounted to a significant
simplification of these headers (e.g. GCC_VERSION is now only guarding
a few non-attribute macros).
This series should also help the efforts to support compiling the kernel
with clang and icc. A fair amount of documentation and comments have also
been added, clarified or removed; and the headers are now more readable,
which should help kernel developers in general.
The series was triggered due to the move to gcc >= 4.6. In turn, this series
has also triggered Sparse to gain the ability to recognize __has_attribute
on its own.
Finally, the __nonstring variable attribute series has been also applied
on top; plus two related patches from Nick Desaulniers for unreachable()
that came a bit afterwards.

Pull new experimental media request API from Mauro Carvalho Chehab:
"A new media request API
This API is needed to support device drivers that can dynamically
change their parameters for each new frame. The latest versions of
Google camera and codec HAL depends on such feature.
At this stage, it supports only stateless codecs.
It has been discussed for a long time (at least over the last 3-4
years), and we finally reached to something that seem to work.
This series contain both the API and core changes required to support
it and a new m2m decoder driver (cedrus).
As the current API is still experimental, the only real driver using
it (cedrus) was added at staging[1]. We intend to keep it there for a
while, in order to test the API. Only when we're sure that this API
works for other cases (like encoders), we'll move this driver out of
staging and set the API into a stone.
[1] We added support for the vivid virtual driver (used only for
testing) to it too, as it makes easier to test the API for the ones
that don't have the cedrus hardware"

I want to sort out support for tinydrm in vc4, so I needed to get a
tinydrm-appropriate panel working and this is what I had on hand.
This is derived from a combination of ili9341.c from tinydrm and
fb_hx8357d.c from staging's fbtft.
v2: Write my own register defs from the spec to not need the header
from fbtft. Fix spi device string to enable module autoloading.

- Vladimir Zapolskiy takes over the LPC18xx platform from Joachim Eastwood
- Manivannan Sadhasivam becomes a secondary maintainer for the

Thanks everyone for working on this, and welcome to the new maintainers!
The "virt" platform on qemy or kvm can now be used in big-endian mode
without additional tricks, thanks to Jason Donenfeld.
Once again, we gain support for another NXP i.MX6 variant, this time

On arm64, we add support for two SoCs from Renesas: RZ/G2E (r8a774c0)
and RZ/G2M (r8a774a1). These are described as microcontrollers on the
manufacturer website, but appear to be rather powerful. The RZ/G2M is

The most noteworthy SoC driver changes this time include:
- The TEE subsystem gains an in-kernel interface to access the TEE
from device drivers.
- The reset controller subsystem gains a driver for the Qualcomm
Snapdragon 845 Power Domain Controller.
- The Xilinx Zynq platform now has a firmware interface for its
platform management unit. This contains a firmware "ioctl" interface
that was a little controversial at first, but the version we merged
solved that by not exposing arbitrary firmware calls to user space.
- The Amlogic Meson platform gains a "canvas" driver that is used
for video processing and shared between different high-level drivers.
The rest is more of the usual, mostly related to SoC specific power
management support and core drivers in drivers/soc:
- Several Renesas SoCs (RZ/G1N, RZ/G2M, R-Car V3M, RZ/A2M) gain new
features related to power and reset control.
- The Mediatek mt8183 and mt6765 SoC platforms gain support for
their respective power management chips.
- A new driver for NXP i.MX8, which need a firmware interface for
power management.
- The SCPI firmware interface now contains support estimating power
usage of performance states
- The NVIDIA Tegra "pmc" driver gains a few new features, in particular
a pinctrl interface for configuring the pads.
- Lots of small changes for Qualcomm, in particular the "smem"
device driver.
- Some cleanups for the TI OMAP series related to their sysc
controller.
Additional cleanups and bugfixes in SoC specific drivers include the
Meson, Keystone, NXP, AT91, Sunxi, Actions, and Tegra platforms.

Here is the big staging and IIO driver pull request for 4.20-rc1.
There are lots of things here, we ended up adding more lines than
removing, thanks to a large influx of Comedi National Instrument device
support. Someday soon we need to get comedi out of staging...
Other than the comedi drivers, the "big" things here are:
- new iio drivers
- delete dgnc driver (no one used it and no one had the hardware
anymore)
- vbox driver updates and fixes
- erofs fixes
- tons and tons of tiny checkpatch fixes for almost all staging
drivers
All of these have been in linux-next, with the last few happening a bit
"late" due to them getting stuck on my laptop during travel to the
Mantainers summit.

Merge tag 'staging-4.20-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging
Pull staging/IIO driver updates from Greg KH:
"Here is the big staging and IIO driver pull request for 4.20-rc1.
There are lots of things here, we ended up adding more lines than
removing, thanks to a large influx of Comedi National Instrument
device support. Someday soon we need to get comedi out of staging...
Other than the comedi drivers, the "big" things here are:
- new iio drivers
- delete dgnc driver (no one used it and no one had the hardware
anymore)
- vbox driver updates and fixes
- erofs fixes
- tons and tons of tiny checkpatch fixes for almost all staging
drivers
All of these have been in linux-next, with the last few happening a
bit "late" due to them getting stuck on my laptop during travel to the
Mantainers summit"

Arnd acks, and adds the following notes:
"I did a thorough review of the ABI, which as usual mainly consists of
spotting any files that don't use the asm-generic ABI itself, and
having it changed to it matches exactly what we do on other new
architectures.
I also looked at every other patch and commented on maybe half of them
where I saw something that did not quite seem right. Others have
reviewed specific patches in greater depth. I'm sure that one could
fine more of the minor details, but as long as they are not ABI
relevant, they can be fixed later.
The only patch that is part of the ABI and that nobody reviewed is the
signal handling. This is one of the areas I never worked on in much
detail. I did not see anything wrong with it, but I also don't know
what the problems with the other architectures are here, and we seem
to be hitting issues occasionally, and we never managed to generalize
this enough for new architectures to have a trivial implementation.
I was originally hoping that we could have the 64-bit time_t
interfaces ready in time to completely drop the 32-bit ones, but that
did not happen. We might still remove them in the next merge window
depending on whether the libc upstream people prefer to keep them or
not.
One more general comment: I think this may well be the last new CPU
architecture we ever add to the kernel. Both nds32 and c-sky are made
by companies that also work on risc-v, and generally speaking risc-v
seems to be killing off any of the minor licensable instruction set
projects, just like ARM has mostly killed off the custom
vendor-specific instruction sets already.
If we add another architecture in the future, it may instead be
something like the LLVM bitcode or WebAssembly, who knows?"
To which Geert Uytterhoeven pipes in about another architecture still in
the pipeline: Kalray MPPA.

The Image Signal Processor found on Cherry Trail devices is brought up in
D0 state on devices which have camera sensors attached to it. The ISP will
not enter D3 state again without some massaging of its registers beforehand
and the ISP not being in D3 state blocks the SoC from entering S0ix modes.
There was a driver for the ISP in drivers/staging but that got removed
again because it never worked. It does not seem likely that a real
driver for the ISP will be added to the mainline kernel anytime soon.
This commit adds a dummy driver which contains the necessary magic from
the staging driver to powerdown the ISP, so that Cherry Trail devices where
the ISP is used will properly use S0ix modes when suspended.
Together with other recent S0ix related fixes this allows S0ix modes to
be entered on e.g. a Chuwi Hi8 Pro and a HP x2 210.

Pull XArray conversion from Matthew Wilcox:
"The XArray provides an improved interface to the radix tree data
structure, providing locking as part of the API, specifying GFP flags
at allocation time, eliminating preloading, less re-walking the tree,
more efficient iterations and not exposing RCU-protected pointers to
its users.
This patch set
1. Introduces the XArray implementation
2. Converts the pagecache to use it
3. Converts memremap to use it
The page cache is the most complex and important user of the radix
tree, so converting it was most important. Converting the memremap
code removes the only other user of the multiorder code, which allows
us to remove the radix tree code that supported it.
I have 40+ followup patches to convert many other users of the radix
tree over to the XArray, but I'd like to get this part in first. The
other conversions haven't been in linux-next and aren't suitable for
applying yet, but you can see them in the xarray-conv branch if you're
interested"

There have been little changes in ALSA core stuff, but ASoC core still
kept rolling for the continued restructuring. The rest are lots of
small driver-specific changes and some minor API updates.
Here are highlights:
General:
- Appropriate fall-through annotations everywhere
- Some code cleanup in memalloc code, handling non-cacahed pages more
commonly in the helper
- Deployment of SNDRV_PCM_INFO_SYNC_APPLPTR flag consistently
Drivers:
- More HD-audio CA0132 codec improvement for supporting other Creative
boards
- Plumbing legacy HD-audio codecs as ASoC BE on Intel SST; this will
give move support of existing HD-audio devices with DSP
- A few device-specific HD-audio quirks as usual
- New quirk for RME CC devices and correction for B&W PX for USB-audio
- FireWire: code refactoring including devres usages
ASoC Core:
- Continued componentization works; it's almost done!
- A bunch of new for_each_foo macros
- Cleanups and fixes in DAPM code
ASoC Drivers:
- MCLK support for several different devices, including CS42L51, STM32
SAI, and MAX98373
- Support for Allwinner A64 CODEC analog, Intel boards with DA7219 and
MAX98927, Meson AXG PDM inputs, Nuvoton NAU8822, Renesas R8A7744 and
TI PCM3060

small updates to the target subsystem a set of conversions to the
generic DMA API, which do have some potential for issues in the older
drivers but we'll handle those as case by case fixes. A new myrs for
the DAC960/mylex raid controllers to replace the block based DAC960

There are few Intel MFD PMIC device drivers which I would like
to review.
Note, Intel MSIC is old system controller that based mostly on PMIC
integrated in it. Thus, I included it as well.

Core changes:
- A patch series from Hans Verkuil to make it possible to
enable/disable IRQs on a GPIO line at runtime and drive GPIO
lines as output without having to put/get them from scratch.
The irqchip callbacks have been improved so that they can
use only the fastpatch callbacks to enable/disable irqs
like any normal irqchip, especially the gpiod_lock_as_irq()
has been improved to be callable in fastpath context.
A bunch of rework had to be done to achieve this but it is
a big win since I never liked to restrict this to slowpath.
The only call requireing slowpath was try_module_get() and
this is kept at the .request_resources() slowpath callback.
In the GPIO CEC driver this is a big win sine a single
line is used for both outgoing and incoming traffic, and
this needs to use IRQs for incoming traffic while actively
driving the line for outgoing traffic.
- Janusz Krzysztofik improved the GPIO array API to pass a
"cookie" (struct gpio_array) and a bitmap for setting or
getting multiple GPIO lines at once. This improvement
orginated in a specific need to speed up an OMAP1 driver and
has led to a much better API and real performance gains
when the state of the array can be used to bypass a lot
of checks and code when we want things to go really fast.
The previous code would minimize the number of calls
down to the driver callbacks assuming the CPU speed was
orders of magnitude faster than the I/O latency, but this
assumption was wrong on several platforms: what we needed
to do was to profile and improve the speed on the hot
path of the array functions and this change is now
completed.
- Clean out the painful and hard to grasp BNF experiments
from the device tree bindings. Future approaches are looking
into using JSON schema for this purpose. (Rob Herring
is floating a patch series.)
New drivers:
- The RCAR driver now supports r8a774a1 (RZ/G2M).
- Synopsys GPIO via CREGs driver.
Major improvements:
- Modernization of the EP93xx driver to use irqdomain and
other contemporary concepts.
- The ingenic driver has been merged into the Ingenic pin
control driver and removed from the GPIO subsystem.
- Debounce support in the ftgpio010 driver.

Intel Wired LAN Doc Updates 2018-10-18
This series contains documentation fixes and updates for Intel wired
LAN drivers.
The following was done:
- Updated incorrect URLs
- removed document references which did not apply to the current
in-kernel drivers
- added documentation for fm10k driver
- added missing documentation on existing or new features
- added SPDX headers to all the documentation files
Lastly, the documentation was converted over to the RST (reStructured
Text) format, so that 'make htmldocs' produces pretty html driver
documentation for our drivers.
====================
Signed-off-by: David S. Miller <davem@davemloft.net>
Now that the documents have been updated to conform to the reStructured Text
guidelines, we can now change the file extensions and update the other

Add support for the DEC FDDIcontroller 700 (DEFZA), Digital Equipment
Corporation's first-generation FDDI network interface adapter, made for
TURBOchannel and based on a discrete version of what eventually became
Motorola's widely used CAMEL chipset.
The CAMEL chipset is present for example in the DEC FDDIcontroller
TURBOchannel, EISA and PCI adapters (DEFTA/DEFEA/DEFPA) that we support
with the `defxx' driver, however the host bus interface logic and the
firmware API are different in the DEFZA and hence a separate driver is
required.
There isn't much to say about the driver except that it works, but there
is one peculiarity to mention. The adapter implements two Tx/Rx queue
pairs.
Of these one pair is the usual network Tx/Rx queue pair, in this case
used by the adapter to exchange frames with the ring, via the RMC (Ring
Memory Controller) chip. The Tx queue is handled directly by the RMC
chip and resides in onboard packet memory. The Rx queue is maintained
via DMA in host memory by adapter's firmware copying received data
stored by the RMC in onboard packet memory.
The other pair is used to communicate SMT frames with adapter's
firmware. Any SMT frame received from the RMC via the Rx queue must be
queued back by the driver to the SMT Rx queue for the firmware to
process. Similarly the firmware uses the SMT Tx queue to supply the
driver with SMT frames that must be queued back to the Tx queue for the
RMC to send to the ring.
This solution was chosen because the designers ran out of PCB space and
could not squeeze in more logic onto the board that would be required to
handle this SMT frame traffic without the need to involve the driver, as
with the later DEFTA/DEFEA/DEFPA adapters.
Finally the driver does some Frame Control byte decoding, so to avoid
magic numbers some macros are added to <linux/if_fddi.h>.

Trace events are useful for people who collect data from the
Ftrace outputs. There're people who analyse the relationship
of cpufreq, thermal and hwmon (power/voltage/current) using
the convenient and timestamped Ftrace outputs, while unlike
cpufreq and thermal subsystems the hwmon does not have trace
events supported yet.
So this patch adds initial trace events for the hwmon core.
To call hwmon_attr_base() for aligned attr index numbers, it
also moves the function upward.
Ftrace outputs:
...: hwmon_attr_show_string: index=2, attr_name=in2_label, val=VDD_5V
...: hwmon_attr_show: index=2, attr_name=in2_input, val=5112
...: hwmon_attr_show: index=2, attr_name=curr2_input, val=440
Note that the _attr_show and _attr_store functions are tied
to the _with_info API. So a hwmon driver requiring the trace
events feature should use _with_info API to register a hwmon
device.

LPC18xx/LPC43xx archtecture about two years ago, and for me it would be
possible to continue the support, fortunately the quality of platform
drivers written by Joachim is exceptionally high.
The change is based on https://lkml.org/lkml/2018/9/24/1398 discussion.
At the same time two redundant explicit driver file paths are dropped
from the list, clk-lpc18xx* drivers are covered by "lpc18xx" search
pattern and timer-lpc32xx driver is covered by "lpc32xx" pattern and it
goes into ARM/LPC32XX entry, which is also under my wing, in other words
LPC18xx/LPC43xx clocksource and CCF drivers will remain maintained.

Here is another TMIO MMC variant found in Socionext UniPhier SoCs.
As commit b6147490e6 ("mmc: tmio: split core functionality, DMA and
MFD glue") said, these MMC controllers use the IP from Panasonic.
However, the MMC controller in the TMIO (Toshiba Mobile IO) MFD chip
was the first upstreamed user of this IP. The common driver code
for this IP is now called 'tmio-mmc-core' in Linux although it is a
historical misnomer.
Anyway, this driver select's MMC_TMIO_CORE to borrow the common code
from tmio-mmc-core.c
Older UniPhier SoCs (LD4, Pro4, sLD8) support the external DMA engine
like renesas_sdhi_sys_dmac.c. The difference is UniPhier SoCs use a
single DMA channel whereas Renesas chips request separate channels for
RX and TX.
Newer UniPhier SoCs (Pro5 and later) support the internal DMA engine
like renesas_sdhi_internal_dmac.c The register map is almost the same,
so I guess Renesas and Socionext use the same internal DMA hardware.
The main difference is, the register offsets are doubled for Renesas.
Renesas Socionext
SDHI UniPhier
DM_CM_DTRAN_MODE 0x820 0x410
DM_CM_DTRAN_CTRL 0x828 0x414
DM_CM_RST 0x830 0x418
DM_CM_INFO1 0x840 0x420
DM_CM_INFO1_MASK 0x848 0x424
DM_CM_INFO2 0x850 0x428
DM_CM_INFO2_MASK 0x858 0x42c
DM_DTRAN_ADDR 0x880 0x440
DM_DTRAN_ADDREX --- 0x444
This comes from the difference of host->bus_shift; 2 for Renesas SoCs,
and 1 for UniPhier SoCs. Also, the datasheet for UniPhier SoCs defines
DM_DTRAN_ADDR and DM_DTRAN_ADDREX as two separate registers.
It could be possible to factor out the DMA common code by introducing
some hooks to cope with platform quirks, but this patch does not touch
that for now.

Berlin SoC files has been moved from marvell dir to synaptics dir, but
commit bc52497a59 ("MAINTAINERS: update entry for ARM/berlin") didn't
update the dir accordingly. This patch fixes it.
From another side, new derivative SoCs from Synaptics may not be named

One merge commit in here to bring in the SPI_CS_WORD flag patches
that are also going via the SPI tree.
There are a few more fixes than normal for a pull targetting the
next merge window. These are all long term issues and as we are late
in the cycle, they can wait.
New device support
* ad7606
- Add support fo the ad7605-4 driver. This driver is still in staging
but is heading in the right direction to graduate, motivated partly
by the requirement for this device support.
* ST VL53L0X ToF ranging sensor
- New minimal driver. Interrupt support to follow.
New features
* SPI_CS_WORD optimization allows long transfers with the chip select
toggled every 16bits. There is a software fallback as well to let
drivers not care about whether the hardware supports it.
* bh1750
- Device tree support and bindings.
* ti-ads7950
- Use the SPI_CS_WORD optmization to save lots of cpu cycles (assuming
the hardware supports it)
Fixes and cleanups
* ad5064
- Fix some long incorrect regulator error handling that preventing
enabling the internal regulator.
* ad7606
- The ad7606 doesn't actually have a 2.5V range and the values provided
for scale have always been wrong. Fix them.
- Drop some wrong kernel-doc (things that don't exist)
- Add missing kernel-doc
* at91-adc
- Fixing missing ack of dataready on sysfs channel reads to avoid spurious
interrupts.
- Fix a wrong channel numbers in triggered_buffer_mode
* hmc5843
- Fix incorrect part number in a comment.
* imx25-gcq
- Fix a device_node leak in an error path.
* meson-saradc
- Drop an unused and pointless define.
- Use of_device_get_match_data instead of opencoding
- Tidy up how meson_sar_adc_param is accessed.
- Rework prior to adding some temperature sensor support.

Prior to 256a459370 ("PCI/AER: Squash aerdrv_acpi.c into aerdrv.c"),
drivers/pci/pcie/aer/aerdrv_acpi.c contained code to parse the ACPI HEST
table. That code now lives in drivers/pci/pcie/aer.c.
Remove the "F: drivers/pci/*/*/*acpi*" pattern because it matches nothing.
We could add a "F: drivers/pci/pcie/aer.c" pattern to the ACPI APEI
section, but that file sees a lot of changes, almost none of which are of

With this I assume maintainership of the Integrator, Versatile

It's no big secret that I've been maintaining them for years,
but might as well make it official so I get the mails and
don't miss anything.
I have also included some drivers that are closely associated
with the ARM reference designs and yet orphaned in the
MAINTAINERS file. I can surely maintain them too, or route
the question to the right people so it doesn't fall on the
floor of upward to the subsystem maintainers who have too much
to do already as it is.

Registers the matrix device created by the VFIO AP device
driver with the VFIO mediated device framework.
Registering the matrix device will create the sysfs
structures needed to create mediated matrix devices
each of which will be used to configure the AP matrix
for a guest and connect it to the VFIO AP device driver.
Registering the matrix device with the VFIO mediated device
framework will create the following sysfs structures:
/sys/devices/vfio_ap/matrix/
...... [mdev_supported_types]
......... [vfio_ap-passthrough]
............ create
To create a mediated device for the AP matrix device, write a UUID
to the create file:
uuidgen > create
A symbolic link to the mediated device's directory will be created in the
devices subdirectory named after the generated $uuid:
/sys/devices/vfio_ap/matrix/
...... [mdev_supported_types]
......... [vfio_ap-passthrough]
............ [devices]
............... [$uuid]
A symbolic link to the mediated device will also be created
in the vfio_ap matrix's directory:

Introduces a new AP device driver. This device driver
is built on the VFIO mediated device framework. The framework
provides sysfs interfaces that facilitate passthrough
access by guests to devices installed on the linux host.
The VFIO AP device driver will serve two purposes:
1. Provide the interfaces to reserve AP devices for exclusive
use by KVM guests. This is accomplished by unbinding the
devices to be reserved for guest usage from the zcrypt
device driver and binding them to the VFIO AP device driver.
2. Implements the functions, callbacks and sysfs attribute
interfaces required to create one or more VFIO mediated
devices each of which will be used to configure the AP
matrix for a guest and serve as a file descriptor
for facilitating communication between QEMU and the
VFIO AP device driver.
When the VFIO AP device driver is initialized:
* It registers with the AP bus for control of type 10 (CEX4
and newer) AP queue devices. This limitation was imposed
due to:
1. A desire to keep the code as simple as possible;
2. Some older models are no longer supported by the kernel
and others are getting close to end of service.
3. A lack of older systems on which to test older devices.
The probe and remove callbacks will be provided to support
the binding/unbinding of AP queue devices to/from the VFIO
AP device driver.
* Creates a matrix device, /sys/devices/vfio_ap/matrix,
to serve as the parent of the mediated devices created, one
for each guest, and to hold the APQNs of the AP devices bound to
the VFIO AP device driver.

This introduces the Cedrus VPU driver that supports the VPU found in
Allwinner SoCs, also known as Video Engine. It is implemented through
a V4L2 M2M decoder device and a media device (used for media requests).
So far, it only supports MPEG-2 decoding.
Since this VPU is stateless, synchronization with media requests is
required in order to ensure consistency between frame headers that
contain metadata about the frame to process and the raw slice data that
is used to generate the frame.
This driver was made possible thanks to the long-standing effort
carried out by the linux-sunxi community in the interest of reverse
engineering, documenting and implementing support for the Allwinner VPU.

"A set of fixes for x86:

during early boot results in encrypted storage, which is not

which is mapped unencrypted and take care that the later
allocations for shared kvmclock memory is unencrypted as well.
- Fix the build regression in the paravirt code introduced by the
recent spectre v2 updates.
- Ensure that the initial static page tables cover the fixmap space
correctly so early console always works. This worked so far by
chance, but recent modifications to the fixmap layout can -
depending on kernel configuration - move the relevant entries to a

we also put the driver on a severe diet due to how much of the
code was unneeded or was unused. The outcome is a lean and mean
virtual function driver that continues to work on existing 40GbE
(i40e) virtual devices and prepped for future supported devices,
like the 100GbE (ice) virtual devices.
This solves 2 issues we saw coming or were already present, the
first was constant code duplication happening with i40e/i40evf,
when much of the duplicate code in the i40evf was not used or was
not needed. The second was to remove the future confusion of why
future VF devices that were not considered "40GbE" only devices
were supported by i40evf.
The thought is that iavf will be the virtual function driver for
all future devices, so it should have a "generic" name to properly
represent that it is the VF driver for multiple generations of
devices.
The last patch in this series is unreleated to the iavf conversion
and just has to do with a MODULE_LICENSE correction.
Known Caveats:
Existing user space configurations may have to change, but the module
alias in patch 1 helps a bit here.

The original PCI error recovery functionality was for the powerpc-specific
IBM EEH feature. PCIe subsequently added some similar features, including
AER and DPC, that can be used on any architecture.
We want the generic PCI core error handling support to work with all of
these features. Driver error recovery callbacks should be independent of
which feature the platform provides.
Add the generic PCI core error recovery files to the powerpc EEH
MAINTAINERS entry so the powerpc folks will be copied on changes to the
generic PCI error handling strategy.
Add Sam and Oliver as maintainers for this area.

Rename the Intel Ethernet Adaptive Virtual Function driver
(i40evf) to a new name (iavf) that is more consistent with
the ongoing maintenance of the driver as the universal VF driver
for multiple product lines.
This first patch fixes up the directory names and the .ko name,
intentionally ignoring the function names inside the driver
for now. Basically this is the simplest patch that gets
the rename done and will be followed by other patches that
rename the internal functions.
This patch also addresses a couple of string/name issues
and updates the Copyright year.
Also, made sure to add a MODULE_ALIAS to the old name.

ASoC: Fixes for v4.19
This is the usual set of small fixes scatterd around various drivers,
plus one fix for DAPM and a UAPI build fix. There's not a huge amount
that stands out here relative to anything else.
Here are a few small staging and iio driver fixes for -rc4.
Nothing major, just a few small bugfixes for some reported issues, and a
MAINTAINERS file update for the fbtft drivers. We also re-enable the
building of the erofs filesystem as the patcheset that was causing it to
break never got merged in the -rc1 cycle, so there's no reason it can't
be turned back on for now. The problem that was previously there is now
being handled in that other tree at the moment, so it will not hit us
again in the future.
All of these patches have been in linux-next with no reported issues.

This adds the DSA driver for the GSWIP Switch found in the VRX200 SoC.
This switch is integrated in the DSL SoC, this SoC uses a GSWIP version
2.1, there are other SoCs using different versions of this IP block, but
this driver was only tested with the version found in the VRX200.
Currently only the basic features are implemented which will forward all
packages to the CPU and let the CPU do the forwarding. The hardware also
support Layer 2 offloading which is not yet implemented in this driver.
The GPHY FW loaded is now done by this driver and not any more by the
separate driver in drivers/soc/lantiq/gphy.c, I will remove this driver
is a separate patch. to make use of the GPHY this switch driver is
needed anyway. Other SoCs have more embedded GPHYs so this driver should
support a variable number of GPHYs. After the firmware was loaded the
GPHY can be probed on the MDIO bus and it behaves like an external GPHY,
without the firmware it can not be probed on the MDIO bus.
The clock names in the sysctrl.c file have to be changed because the
clocks are now used by a different driver. This should be cleaned up and
a real common clock driver should provide the clocks instead.

This drives the PMAC between the GSWIP Switch and the CPU in the VRX200
SoC. This is currently only the very basic version of the Ethernet
driver.
When the DMA channel is activated we receive some packets which were
send to the SoC while it was still in U-Boot, these packets have the
wrong header. Resetting the IP cores did not work so we read out the
extra packets at the beginning and discard them.
This also adapts the clock code in sysctrl.c to use the default name of
the device node so that the driver gets the correct clock. sysctrl.c
should be replaced with a proper common clock driver later.

This handles the tag added by the PMAC on the VRX200 SoC line.
The GSWIP uses internally a GSWIP special tag which is located after the
Ethernet header. The PMAC which connects the GSWIP to the CPU converts
this special tag used by the GSWIP into the PMAC special tag which is
added in front of the Ethernet header.
This was tested with GSWIP 2.1 found in the VRX200 SoCs, other GSWIP
versions use slightly different PMAC special tags.

We recently had to debug a TLB invalidation problem on the munmap()
path, which was made more difficult than necessary because:
(a) The MMU gather code had changed without people realising
(b) Many people subtly misunderstood the operation of the MMU gather
code and its interactions with RCU and arch-specific TLB invalidation
(c) Untangling the intended behaviour involved educated guesswork and
plenty of discussion
Hopefully, we can avoid getting into this mess again by designating a
cross-arch group of people to look after this code. It is not intended
that they will have a separate tree, but they at least provide a point
of contact for anybody working in this area and can co-ordinate any
proposed future changes to the internal API.
