Linus Torvalds b630a23a73 This is the bulk of pin control changes for the v4.15
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.
 
 - Support the MCP28018 variant in the MCP28x08 driver.

Greg Kroah-Hartman 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.

Geert Uytterhoeven 8843797df3 pinctrl: sh-pfc: Save/restore registers for PSCI system suspend
During PSCI system suspend, R-Car Gen3 SoCs are powered down, and their
pinctrl register state is lost.  Note that as the boot loader skips most
initialization after system resume, pinctrl register state differs from
the state encountered during normal system boot, too.

To fix this, save all GPIO and peripheral function select, module
select, drive strength control, bias, and other I/O control registers
during system suspend, and restore them during system resume.

Note that to avoid overhead on platforms not needing it, the
suspend/resume code has a build time dependency on sleep and PSCI
support, and a runtime dependency on PSCI.

Inspired by a patch in the BSP by Hien Dang.

Takeshi Kihara b014912f6c pinctrl: sh-pfc: r8a7796: Add support for INTC-EX IRQ pins
Most pins on the r8a7796 SoC can be configured in GPIO mode for
interrupt and GPIO functionality, while a couple of them can also
be routed to the INTC-EX hardware block (formerly known as IRQC).

On r8a7795 the INTC-EX hardware handles pins IRQ0 -> IRQ5 and
this patch adds support for them to the PFC driver as "intc_ex_irqN".

 r8a7795: Add support for INTC-EX IRQ pins")

Since pinmuxing for I2C is equal on H3 ES1.0 and later versions, copy
the I2C settings from ES1.0. Fixes this error in upstream for
Salvator-XS:

sh-pfc e6060000.pin-controller: function 'i2c2' not supported
sh-pfc e6060000.pin-controller: invalid function i2c2 in map table

The pinctrl_request_gpio() and pinctrl_free_gpio() break the nice
namespacing in the other cross-calls like pinctrl_gpio_foo().
Just rename them and all references so we have one namespace
with all cross-calls under pinctrl_gpio_*().
