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.

This adds a driver for the Faraday Technology FTIDE010
PATA IP block.
When used with the Storlink/Storm/Cortina Systems Gemini
SoC, the PATA interface is accompanied by a PATA<->SATA
bridge, so while the device appear as a PATA controller,
it attaches physically to SATA disks, and also has a
designated memory area with registers to set up the bridge.
The Gemini SATA bridge is separated into its own driver
file to make things modular and make it possible to reuse
the PATA driver as stand-alone on other systems than the
Gemini.

This SATA controller is quite similar to the one present on the DA850
SoC, but the PHY configuration is different and it supports two HBA
ports.
The IP suffers from the same PMP issue the DA850 does - if we enable
PMP but don't use it - softreset fails. Appropriate workaround was

When CONFIG_HWMON is disabled, we now get a link failure:

ahci_imx.c:(.text.imx_ahci_probe+0x304): undefined reference to `devm_thermal_zone_of_sensor_register'
This makes the code calling into the hwmon subsystem compile-time
conditional, and adds a Kconfig dependency to avoid the corner
case of having HWMON=m and AHCI_IMX=y, by forcing AHCI_IMX=m in this
case. The thermal subsystem already has a check in its header, but
that also doesn't cover the THERMAL=m case, so we need a somewhat
complex Kconfig expression to handle all cases.

The dwc_460ex SATA driver has become available on non-powerpc architectures
and may cause randconfig build errors when CONFIG_DMADEVICES is not set

This adds an explcit Kconfig dependency to CONFIG_SATA_DWC so we
cannot run into broken configurations. While it would also be
possible to build the driver with both CONFIG_DMADEVICES
and SATA_DWC_OLD_DMA disabled, that case is not useful because
there is no fallback to PIO mode when the DMA engine is not
usable.

Currently this driver only works with a DesignWare DMA engine which it
registers manually using the second "reg" address range and interrupt
number from the DT node.
This patch makes the driver instead use the "dmas" property if present,
otherwise optionally falling back on the old way so existing device
trees can continue to work.
With this change, there is no longer any reason to depend on the 460EX
machine type so drop that from Kconfig.

AMD Seattle SATA controller mostly conforms to AHCI interface with some
special register to control SGPIO interface. In the case of an AHCI
controller, the SGPIO feature is ideally implemented using the
"Enclosure Management" register of the AHCI controller, but those
registeres are not implemented in the Seattle SoC. Instead SoC
(Rev B0 onwards) provides a 32-bit SGPIO control register which should
be programmed to control the activity, locate and fault LEDs.
The driver is based on ahci_platform driver.

This patch adds ACPI supports for AHCI platform driver, which uses _CLS
method to match the device.
The following is an example of ASL structure in DSDT for a SATA controller,
which contains _CLS package to be matched by the ahci_platform driver:
Device (AHC0) // AHCI Controller
{
Name(_HID, "AMDI0600")
Name (_CCA, 1)
Name (_CLS, Package (3)
{

{
Memory32Fixed (ReadWrite, 0xE0300000, 0x00010000)
Interrupt (ResourceConsumer, Level, ActiveHigh, Exclusive,,,) { 387 }
})
}
Also, since ATA driver should not require PCI support for ATA_ACPI,
this patch removes dependency in the driver/ata/Kconfig.

Use syscon/regmap to configure the smc. This allows to avoid using
at91sam9_smc.h and to compile the driver in a multiplatform configuration.
The driver will still not probe until the proper DT bindings are added. That
binding will include an atmel,smc property that is a phandle to the SMC the CF
controller is connected to.

Commit 84683a7e081f ("sata_dwc_460ex: enable COMPILE_TEST for the
driver") enabled this driver for non-ppc460-ex platforms, but it was
then disabled for ARM and ARM64 by commit 2de5a9c004e9 ("sata_dwc_460ex:
disable compilation on ARM and ARM64") because it's too noisy and
broken.
This disabled is entirely, because it's too noisy on x86-64 too, and
there's no point in disabling architectures one by one. At a minimum,
the code isn't 64-bit clean, and even on 32-bit it is questionable
whether it makes sense.

To test how the driver could be compiled in the non-native environment let's
enable COMPILE_TEST for it. It would be useful for further work.
This patch enables COMPILE_TEST for the driver and fixes compilation errors on

The Marvell Armada 380 SoC includes two AHCI compatible
interfaces. However, like all DMA-capable Marvell interface, they
require special handling to configure MBus windows. Therefore, this
commit adds a new ahci_mvebu driver, which relies on the
libahci_platform.c code recently introduced.
