large change that introduces runtime PM support to the clk framework. Now we
properly call runtime PM operations on the device providing a clk when the clk
is in use. This helps on SoCs where the clks provided by a device need
something to be powered on before using the clks, like power domains or
regulators. It also helps power those things down when clks aren't in use. The
other core change is a devm API addition for clk providers so we can get rid of
a bunch of clk driver remove functions that are just doing
of_clk_del_provider().
Outside of the core, we have the usual addition of clk drivers and smattering
of non-critical fixes to existing drivers. The biggest diff is support for
Mediatek MT2712 and MT7622 SoCs, but those patches really just add a bunch
of data.
By the way, we're trying something new here where we build the tree up with
topic branches. We plan to work this into our workflow so that we don't step
on each other's toes, and so the fixes branch can be merged on an as-needed
basis.

- Runtime PM support for clk providers
- devm API for of_clk_add_hw_provider()

- Mediatek MT2712 and MT7622

because the R8A77970 driver is missing a header file that came from

Allwinner R40/V40 for entertainment, Broadcom Hurricane 2 for networking,
Amlogic A113D for audio, and Renesas R-Car V3M for automotive.

Rob Herring and many others worked on reducing the number of issues that
the latest version of 'dtc' now warns about. Unfortunately there is still
a lot left to do.

kernel cycle:
Core:
- The pin control Kconfig entry PINCTRL is now turned into
a menuconfig option. This obviously has the implication of
making the subsystem menu visible in menuconfig. This is
happening because of two things:
- Intel have started to deploy and depend on pin controllers
in a way that is affecting users directly. This happens
on the highly integrated laptop chipsets named after
geographical places: baytrail, broxton, cannonlake,
cedarfork, cherryview, denverton, geminilake, lewisburg,
merrifield, sunrisepoint... It started a while back and
now it is ever more evident that this is crucial
infrastructure for x86 laptops and not an embedded
obscurity anymore. Users need to be aware.
- Pin control expanders on I2C and SPI that are
arch-agnostic. Currently Semtech SX150X and Microchip
MCP28x08 but more are expected. Users will have to be
able to configure these in directly for their set-up.
- Just go and select GPIOLIB now that we made sure that
GPIOLIB is a very vanilla subsystem. Do not depend on
it, if we need it, select it.
- Exposing the pin control subsystem in menuconfig uncovered
a bunch of obscure bugs that are now hopefully fixed,
all more or less pertaining to Blackfin.
- Unified namespace for cross-calls between pin control and
GPIO.
- New support for clock skew/delay generic DT bindings
and generic pin config options for this.
- Minor documentation improvements.
Various:
- The Renesas SH-PFC pin controller has evolved a lot. It seems
Renesas are churning out new SoCs by the minute.
- A bunch of non-critical fixes for the Rockchip driver.
- Improve the use of library functions instead of open coding.

CORE:
- Fix the semantics of raw GPIO to actually be raw. No
inversion semantics as before, but also no open draining,
and allow the raw operations to affect lines used for
interrupts as the caller supposedly knows what they are
doing if they are getting the big hammer.
- Rewrote the __inner_function() notation calls to names that
make more sense. I just find this kind of code disturbing.
- Drop the .irq_base() field from the gpiochip since now all
IRQs are mapped dynamically. This is nice.
- Support for .get_multiple() in the core driver API. This
allows us to read several GPIO lines with a single
register read. This has high value for some usecases: it
can be used to create oscilloscopes and signal analyzers
and other things that rely on reading several lines at
exactly the same instant. Also a generally nice
optimization. This uses the new assign_bit() macro from
the bitops lib that was ACKed by Andrew Morton and
is implemented for two drivers, one of them being the
generic MMIO driver so everyone using that will be able
to benefit from this.
- Do not allow requests of Open Drain and Open Source
setting of a GPIO line simultaneously. If the hardware
actually supports enabling both at the same time the
electrical result would be disastrous.
- A new interrupt chip core helper. This will be helpful
to deal with "banked" GPIOs, which means GPIO controllers
with several logical blocks of GPIO inside them. This
is several gpiochips per device in the device model, in
contrast to the case when there is a 1-to-1 relationship
between a device and a gpiochip.
NEW DRIVERS:
- Maxim MAX3191x industrial serializer, a very interesting
piece of professional I/O hardware.
- Uniphier GPIO driver. This is the GPIO block from the
recent Socionext (ex Fujitsu and Panasonic) platform.
- Tegra 186 driver. This is based on the new banked GPIO
infrastructure.

- Some documentation improvements.
- Wakeup support for the DesignWare DWAPB GPIO controller.
- Reset line support on the DesignWare DWAPB GPIO controller.
- Several non-critical bug fixes and improvements for the
Broadcom BRCMSTB driver.

of dead code etc.

Here is the big set of USB and PHY driver updates for 4.15-rc1.
There is the usual amount of gadget and xhci driver updates, along with
phy and chipidea enhancements. There's also a lot of SPDX tags and
license boilerplate cleanups as well, which provide some churn in the
diffstat.
Other major thing is the typec code that moved out of staging and into
the "real" part of the drivers/usb/ tree, which was nice to see happen.
All of these have been in linux-next with no reported issues for a

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.

Add the infrastructure to support the idea of multiple ringbuffers.
Assign each ringbuffer an id and use that as an index for the various
ring specific operations.
The biggest delta is to support legacy fences. Each fence gets its own
sequence number but the legacy functions expect to use a unique integer.
To handle this we return a unique identifier for each submission but
map it to a specific ring/sequence under the covers. Newer users use
a dma_fence pointer anyway so they don't care about the actual sequence
ID or ring.
The actual mechanics for multiple ringbuffers are very target specific
so this code just allows for the possibility but still only defines
one ringbuffer for each target family.

This GPIO controller is used on UniPhier SoC family.
The vendor specific property "socionext,interrupt-ranges" is for
specifying interrupt mapping to the parent interrupt controller
because the mapping is not contiguous. It works like "ranges",
but transforms "interrupts" instead of "reg".

Literally.
I expect "lose" was meant here, rather than "loose", though you could feasibly
use a somewhat uncommon definition of "loose" to mean what would be meant by
"lose": "Loose the hounds" for instance, as in "Release the hounds".
Substituting in "value" for "hounds" gives "release the value", and makes some
sense, but futher substituting back to loose gives "loose the value" which
overall just seems a bit anachronistic.
Instead, use modern, pragmatic English and save a character.

The sor1_src clock implemented on Tegra210 is modelled the wrong way
around, which causes some issues with HDMI and DP support. This clock
implementation is provided by BPMP on Tegra186, which models this in
a more correct way. Since this introduces incompatibilities between
the two SoC generations which we want to avoid, the Tegra210 will be
fixed in subsequent patches.
This change adds sor1_out as an alias for sor1_src.

Initially each pin was declared in "include/dt-bindings/stm32<SOC>-pinfunc.h"
and each definition contained SOC names (ex: STM32F429_PA9_FUNC_USART1_TX).
Since this approach was approved, the number of supported MCU has
increased (STM32F429/STM32F469/STM32f746/STM32H743). To avoid to add a new
file in "include/dt-bindings" each time a new STM32 SOC arrives I propose
a new approach which consist to use a macro to define pin muxing in device
tree. All STM32 will use the common macro to define pinmux. Furthermore, it
will make STM32 maintenance and integration of new SOC easier .
