Here is the "big" staging and IIO driver update for 4.15-rc1.
Lots and lots of little changes, almost all minor code cleanups as the
Outreachy application process happened during this development cycle.
Also happened was a lot of IIO driver activity, and the typec USB code
moving out of staging to drivers/usb (same commits are in the USB tree
on a persistent branch to not cause merge issues.)
Overall, it's a wash, I think we added a few hundred more lines than
removed, but really only a few thousand were modified at all.
All of these have been in linux-next for a while. There might be a
merge issue with Al's vfs tree in the pi433 driver (take his changes,
they are always better), and the media tree with some of the odd atomisp
cleanups (take the media tree's version).

Loopback has its own internal method for tracking and timing out
asynchronous operations however previous patches make it possible to use
functionality provided by operation.c to do this instead. Using the code in
operation.c means we can completely subtract the timer, the work-queue, the
kref and the cringe-worthy 'pending' flag. The completion callback
triggered by operation.c will provide an authoritative result code -
including -ETIMEDOUT for asynchronous operations.

Commit d9fb3754ec ("greybus: loopback: Relax locking during loopback

encapsulated by a per-driver level gb_dev.mutex.
Commit 8e1d6c336d ("greybus: loopback: drop bus aggregate calculation")
on the other hand subtracts the driver level gb_dev.mutex but neglects to
move the mutex back to the place it was prior to commit d9fb3754ec
("greybus: loopback: Relax locking during loopback operations"), as a
result several members of the per connection struct gb_loopback are racy.

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.

Pull media updates from Mauro Carvalho Chehab:
"Brazil's Independence Day pull request :-)
This is one of the biggest media pull requests, with 625 patches
affecting almost all parts of media (RC, DVB, V4L2, CEC, docs).
This contains:
- A lot of new drivers:
* DVB frontends: mxl5xx, stv0910, stv6111;
* camera flash: as3645a led driver;
* HDMI receiver: adv748X;
* camera sensor: Omnivision 6650 5M driver (ov6650);
* HDMI CEC: ao-cec meson driver;
* V4L2: Qualcom camss driver;
* Remote controller: gpio-ir-tx, pwm-ir-tx and zx-irdec drivers.
- The DDbridge DVB driver got a massive update, with makes it in sync
with modern hardware from that vendor;
- There's an important milestone on this series: the DVB
documentation was written in 2003, but only started to be updated
in 2007. It also used to contain several gaps from the time it was
kept out of tree, mentioning error codes and device nodes that
never existed upstream. On this series, it received a massive
update: all non-deprecated digital TV APIs are now in sync with the
current implementation;
- Some DVB APIs that aren't used by any upstream driver got removed;
- Other parts of the media documentation algo got updated, fixing
some bugs on its PDF output and making it compatible with Sphinx
version 1.6.
As the number of hacks required to build PDF output reduced, I hope
we'll have less troubles as newer versions of our documentation
toolchain are released (famous last words);
- As usual, lots of driver cleanups and improvements"

The V4L2 flash interface allows controlling multiple LEDs through a single
sub-devices if, and only if, these LEDs are of different types. This
approach scales badly for flash controllers that drive multiple flash LEDs
or for LED specific associations. Essentially, the original assumption of a
LED driver chip that drives a single flash LED and an indicator LED is no
longer valid.
Address the matter by registering one sub-device per LED.

Unnecessary platform_set_drvdata() has been removed since the driver
core clears the driver data to NULL after device release or on
probe failure. There is no need to manually clear the device
driver data to NULL.

Core changes:
- Switch the generic pin config argument from 16 to 24 bits,
only use 8 bits for the configuration type. We might need to
encode more information about a certain setting than we need
to encode different generic settings.
- Add a cross-talk API to the pin control GPIO back-end,
utilizing pinctrl_gpio_set_config() from GPIO drivers that
want to set up a certain pin configuration in the back-end.
This also includes the .set_config() refactoring of the
GPIO chips, so that they pass a generic configuration for
things like debouncing and single ended (typically open
drain). This change has also been merged in an immutable
branch to the GPIO tree.
- Take hogs with a delayed work, so that we finalize probing
a pin controller before trying to get any hogs.
- For pin controllers putting all group and function definitions
into the device tree, we now have generic code to deal with
this and it is used in two drivers so far.
- Simplifications of the pin request conflict check.
- Make dt_free_map() optional.
Updates to drivers:
- pinctrl-single now use the generic helpers to generate dynamic
group and function tables from the device tree.
- Texas Instruments IOdelay configuration driver add-on to
pinctrl-single.
- i.MX: use radix trees to store groups and functions, use the new
generic group and function helpers to manage them.
- Intel: add support for hardware debouncing and 1K pull-down.
New subdriver for the Gemini Lake SoC.
- Renesas SH-PFC: drive strength and bias support, CAN bus muxing,
MSIOF, SDHI, HSCIF for r8a7796. Gyro-ADC supporton r8a7791.
- Aspeed: use syscon cross-dependencies to set up related bits in
the LPC host controller and display controller.
- Aspeed: finalize G4 and G5 support. Fix mux configuration on
GPIOs. Add banks Y, Z, AA, AB and AC.
- AMD: support additional GPIO.

variants with the new variant framework.
- Mvebu: simplifications to use a MMIO and regmap abstraction.
New subdrivers for the 98DX3236, 98DX5241 SoCs.
- Samsung Exynos: delete Exynos4415 support. Add crosstalk to the

The loopback driver allows the user to set a minimum delay of up to one
second to be inserted between test iterations (i.e. request
submissions). The delay is currently specified in microseconds and is
implemented using udelay.
Busy looping for long periods is not just anti-social; udelay must not
be used for delays longer than a few milliseconds due to the risk of
integer overflow.
Replace the broken udelay with a usleep_range with a 100 us range for
short delays (< 20 ms) and otherwise revert to using msleep.

Currently we already have two pin configuration related callbacks
available for GPIO chips .set_single_ended() and .set_debounce(). In
future we expect to have even more, which does not scale well if we need
to add yet another callback to the GPIO chip structure for each possible
configuration parameter.
Better solution is to reuse what we already have available in the
generic pinconf.
To support this, we introduce a new .set_config() callback for GPIO
chips. The callback takes a single packed pin configuration value as
parameter. This can then be extended easily beyond what is currently
supported by just adding new types to the generic pinconf enum.
If the GPIO driver is backed up by a pinctrl driver the GPIO driver can
just assign gpiochip_generic_config() (introduced in this patch) to
.set_config and that will take care configuration requests are directed
to the pinctrl driver.
We then convert the existing drivers over .set_config() and finally
remove the .set_single_ended() and .set_debounce() callbacks.

Dummy codec register were initially added while populating dummy codec
mixer controls until module topology parser was available. Now, these
dummy registers are nowhere used and thus can be safely removed.
Since ASoC framework requires a valid callback for both read & write
register APIS, currently empty placeholders are kept to avoid panic.
Later, register mapping logic can be defined:
1. Assuming fixed number of maximum modules connected and register bits
corresponds to basic info of each module OR
2. With a logic to dynamically grow register_cache_size based on codec

Declare the 'arche_apb_ctrl_of_match' array as const. This array is only stored
in the .of_match_table field of a device_driver structure, which is declared as
const. This addresses the checkpatch warning:

Declare the arrays 'arche_platform_of_match' and 'arche_combined_id' as const.
'arche_platform_of_match' is only stored in the .of_match_table field of a
device_driver structure, which is declared as const.
'arche_combined_id' is passed to MODULE_DEVICE_TABLE. This macro does not
modify the array and therefore the array can be declared as const. Checkpatch
pointed out both issues.

The last thing remaining in kernel_ver.h was the setting of
CONFIG_PM_RUNTIME, which isn't needed in a in-tree implementation. So
remove the setting of this value, and the .h file entirely as that was
the last thing left in it.
