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.

Slightly more changes than usual this time:
- KDump Kernel IOMMU take-over code for AMD IOMMU. The code now
tries to preserve the mappings of the kernel so that master
aborts for devices are avoided. Master aborts cause some
devices to fail in the kdump kernel, so this code makes the
dump more likely to succeed when AMD IOMMU is enabled.
- Common flush queue implementation for IOVA code users. The
code is still optional, but AMD and Intel IOMMU drivers had
their own implementation which is now unified.
- Finish support for iommu-groups. All drivers implement this
feature now so that IOMMU core code can rely on it.
- Finish support for 'struct iommu_device' in iommu drivers. All
drivers now use the interface.
- New functions in the IOMMU-API for explicit IO/TLB flushing.
This will help to reduce the number of IO/TLB flushes when
IOMMU drivers support this interface.

the kdump kernel, so this code makes the dump more likely to
succeed when AMD IOMMU is enabled.
- common flush queue implementation for IOVA code users. The code is
still optional, but AMD and Intel IOMMU drivers had their own

support this interface.

The initialization of MediaTek power manager(SCPSYS) is
builtin_platform_driver, and SMI must depend on power-domain.
Thus, currently subsys_initcall for SMI is unnecessary, SMI will be
always probe defered by power-domain. Degrade it to module_init.
In addition, there are two small changes about the probe sequence:
1) Delete this two lines.
if (!dev->pm_domain)
return -EPROBE_DEFER;
This is not helpful. the platform driver framework guarantee this.
The "dev_pm_domain_attach" in the "platform_drv_probe" will return
EPROBE_DEFER if its powerdomain is not ready.
2) Add the probe-defer for the smi-larb device should waiting for
smi-common.
In mt2712, there are 2 smi-commons, 10 smi-larbs. All will be
probe-defered by the power-domain, there is seldom case that
smi-larb probe done before smi-common. then it will hang like
this:

The M4U IP blocks in mt2712 is MTK's generation2 M4U which use the
ARM Short-descriptor like mt8173, and most of the HW registers are
the same.
The difference is that there are 2 M4U HWs in mt2712 while there's
only one in mt8173. The purpose of 2 M4U HWs is for balance the
bandwidth.
Normally if there are 2 M4U HWs, there should be 2 iommu domains,
each M4U has a iommu domain.

As reported in [1] and in [2] it's not possible to set the device tree
property 'atmel,smc-tdf-ns' to zero, although the SoC allows a setting
of 0ns for the t_DF time.
Allow this setting by doing the same thing as in the atmel nand
controller driver by setting ncycles to ATMEL_SMC_MODE_TDF_MIN if zero
is set in the dts.

Setting optional EBI/SMC properties through device tree always fails due
to wrong evaluation of the return value of
atmel_ebi_xslate_smc_timings().
If you put some of those properties in your dts file, but not
'atmel,smc-tdf-ns' the local variable 'required' in
atmel_ebi_xslate_smc_timings() stays on 'false' after the first 'if'
block. This leads to setting 'ret' to -EINVAL in the first run of the
following 'for' loop which is then the return value of this function.
However if you set 'atmel,smc-tdf-ns' in the dts file and everything in
atmel_ebi_xslate_smc_timings() works well, it returns the content of
'required' which is 'true' then.
So the function atmel_ebi_xslate_smc_timings() always returns non-zero
which lets its call in atmel_ebi_xslate_smc_config() always fail and
thus returning -EINVAL, so the EBI configuration for this node fails.
Judging from the following code evaluating the local 'required' variable
in atmel_ebi_xslate_smc_config() and the call of caps->xlate_config in
atmel_ebi_dev_setup() it's probably right to only let the call fail if a
negative error code is returned.

->suspend()/->resume() hooks.
We can also get rid of those regmap fields (and the associated ->init()
hook) which are not longer needed thanks to the
atmel_[h]smc_cs_conf_{apply,get}() helpers.

As Freescale/NXP IFC controller is available on LS1021A, the dependency
for LS1021A is added.
LS1021A is an earlier product and is not compatible with later
LayerScape architecture. So ARCH_LAYERSCAPE can't cover LS1021A.

Driver updates for ARM SoCs.
A handful of driver changes this time around. The larger changes are:
- Reset drivers for hi3660 and zx2967
- AHCI driver for Davinci, acked by Tejun and brought in here due to
platform dependencies
- Cleanups of atmel-ebi (External Bus Interface)
- Tweaks for Rockchip GRF (General Register File) usage (kitchensink misc
register range on the SoCs)
- PM domains changes for support of two new ZTE SoCs (zx296718 and zx2967)

If 'of_find_device_by_node()' fails, an 'of_node_put()' call is missing in

TI aemif driver creates its own subnodes of the device tree in order
to guarantee that all child devices are probed after the AEMIF timing
parameters are configured.
Some devices (e.g. da850) use struct of_dev_auxdata for clock lookup
but nodes created from within the aemif driver can't access the lookup
table.
Create a platform data structure that holds a pointer to
of_dev_auxdata so that we can use it with of_platform_populate().
