The pm-rmobile driver is really a driver for the System Controller
(SYSC) found in R-Mobile SoCs. An equivalent driver for R-Car SoCs is
already located under drivers/soc/renesas/.
Hence move the pm-rmobile driver from arch/arm/mach-shmobile/ to
drivers/soc/renesas/, and rename it to rmobile-sysc.
Enable compile-testing on non-ARM and non-R-Mobile SoCs.

As of commit cad160ed0a94927e ("ARM: shmobile: Convert file to use
cntvoff"), there's no non-SMP code left in headsmp-apmu.S.
Hence build the file for SMP only, and drop the no longer needed check
for CONFIG_SMP inside the file.

If the R-Car H1 system controller is described in DT, the rcar-sysc
driver configures SYSCIER and SYSCIMR based on the SoC-specific power
area definitions in r8a7779-sysc. The platform code still passed this
information to the rcar-sysc driver, for compatibility with old DTBs
predating commit b2df3aa487395a1b ("ARM: dts: r8a7779: Add SYSC PM
Domains") in v4.7. The time has come to drop backwards compatibility,
and delegate everything to the DT enabled rcar-sysc driver.
After stopping powering down secondary CPUs during early boot, there is
no longer a need to force an early initialization of the rcar-sysc
driver. It will be initialized in time for secondary CPU bringup by its
early_initcall().
Hence all explicit SYSC configuration and initialization can be removed
from the R-Car H1 platform code.

Pull ARM SoC platform updates from Arnd Bergmann:
"Most of the commits are for defconfig changes, to enable newly added
drivers or features that people have started using. For the changed
lines lines, we have mostly cleanups, the affected platforms are OMAP,
Versatile, EP93xx, Samsung, Broadcom, i.MX, and Actions.
The largest single change is the introduction of the TI "sysc" bus
driver, with the intention of cleaning up more legacy code.
Two new SoC platforms get added this time:
- Allwinner R40 is a modernized version of the A20 chip, now with a
Quad-Core ARM Cortex-A7. According to the manufacturer, it is
intended for "Smart Hardware"
- Broadcom Hurricane 2 (Aka Strataconnect BCM5334X) is a family of
chips meant for managed gigabit ethernet switches, based around a
Cortex-A9 CPU.
Finally, we gain SMP support for two platforms: Renesas R-Car E2 and
Amlogic Meson8/8b, which were previously added but only supported
uniprocessor operation"

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.

On Cortex-A7, the arch timer CNTVOFF register is uninitialized.
Ideally it should be initialized by the boot loader, but it isn't.
For the boot CPU, CNTVOFF is initialized by Linux since commit
9ce3fa6816c2fb59 ("ARM: shmobile: rcar-gen2: Add CA7 arch_timer
initialization for r8a7794").
For secondary CPU cores, no such initialization is done.
Hence when enabling SMP on r8a7794, the kernel log is spammed with:
WARNING: Underflow in clocksource 'arch_sys_counter' observed, time update ignored.
Please report this, consider using a different clocksource, if possible.
Your kernel is probably still fine.
As Marc Zyngier pointed out that Cortex-A15 and Cortex-A7 are similar with
respect to CNTVOFF, we have been very lucky this just worked on R-Car
Gen2 SoCs with Cortex-A15 cores.
To fix this:
- Move the existing inline asm code to initialize CNTVOFF to an
assembler source file (adding comments and replacing hardcoded
constants by definitions in the process), so it can be reused,
- Perform the initialization of CNTVOFF on the boot CPU (Cortex-A15 or
Cortex-A7) on all R-Car Gen2 and RZ/G1 parts,
- Wrap the standard secondary_startup() routine inside a routine which
initializes CNTVOFF.
Based on patches by Hisashi Nakamura in the BSP.

Move the pm-rcar driver from arch/arm/mach-shmobile/ to
drivers/soc/renesas/, and its header file to include/linux/soc/renesas/,
so it can be shared between arm32 (R-Car H1 and Gen2) and arm64 (R-Car

System Controller (SYSC).
Kill the intermediate PM_RCAR config symbol, as it's not user

Pull ARM SoC platform updates from Olof Johansson:
"Our SoC branch usually contains expanded support for new SoCs and
other core platform code. In this case, that includes:
- support for the new Annapurna Labs "Alpine" platform
- a rework greatly simplifying adding new platform support to the
MCPM subsystem (Multi-cluster power management)
- cpuidle and PM improvements for Exynos3250
- misc updates for Renesas, OMAP, Meson, i.MX. Some of these could
have gone in other branches but ended up here for various reasons"

The default idle driver uses one state with the WFI instruction.
The default idle routine invokes WFI when no cpuidle driver is present.
The default cpuidle driver is pointless and does not give more than the
default idle routine and moreover it pulls all the mathematics tied with
the cpuidle governor for nothing, hence consuming more energy.
Remove the default driver, the related code and register the driver directly.

The r8a7790/lager and r8a7791/koelsch development boards have da9063 and
da9210 regulators. Both regulators have their interrupt request lines
tied to the same interrupt pin (IRQ2) on the SoC.
After cold boot or da9063-induced restart, both the da9063 and da9210
seem to assert their interrupt request lines. Hence as soon as one
driver requests this irq, it gets stuck in an interrupt storm, as it
only manages to deassert its own interrupt request line, and the other
driver hasn't installed an interrupt handler yet.
To handle this, install a quirk that masks the interrupts in both the
da9063 and da9210. This quirk has to run after the i2c master driver
has been initialized, but before the i2c slave drivers are initialized.
As it depends on i2c, select I2C if one of the affected platforms is
enabled in the kernel config.
On koelsch, the following happens:
- Cold boot or reboot using the da9063 restart handler:
IRQ2 is asserted, installing da9063/da9210 regulator quirk
...
i2c i2c-6: regulator_quirk_notify: 1, IRQC_MONITOR = 0x3fb
i2c 6-0058: regulator_quirk_notify: 1, IRQC_MONITOR = 0x3fb
i2c 6-0058: Detected da9063
i2c 6-0058: Masking da9063 interrupt sources
i2c 6-0068: regulator_quirk_notify: 1, IRQC_MONITOR = 0x3fb
i2c 6-0068: Detected da9210
i2c 6-0068: Masking da9210 interrupt sources
i2c 6-0068: IRQ2 is not asserted, removing quirk
- Warm boot (reset button):
rcar_gen2_regulator_quirk: IRQ2 is not asserted, not installing quirk

Remove support for the legacy Cortex-A8 based sh7372 SoC.
The Linux kernel still lacks DT bindings for the sh7372 INTC
interrupt controller so DT multiplatform support is not possibile.
Also, the sh7372 SoC never went into mass production anyway so to
aid migration to DT multiplatform simply get rid of sh7372 support.
