We add device tree files for a couple of additional SoCs in various areas:
Allwinner R40/V40 for entertainment, Broadcom Hurricane 2 for networking,
Amlogic A113D for audio, and Renesas R-Car V3M for automotive.
As usual, lots of new boards get added based on those and other SoCs:
- Actions S500 based CubieBoard6 single-board computer
- Amlogic Meson-AXG A113D based development board
- Amlogic S912 based Khadas VIM2 single-board computer
- Amlogic S912 based Tronsmart Vega S96 set-top-box
- Allwinner H5 based NanoPi NEO Plus2 single-board computer
- Allwinner R40 based Banana Pi M2 Ultra and Berry single-board computers
- Allwinner A83T based TBS A711 Tablet
- Broadcom Hurricane 2 based Ubiquiti UniFi Switch 8
- Broadcom bcm47xx based Luxul XAP-1440/XAP-810/ABR-4500/XBR-4500
wireless access points and routers
- NXP i.MX51 based Zodiac Inflight Innovations RDU1 board
- NXP i.MX53 based GE Healthcare PPD biometric monitor
- NXP i.MX6 based Pistachio single-board computer
- NXP i.MX6 based Vining-2000 automotive diagnostic interface
- NXP i.MX6 based Ka-Ro TX6 Computer-on-Module in additional variants
- Qualcomm MSM8974 (Snapdragon 800) based Fairphone 2 phone
- Qualcomm MSM8974pro (Snapdragon 801) based Sony Xperia Z2 Tablet

- Renasas r8a7745 based iWave G22D-SODIMM SoM
- Rockchip rk3288 based Amarula Vyasa single-board computer
- Samsung Exynos5800 based Odroid HC1 single-board computer
For existing SoC support, there was a lot of ongoing work, as usual
most of that concentrated on the Renesas, Rockchip, OMAP, i.MX, Amlogic

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.

Power area A2VC0 was removed in revision ES2.0, cfr. R-Car Gen3 Hardware
User's Manual rev. 0.53E.
Hence remove it from the power area table when not running on ES1.x.
This is in line with the goal to:
1. Support both the ES1.x and ES2.0 SoC revisions in a single binary
for now,
2. Make it clear which code supports ES1.x, so it can easily be
identified and removed later, when production SoCs are deemed
ubiquitous.

Driver updates for ARM SoCs, including a couple of newly added drivers:
- A new driver for the power management controller on TI Keystone
- Support for the prerelease "SCPI" firmware protocol that ended up
being shipped by Amlogic in their GXBB SoC.
- A soc_device can now be matched using a glob from inside the
kernel, when another driver wants to know the specific chip
it is running on and cannot find out from DT, firmware or hardware.
- Renesas SoCs now support identification through the soc_device
interface, both in user space and kernel.
- Renesas r8a7743 and r8a7745 gain support for their system controller
- A new checking module for the ARM "PSCI" (not to be confused
with "SCPI" mentioned above) firmware interface.
- A new driver for the Tegra GMI memory interface
- Support for the Tegra firmware interfaces with their
power management controllers
As usual, the updates for the reset controller framework are merged
here, as they tend to touch multiple SoCs as well, including a new
driver for the Oxford (now Broadcom) OX820 chip and the Tegra
bpmp interface.
The existing drivers for Atmel, Qualcomm, NVIDIA, TI Davinci, and
Rockchips SoCs see some further updates.
Conflicts:
- ARCH_RENESAS now selects SOC_BUS, but no longer needs GPIOLIB
- drivers/soc/renesas/Makefile: multiple files got added, keep
all in logical sorting

Merge tag 'armsoc-drivers' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC driver updates from Arnd Bergmann:
"Driver updates for ARM SoCs, including a couple of newly added
drivers:
- A new driver for the power management controller on TI Keystone
- Support for the prerelease "SCPI" firmware protocol that ended up
being shipped by Amlogic in their GXBB SoC.
- A soc_device can now be matched using a glob from inside the
kernel, when another driver wants to know the specific chip it is
running on and cannot find out from DT, firmware or hardware.
- Renesas SoCs now support identification through the soc_device
interface, both in user space and kernel.
- Renesas r8a7743 and r8a7745 gain support for their system
controller
- A new checking module for the ARM "PSCI" (not to be confused with
"SCPI" mentioned above) firmware interface.
- A new driver for the Tegra GMI memory interface
- Support for the Tegra firmware interfaces with their power
management controllers
As usual, the updates for the reset controller framework are merged
here, as they tend to touch multiple SoCs as well, including a new
driver for the Oxford (now Broadcom) OX820 chip and the Tegra bpmp
interface.
The existing drivers for Atmel, Qualcomm, NVIDIA, TI Davinci, and
Rockchips SoCs see some further updates"

IVC is an inter-processor communication protocol that uses shared memory
to exchange data between processors. The BPMP driver makes use of this
to communicate with the Boot and Power Management Processor (BPMP) and
uses an additional hardware synchronization primitive from the HSP block
to signal availability of new data (doorbell).
Firmware running on the BPMP implements a number of services such as the
control of clocks and resets within the system, or the ability to ungate
or gate power partitions.

This adds a power domain driver for the Mediatek SCPSYS unit.
The System Control Processor System (SCPSYS) has several power
management related tasks in the system. The tasks include thermal
measurement, dynamic voltage frequency scaling (DVFS), interrupt
filter and lowlevel sleep control. The System Power Manager (SPM)
inside the SCPSYS is for the MTCMOS power domain control.
For now this driver only adds power domain support, the more
advanced features are not yet supported. The driver implements
the generic PM domain device tree bindings, the first user will
most likely be the Mediatek AFE audio driver.
