rcar_sysc_matches[] is used only by rcar_sysc_pd_init(), which is
__init. Hence mark rcar_sysc_matches[] __initconst.
This frees another 1764 bytes (arm32/shmobile_defconfig) or 1000 bytes
(arm64/renesas_defconfig) of memory after kernel init.

We were making a bunch of wrong assumptions that turned out to blow out
on non-Broadcom STB platforms:
- we would return -ENODEV from brcmstb_soc_device_early_init() if we
could not find the sun_top_ctrl device node, this is not an error
in the context of a multi-platform kernel
- we would still try to register the Broadcom STB SoC device, even if we
are not running on such a platform
While at it, also fix the sun_top_ctrl device_node leaks while we change
the flow of brcmstb_soc_device_init() and
brcmstb_soc_device_early_init().

Signed-off-by: Olof Johansson <olof@lixom.net>
After moving the SoC device initialization to an early initcall in
commit f780429adf ("soc: brcmstb: biuctrl: Move to early_initcall"),
the Broadcom STB SoC device is registered on all platforms if support
for the device is enabled in the kernel configuration.
This causes an additional SoC device to appear on platforms that already
register a native one. In case of Tegra the STB SoC device is registered
as soc0 (with totally meaningless content in the sysfs attributes) and
causes various scripts and programs to fail because they don't know how
to parse that data.
To fix this, duplicate the check from brcmstb_soc_device_early_init()
that already prevents the code from doing anything nonsensical on non-
STB platforms.

Geert Uytterhoeven says "If an R-Car SYSC slave device is part of the
CPG/MSTP or CPG/MSSR Clock Domain and to be used as a wakeup source, it
must be kept active during system suspend.
Currently this is handled in device-specific drivers by explicitly
increasing the use count of the module clock when the device is
configured as a wakeup source. However, the proper way to prevent the
device from being stopped is to inform this requirement to the genpd
core, by setting the GENPD_FLAG_ACTIVE_WAKEUP flag.
Note that this will only affect devices configured as wakeup sources."

Fix child-node lookup during probe, which ended up searching the whole

Note that the original premature free of the parent node has already
been fixed separately.
Also note that this pattern of looking up the first child node with a

warranted.

If an R-Car SYSC slave device is part of the CPG/MSTP or CPG/MSSR Clock
Domain and to be used as a wakeup source, it must be kept active during
system suspend.
Currently this is handled in device-specific drivers by explicitly
increasing the use count of the module clock when the device is
configured as a wakeup source. However, the proper way to prevent the
device from being stopped is to inform this requirement to the genpd
core, by setting the GENPD_FLAG_ACTIVE_WAKEUP flag.
Note that this will only affect devices configured as wakeup sources.

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.

pwrap initialization is highly associated with the base SoC and the
target PMICs, so slight refactorization is made here for allowing
pwrap_init to run on those PMICs with different capability from the
previous MediaTek PMICs and the determination for the enablement of the
pwrap capability depending on PMIC type. Apart from this, the patch
makes the driver more extensible especially when more PMICs join into
the pwrap driver.

This commit adds support for the Broadcom STB S2/S3/S5 suspend
states on MIPS 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
- 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
executions where we left.

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.

Compared to the old xrx200_phy_fw driver the new version has multiple
enhancements. The name of the firmware files does not have to be added
to all .dts files anymore - one now configures the GPHY mode (FE or GE)
instead. Each GPHY can now also boot separate firmware (thus mixing of
GE and FE GPHYs is now possible).
The new implementation is based on the RCU syscon-mfd and uses the
reeset_controller framework instead of raw RCU register reads/writes.

is attempted.
Give the genpd a name before registering it to avoid this.

Allwinner A64's display engine claims the SRAM C section to work.
Add support for the A64 SRAM controller and the SRAM C section of it.
Signed-off-by: Icenowy Zheng <icenowy@aosc.io>
Signed-off-by: Chen-Yu Tsai <wens@csie.org>
On some Allwinner SoCs, sometimes the value needed to write into the
register to claim SRAM is not equal to the value specified in the
device tree.
The device tree binding defines 0 as "mapped to CPU" and 1 as "mapped
to X device". This matches the value written to the configuration
register for the SRAM blocks currently supported. However, the not yet
supported VE SRAM block is claimed for the device by writing 0x7fffffff,
which is vastly different from the other blocks. On the A64, SRAM C is
claimed by the device by writing a 0, which is the opposite of the
current design.
Add a value remapping in sunxi_sram_func structure, and let the
sunxi_sram_of_parse function set the remapped register value.

When claiming SRAM, if the base is set to an error, it means that the
SRAM controller has been probed, but failed to remap the controller
memory zone. If the base is zero, thus the SRAM controller should be not
probed at all, and it should return -EPROBE_DEFER. However, currently we
returned -EPROBE_DEFER in the former situation, and ignored the latter
situation (which will lead to the kernel to panic).
Fix the behavior on abnormal base address processing when claiming.

Move this code from arch/arm/mach-tegra and make it common among 32-bit
and 64-bit Tegra SoCs. This is slightly complicated by the fact that on
32-bit Tegra, the SoC device is used as the parent for all devices that
are instantiated from device tree.

Remove unnecessary static on local variables syscon_regmap.
Such variables are initialized before being used, on every
execution path throughout the functions. The static has no
benefit and, removing it reduces the object file size.
This issue was detected using Coccinelle and the following
semantic patch:
@bad exists@
position p;
identifier x;
type T;
@@
static T x@p;
...
x = <+...x...+>
@@
identifier x;
expression e;
type T;
position p != bad.p;
@@
-static
T x@p;
... when != x
when strict
?x = e;
In the following log you can see the difference in the object file size.
This log is the output of the size command, before and after the code
change:

The BPMP firmware, found on Tegra186 and later, provides an ABI that can
be used to enable and disable power to several power partitions in Tegra
SoCs. The ABI allows for enumeration of the available power partitions,
so the driver can be reused on future generations, provided the BPMP ABI
remains stable.

The goals are to:
- Allow precise control over and automatic selection of which
(sub)drivers are used for which SoC,
- Allow adding support for new SoCs easily,
- Allow compile-testing of all (sub)drivers,
- Keep driver selection logic in the subsystem-specific Kconfig,
independent from the architecture-specific Kconfig (i.e. no "select"
from arch/arm64/Kconfig.platforms), to avoid dependencies.
This is implemented by:
- Introducing Kconfig symbols for all drivers and sub-drivers,
- Introducing the Kconfig symbol SOC_RENESAS, which is enabled
automatically when building for a Renesas ARM platform, and which
enables all required drivers without interaction of the user, based
on SoC-specific ARCH_* symbols,
- Allowing the user to enable any Kconfig symbol manually if
COMPILE_TEST is enabled,
- Using the new Kconfig symbols instead of the ARCH_* symbols to
control compilation in the Makefile,
- Always entering drivers/soc/renesas/ during the build.

Don't use size if info indicates an error condition. Previously a
non-ENOENT error (such as -EPROBE_DEFER) would lead to size being used

We had a small batch of fixes before -rc1, but here is a larger one. It
contains a backmerge of 4.12-rc1 since some of the downstream branches we
merge had that as base; at the same time we already had merged contents
before -rc1 and rebase wasn't the right solution.
A mix of random smaller fixes and a few things worth pointing out:
- We've started telling people to avoid cross-tree shared branches if all
they're doing is picking up one or two DT-used constants from a
shared include file, and instead to use the numeric values on first
submission. Follow-up moving over to symbolic names are sent in right
after -rc1, i.e. here. It's only a few minor patches of this type.
- Linus Walleij and others are resurrecting the 'Gemini' platform, and
wanted a cut-down platform-specific defconfig for it. So I picked that
up for them.
- Rob Herring ran 'savedefconfig' on arm64, it's a bit churny but it helps
people to prepare patches since it's a pain when defconfig and current
savedefconfig contents differs too much.
- Devicetree additions for some pinctrl drivers for Armada that were
merged this window. I'd have preferred to see those earlier but it's not
a huge deail.
The biggest change worth pointing out though since it's touching other
parts of the tree: We added prefixes to be used when cross-including
DT contents between arm64 and arm, allowing someone to #include
<arm/foo.dtsi> from arm64, and likewise. As part of that, we needed
arm/foo.dtsi to work on arm as well. The way I suggested this to Heiko
resulted in a recursive symlink.
Instead, I've now moved it out of arch/*/boot/dts/include, into a shared
location under scripts/dtc. While I was at it, I consolidated so all
architectures now behave the same way in this manner.
Rob Herring (DT maintainer) has acked it. I cc:d most other arch
maintainers but nobody seems to care much; it doesn't really affect them
since functionality is unchanged for them by default.

include in this driver, manifesting as:
CC drivers/soc/fsl/qbman/qman_portal.o

commit was singled out via git bisect.
The header it was implictly relying on getting was dma-mapping.h - so
we explicitly add it here.

The QE_General4 workaround is only valid for the MPC832x and MPC836x
SoCs. The other SoCs that embed a QUICC engine are not affected by this
hardware bug and thus can use the computed divisors (this was
successfully tested on the T1040).
Similalry to what was done in commit 8ce795cb0c ("i2c: mpc: assign the
correct prescaler from SVR") in order to avoid changes in
the device tree nodes of the QE (with maybe a variant of the compatible
property), the PVR reg is read out to find out if the workaround must be
applied or not.

Because of integer computation rounding in u-boot (that sets the QE
brg-frequency DTS prop), the clk value is 99999999 Hz even though it is
100 MHz.
When setting brg clks that are exact divisors of 100 MHz, this small
differnce plays a role and can result in lower clks to be output (for
instance 20 MHz - divide by 5 - results in 16.666 MHz - divide by 6).
This patch fixes that by "forcing" the brg_clk to the nearest kHz when
the difference is below 2 integer rounding errors (i.e. 4).

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.

The same SoC may have different power areas, depending on SoC revision.
One option is to use different sets of power area tables for each SoC
revision. However, if the differences are small, it is much more
space-efficient to have a single set of tables, and fix those up at
runtime instead.
Hence provide a helper to NULLify power areas that do not exist on some
revisions (NULLified power areas are skipped during the registration
phase), and support for an optional initialization callback to e.g. fix
up power area tables.

The r8a7795 SYSC driver manages PM Domains, and thus is initialized from
an early_initcall(). However, this means the driver cannot check the
SoC revision, as the SoC device hasn't been registered yet.

to fix this (renesas-soc.o is listed before rcar-sysc.o in the Makefile).

Introduce a ti_sci_pm_domains driver to act as a generic pm domain
provider to allow each device to attach and associate it's ti-sci-id so
that it can be controlled through the TI SCI protocol.
This driver implements a simple genpd where each device node has a
phandle to the power domain node and also must provide an index which
represents the ID to be passed with TI SCI representing the device using
a single phandle cell. The driver manually parses the phandle to get the
cell value. Through this interface the genpd dev_ops start and stop
hooks will use TI SCI to turn on and off each device as determined by
pm_runtime usage.

Please note that Tegra186 does not support the flowctrl module, so
update the initialisation function such that we do not fall back and
attempt to map the 'hardcoded' address range for Tegra186. Furthermore
64-bit Tegra devices have always had the flowctrl node defined in their
device-tree and so only use the 'hardcoded' addresses for 32-bit Tegra
devices.

The flowctrl driver is required for both ARM and ARM64 Tegra devices
and in order to enable support for it for ARM64, move the Tegra flowctrl
driver into drivers/soc/tegra.
By moving the flowctrl driver, tegra_flowctrl_init() is now called by
via an early initcall and to prevent this function from attempting to
mapping IO space for a non-Tegra device, a test for 'soc_is_tegra()'
is also added.

The Makefiles currently controlling compilation of this code is:
drivers/soc/tegra/Makefile:obj-y += fuse/
drivers/soc/tegra/fuse/Makefile:obj-y += fuse-tegra.o
...meaning that it currently is not being built as a module by anyone.
Lets remove the couple traces of modularity so that when reading the
driver there is no doubt it is builtin-only.
Since module_platform_driver() uses the same init level priority as
builtin_platform_driver() the init ordering remains unchanged with
this commit.

Remove the standalone SMD implementation as we have transitioned the
client drivers to use the RPMSG based one.
Also remove all dependencies on QCOM_SMD from Kconfig files, in order to
keep them selectable in the absence of the removed symbol.

By moving these client drivers to use RPMSG instead of the direct SMD
API we can reuse them ontop of the newly added GLINK wire-protocol
support found in the 820 and 835 Qualcomm platforms.
As the new (RPMSG-based) and old SMD implementations are mutually
exclusive we have to change all client drivers in one commit, to make
sure we have a working system before and after this transition.

It is not really necessary to provide the current .readable_reg
implementation as we know what we're doing in our driver
and the regmap core has already done the partial check for
available maximum regs.

Commit 721cabf6c6 ("soc: imx: move PGC handling to a new GPC driver")
broke the MX6SL GPC power domain support.
It always got the following error:
[ 1.248364] imx-gpc 20dc000.gpc: could not find pgc DT node
This patch adds back the legecy support.

ARRAY_SIZE(imx_gpc_domains) represents all power domains supported
by different SoCs. Driver should use SoC specific of_id_data->num_domains
instead to do power domain index sanity check.
e.g. MX6Q supports two power domains while MX6SL supports three.

Without providing the proper reg_defaults, the regmap registers first
read out may be always 0 if enabling cache, which results in the
following issue we met.
e.g. During driver probe in imx6_pm_domain_power_on():
regmap_read(pd->regmap, pd->reg_offs + GPC_PGC_PUPSCR_OFFS, &val);
The PGC_PUPSCR register val is always 0 but it's actually 0xf01 in HW.
Since GPC registers are tightly related to CPU bring up and may be
changed in bootloader, we don't want to provide defaults.
And the cache really does not save too much for GPC module.
Therefore, simply disable cache to fix the issue and make life easy.

The Exynos Power Management Unit (PMU) drivers contain quite large
static arrays of register values necessary for given Exynos SoC to enter
low power mode. All this data is useless for ARMv8 SoC like
Exynos5433, because the image will not be shared between ARMv7 and
ARMv8.
Add additional Kconfig symbol for selecting the SoC-specific driver
addons thus skipping the useless data in the final image (this is
similar approach to chosen for Exynos clock controller drivers):
- exynos-pmu driver will be compiled on both architectures ARMv7
and ARMv8,
- additional driver_data for ARMv7 SoCs will not be built on ARMv8
and a macro will return NULL for them in of_device_id - this should
be safe as these compatibles cannot match on ARMv7 and driver
anyway handles NULL driver_data,
- on ARMv8 compile only exynos-pmu driver which exposes the
syscon-regmap for PMU address space.
