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"

A "real" driver for this hardware is now in the wireless-drivers-next
tree, to be merged in the next major kernel release, so this staging
driver can now be deleted as it is not needed anymore.
Note, 2 .h files remain for this driver, as they are referenced in a
separate staging driver. That mess will be cleaned up in a follow-on
patch.

These drivers have been outside of the kernel tree since the 2.x days,
and it's time to bring them into the tree so they can get properly
cleaned up.
This first dump of drivers is based on a tarball Matt gave to me, minus
an odd "dma" driver that I could not get to build at all. I renamed a
few files, added the proper SPDX lines to it, added Kconfig entries and
tied it into the kernel build. I also fixed up a number of initial
obvious kernel build warnings, but left the odd bitfield warning that
gcc is spitting out, as I'm not quite sure what to do about that.
There's loads of low-hanging coding style cleanups in here for people to
start attacking, as well as the more obvious logic and api cleanups as
well.

Fieldbus device (client) adapters allow data exchange with a PLC aka.
"Fieldbus Controller" over a fieldbus (Profinet, FLNet, etc.)
They are typically used when a Linux device wants to expose itself
as an actuator, motor, console light, switch, etc. over the fieldbus.
This framework is designed to provide a generic interface to Fieldbus
Devices from both the Linux Kernel and the userspace.

'default n' is the default value for any bool or tristate Kconfig
setting so there is no need to write it explicitly.
Also since commit f467c5640c29 ("kconfig: only write '# CONFIG_FOO
is not set' for visible symbols") the Kconfig behavior is the same
regardless of 'default n' being present or not:
...
One side effect of (and the main motivation for) this change is making
the following two definitions behave exactly the same:
config FOO
bool
config FOO
bool
default n
With this change, neither of these will generate a
'# CONFIG_FOO is not set' line (assuming FOO isn't selected/implied).
That might make it clearer to people that a bare 'default n' is
redundant.

The license text in this driver is "interesting" and not really obvious
that it is supposed to be able to be distributed in the kernel source
tree. Yes, the MODULE_LICENSE() text says GPL, so it's probably ok, but
to be safe, I am deleting this driver. I will be glad to add it back if
the license is properly sorted out, but for now, this isn't worth the
potential risk, I should have never taken it in the first place.

This patch moves the MT7621 SPI driver, which is used on some Ralink /
MediaTek MT76xx MIPS SoC's, out of the staging directory. No changes to
the source code are done in this patch.
This driver version was tested successfully on an MT7688 based platform
with an SPI NOR on CS0 and an SPI NAND on CS1 without any issues (so
far).
This patch also documents the devicetree bindings for the MT7621 SPI
device driver.

Pull staging and IIO updates from Greg KH:
"Here are the big staging/iio patches for 4.19-rc1.
Lots of churn here, with tons of cleanups happening in staging
drivers, a removal of an old crypto driver that no one was using
(skein), and the addition of some new IIO drivers. Also added was a
"gasket" driver from Google that needs loads of work and the erofs
filesystem.
Even with adding all of the new drivers and a new filesystem, we are
only adding about 1000 lines overall to the kernel linecount, which
shows just how much cleanup happened, and how big the unused crypto
driver was.
All of these have been in the linux-next tree for a while now with no

This IP core has read and write AXI-Stream FIFOs, the contents of which can
be accessed from the AXI4 memory-mapped interface. This is useful for
transferring data from a processor into the FPGA fabric. The driver creates
a character device that can be read/written to with standard
open/read/write/close.
See Xilinx PG080 document for IP details.

The Gasket (Google ASIC Software, Kernel Extensions, and Tools) kernel
framework is a generic, flexible system that supports thin kernel
drivers. Gasket kernel drivers are expected to handle opening and
closing devices, mmap'ing BAR space as requested, a small selection of
ioctls, and handling page table translation (covered below). Any other
functions should be handled by userspace code.
The Gasket common module is not enough to run a device. In order to
customize the Gasket code for a given piece of hardware, a device
specific module must be created. At a minimum, this module must define a
struct gasket_driver_desc containing the device-specific data for use by
the framework; in addition, the module must declare an __init function
that calls gasket_register_device with the module's gasket_driver_desc
struct. Finally, the driver must define an exit function that calls
gasket_unregister_device with the module's gasket_driver_desc struct.
One of the core assumptions of the Gasket framework is that precisely
one process is allowed to have an open write handle to the device node
at any given time. (That process may, once it has one write handle, open
any number of additional write handles.) This is accomplished by
tracking open and close data for each driver instance.

It's been four years since this was added. In the interim, skein has
not seen any mainstream adoption. Same with the threefish block cipher
upon which it's based.
In the discussion over which hash algorithm will replace SHA1 in git,
it's not one of the contenders.
There's absolutely no reason to think that there is anything wrong with
Skein or Threefish. The only reason for this removal is a lack of
adoption.
If a real user comes forward, I'd be happy to assist with integrating
this code into mainline.

The ipx code moved into the staging tree back in November 2017 and no
one has complained or even noticed it was gone. Because of that, let's
just delete it.
Note, the ipx header files are not removed here, that will come later
through the networking tree, as that takes a bit more work to unwind.

The Lustre filesystem has been in the kernel tree for over 5 years now.
While it has been an endless source of enjoyment for new kernel
developers learning how to do basic codingstyle cleanups, as well as an
semi-entertaining source of bewilderment from the vfs developers any
time they have looked into the codebase to try to figure out how to port
their latest api changes to this filesystem, it has not really moved
forward into the "this is in shape to get out of staging" despite many
half-completed attempts.
And getting code out of staging is the main goal of that portion of the
kernel tree. Code should not stagnate and it feels like having this
code in staging is only causing the development cycle of the filesystem
to take longer than it should. There is a whole separate out-of-tree
copy of this codebase where the developers work on it, and then random
changes are thrown over the wall at staging at some later point in time.
This dual-tree development model has never worked, and the state of this
codebase is proof of that.
So, let's just delete the whole mess. Now the lustre developers can go
off and work in their out-of-tree codebase and not have to worry about
providing valid changelog entries and breaking their patches up into
logical pieces. They can take the time they have spend doing those
types of housekeeping chores and get the codebase into a much better
shape, and it can be submitted for inclusion into the real part of the
kernel tree when ready.

NeilBrown:
Added range-check on pdev->id before assigning ot
host->id
of_dma_configure() sets a default ->dma_mask of
DMA_BIT_MASK(32), claiming devices can DMA from
the full 32bit address space.
The mtk-mmc driver does not support access to
highmem pages, so it is really limited to the
bottom 512M (actually 448M due to 64M of IO space).
Setting ->dma_mask to NULL causes mmc_setup_queue()
to fall-back to using BLK_BOUNCE_HIGH to tell the
block layer to use a bounce-buffer for any highmem
pages requiring IO.

No one has publicly stepped up to maintain this broken codebase for
devices that no one uses anymore, so let's just drop the whole thing.
If someone really wants/needs it, we can revert this and they can fix
the code up to work properly.

It's time to get rid of IRDA. It's long been broken, and no one seems
to use it anymore. So move it to staging and after a while, we can
delete it from there.
To start, move the network irda core from net/irda to
drivers/staging/irda/net/

The RTL8822BE, an 802.11ac wireless network card, is now appearing in
new computers. Its driver is being placed in staging to reduce the time
that users of this new card will have access to in-kernel drivers.
This commit enables building of the new driver. For this version, all
routines are built into a single module r8822be. When this driver is
moved to the wireless tree, halmac, phydm, and rtl8822be will become
new modules.

This commit adds the vboxvideo drm/kms driver for the virtual graphics
card used in Virtual Box virtual machines to drivers/staging.
Why drivers/staging? This driver is already being patched into the kernel
by several distros, thus it is good to get this driver upstream soon, so
that work on the driver can be easily shared.
At the same time we want to take our time to get this driver properly
cleaned up (mainly converted to the new atomic modesetting APIs) before
submitting it as a normal driver under drivers/gpu/drm, putting this
driver in staging for now allows both.
Note this driver has already been significantly cleaned up, when I started
working on this the files under /usr/src/vboxguest/vboxvideo as installed
by Virtual Box 5.1.18 Guest Additions had a total linecount of 52681
lines. The version in this commit has 4874 lines.
