f9a82c4820 staging: add Fieldbus Device subsystem.
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.

441bf7332d staging: m57621-mmc: delete driver from the tree.
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.

b1bd42aa72 staging: xgifb: delete the driver
There has not been any real work done on cleaning this driver up and
getting it out of the staging tree in years.  Also, no new fb drivers
are being added to the tree, so it should be converted into a drm driver
as well.

Due to the lack of interest in this codebase, just drop it.

9a41352614 staging: Mediatek: Use individual config flags in Makefile
These drivers can be useful on other MT76xx SoCs, which have compatible
peripherals.  The drivers were selectable in Kconfig, but they were
quietly excluded from the build because the SOC_MT7621 chip was not
selected.  So, make the Makefiles use the same flags as Kconfig for
these drivers.

mt7621-dma and mt7621-dts are left alone because they truly do require
that SoC.

I have personally confirmed that the mt7621-spi driver works on the
MT7688, which was what prompted this change.

This is in preparation to allow it and the mt7621-dma drivers to be

and the Kconfig specifies very different requirements.

2475c515d4 Staging/IIO patches for 4.19-rc1
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
 reported issues.
 
 Note, you will have a merge problem with a device tree IIO file and the
 MAINTAINERS file, both resolutions are easy, just take all changed.
 There will be a skein file merge issue as well, but that file got
 deleted so just drop that.

4a965c5f89 staging: add driver for Xilinx AXI-Stream FIFO v4.1 IP core
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.

https://www.xilinx.com/support/documentation/ip_documentation/axi_fifo_mm_s/v4_1/pg080-axi-fifo-mm-s.pdf

The driver currently supports only store-forward mode with a 32-bit
AXI4 Lite interface. DOES NOT support:
        - cut-through mode
        - AXI4 (non-lite)

9a69f5087c drivers/staging: Gasket driver framework + Apex driver
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.

ee55fe552f staging/skein: Remove Skein and Threefish code
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.

be65f9ed26 staging: lustre: delete the filesystem from the tree.
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

  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.

d64c2a7612 staging: irda: remove the irda network stack and drivers
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.

b24413180f License cleanup: add SPDX GPL-2.0 license identifier to files with no license
Many source files in the tree are missing licensing information, which
makes it harder for compliance tools to determine the correct license.

By default all files without license information are under the default
license of the kernel, which is GPL version 2.

Update the files which contain no license information with the 'GPL-2.0'
SPDX license identifier.  The SPDX identifier is a legally binding
shorthand, which can be used instead of the full boiler plate text.

This patch is based on work done by Thomas Gleixner and Kate Stewart and
Philippe Ombredanne.

How this work was done:

Patches were generated and checked against linux-4.14-rc6 for a subset of
the use cases:
 - file had no licensing information it it.
 - file was a */uapi/* one with no licensing information in it,
 - file was a */uapi/* one with existing licensing information,

Further patches will be generated in subsequent months to fix up cases
where non-standard license headers were used, and references to license
had to be inferred by heuristics based on keywords.

The analysis to determine which SPDX License Identifier to be applied to
a file was done in a spreadsheet of side by side results from of the
output of two independent scanners (ScanCode & Windriver) producing SPDX
tag:value files created by Philippe Ombredanne.  Philippe prepared the
base worksheet, and did an initial spot review of a few 1000 files.

The 4.13 kernel was the starting point of the analysis with 60,537 files
assessed.  Kate Stewart did a file by file comparison of the scanner
results in the spreadsheet to determine which SPDX license identifier(s)
to be applied to the file. She confirmed any determination that was not
immediately clear with lawyers working with the Linux Foundation.

Criteria used to select files for SPDX license identifier tagging was:
 - Files considered eligible had to be source code files.
 - Make and config files were included as candidates if they contained >5
   lines of source
 - File already had some variant of a license header in it (even if <5
   lines).

All documentation files were explicitly excluded.

The following heuristics were used to determine which SPDX license
identifiers to apply.

 - when both scanners couldn't find any license traces, file was
   considered to have no license information in it, and the top level
   COPYING file license applied.

   For non */uapi/* files that summary was:

   SPDX license identifier                            # files
   ---------------------------------------------------|-------
   GPL-2.0                                              11139

   and resulted in the first patch in this series.

   If that file was a */uapi/* path one, it was "GPL-2.0 WITH
   Linux-syscall-note" otherwise it was "GPL-2.0".  Results of that was:

   SPDX license identifier                            # files
   ---------------------------------------------------|-------
   GPL-2.0 WITH Linux-syscall-note                        930

   and resulted in the second patch in this series.

 - if a file had some form of licensing information in it, and was one
   of the */uapi/* ones, it was denoted with the Linux-syscall-note if
   any GPL family license was found in the file or had no licensing in
   it (per prior point).  Results summary:

   SPDX license identifier                            # files
   ---------------------------------------------------|------
   GPL-2.0 WITH Linux-syscall-note                       270
   GPL-2.0+ WITH Linux-syscall-note                      169
   ((GPL-2.0 WITH Linux-syscall-note) OR BSD-2-Clause)    21
   ((GPL-2.0 WITH Linux-syscall-note) OR BSD-3-Clause)    17
   LGPL-2.1+ WITH Linux-syscall-note                      15
   GPL-1.0+ WITH Linux-syscall-note                       14
   ((GPL-2.0+ WITH Linux-syscall-note) OR BSD-3-Clause)    5
   LGPL-2.0+ WITH Linux-syscall-note                       4
   LGPL-2.1 WITH Linux-syscall-note                        3
   ((GPL-2.0 WITH Linux-syscall-note) OR MIT)              3
   ((GPL-2.0 WITH Linux-syscall-note) AND MIT)             1

   and that resulted in the third patch in this series.

 - when the two scanners agreed on the detected license(s), that became
   the concluded license(s).

 - when there was disagreement between the two scanners (one detected a
   license but the other didn't, or they both detected different
   licenses) a manual inspection of the file occurred.

 - In most cases a manual inspection of the information in the file
   resulted in a clear resolution of the license that should apply (and
   which scanner probably needed to revisit its heuristics).

 - When it was not immediately clear, the license identifier was
   confirmed with lawyers working with the Linux Foundation.

 - If there was any question as to the appropriate license identifier,
   the file was flagged for further research and to be revisited later
   in time.

In total, over 70 hours of logged manual review was done on the
spreadsheet to determine the SPDX license identifiers to apply to the
source files by Kate, Philippe, Thomas and, in some cases, confirmation
by lawyers working with the Linux Foundation.

Kate also obtained a third independent scan of the 4.13 code base from
FOSSology, and compared selected files where the other two scanners
disagreed against that SPDX file, to see if there was new insights.  The
Windriver scanner is based on an older version of FOSSology in part, so
they are related.

Thomas did random spot checks in about 500 files from the spreadsheets
for the uapi headers and agreed with SPDX license identifier in the
files he inspected. For the non-uapi files Thomas did random spot checks
in about 15000 files.

In initial set of patches against 4.14-rc6, 3 files were found to have
copy/paste license identifier errors, and have been fixed to reflect the
correct identifier.

Additionally Philippe spent 10 hours this week doing a detailed manual
inspection and review of the 12,461 patched files from the initial patch
version early this week with:
 - a full scancode scan run, collecting the matched texts, detected
   license ids and scores
 - reviewing anything where there was a license detected (about 500+
   files) to ensure that the applied SPDX license was correct
 - reviewing anything where there was no detection but the patch license
   was not GPL-2.0 WITH Linux-syscall-note to ensure that the applied
   SPDX license was correct

This produced a worksheet with 20 files needing minor correction.  This
worksheet was then exported into 3 different .csv files for the
different types of files to be modified.

These .csv files were then reviewed by Greg.  Thomas wrote a script to
parse the csv files and add the proper SPDX tag to the file, in the
format that the file expected.  This script was further refined by Greg
based on the output to detect more types of files automatically and to
distinguish between header and source .c files (which need different
comment types.)  Finally Greg ran the script using the .csv files to
generate the patches.

dd55d44f40 staging: vboxvideo: Add vboxvideo to drivers/staging
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.

	usb: typec: add driver for Intel Whiskey Cove PMIC USB Type-C PHY
	usb: USB Type-C connector class

This driver only implements the state machine. Lower level drivers are
responsible for
- Reporting VBUS status and activating VBUS
- Setting CC lines and providing CC line status
- Setting line polarity
- Activating and deactivating VCONN
- Setting the current limit
- Activating and deactivating PD message transfers
- Sending and receiving PD messages

The driver provides both a functional API as well as callbacks for
lower level drivers.
