If the FUSE registers are accessed but the region is not mapped, warn
and return 0. This potentially catches hard to diagnose bugs because the
accesses happen before any kernel log output.

The tegra_read_chipid() function can be called from places other than
tegra_get_chip_id(), so the check for a valid mapping of the MISC
registers needs to be moved to tegra_read_chipid() to catch all
potential accesses.

Tegra210 and Tegra186 are mostly compatible from a fuses point of view.
However, speedo support is implemented in the BPMP firmware, hence the
implementation needs to be skipped in the fuses driver.

This branch contains platform-related driver updates for ARM and ARM64,
these are the areas that bring the changes:
New drivers:
- Driver support for Renesas R-Car V3M (R8A77970)
- Power management support for Amlogic GX
- A new driver for the Tegra BPMP thermal sensor
- A new bus driver for Technologic Systems NBUS
Changes for subsystems that prefer to merge through arm-soc:
- The usual updates for reset controller drivers from Philipp Zabel,
with five added drivers for SoCs in the arc, meson, socfpa, uniphier
and mediatek families.
- Updates to the ARM SCPI and PSCI frameworks, from Sudeep Holla,
Heiner Kallweit and Lorenzo Pieralisi.
Changes specific to some ARM-based SoC
- The Freescale/NXP DPAA QBMan drivers from PowerPC can now work
on ARM as well.
- Several changes for power management on Broadcom SoCs
- Various improvements on Qualcomm, Broadcom, Amlogic, Atmel, Mediatek
- Minor Cleanups for Samsung, TI OMAP SoCs

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

soc/tegra: bpmp: Check BPMP response return code
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.

The Qualcomm remote file system protocol is used by certain remoteprocs,
in particular the modem, to read and write persistent storage in
platforms where only the application CPU has physical storage access.
The protocol is based on a set of QMI-encoded control-messages and a
shared memory buffer for exchaning the data. This driver implements the
latter, providing the user space service access to the carved out chunk
of memory.

This requires quite a lot of code in order to deal with the
different HW blocks that need to be quiesced during suspend:
- DDR PHY
- DDR memory controller and arbiter
- control processor
The final steps of the suspend execute in cache and there is is a little
bit of assembly code in order to shut down the DDR PHY PLL and then go
into a wait loop until a wake-up even occurs. Conversely the resume part
involves waiting for the DDR PHY PLL to come back up and resume

This commit adds support for the Broadcom STB S2/S3/S5 suspend states on
ARM based SoCs.
This requires quite a lot of code in order to deal with the different HW
blocks that need to be quiesced during suspend:
- DDR PHY SHIM
- DDR memory controller and sequencer
- control processor
The final steps of the suspend execute in an on-chip SRAM and there is a
little bit of assembly code in order to shut down the DDR PHY PLL and
then go into a wfi loop until a wake-up even occurs. Conversely the
resume part involves waiting for the DDR PHY PLL to come back up and
resume executions where we left.
For S3, because of our memory hashing (actual hashing code not included
for simplicity, and is bypassed) we need to relocate the writable
variables (stack) into SRAM shortly before suspending in order to leave
the DRAM untouched and create a reliable hash of its contents.
This code has been contributed by Brian Norris initially and has been
incrementally fixed and updated to support new chips by a lot of people.
