Add SPDX license identifiers to all Make/Kconfig files which:
- Have no license information of any form
These files fall under the project license, GPL v2 only. The resulting SPDX
license identifier is:GPL-2.0-only

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

Delete the Gemini boardfiles: we have corresponding, fully-featured

This adds initial and compulsory device tree support to the
Gemini ARMv4 platform.We are selecting a bunch of "absolute minimals" for getting a working
system up with just device tree:- We select USE_OF for natural reasons or nothing works.
- We select CLKSRC_OF and GEMINI_TIMER so we get timekeeping from
the clocksource.- We select GPIO_GEMINI because these are used as irqchips, and
for a generic driver it is not reasonable for those to have to
select every possible irqchip in the world to work, the platform
should simply provide the available irqchips.- We select a UART that can be exprected to work with
SERIAL_OF_PLATFORM which is the name for an 8250 OF-probed
serial port.- We select the syscon-based reset controller: it's not fun when
"reboot" doesn't work because of Kconfig, so we just select
POWER_RESET and POWER_RESET_SYSCON.- We perhaps a bit controversiallt select ARM_APPENDED_DTB, because
this platform is using the ancient RedBoot, and can *NOT* be
expected to upgrade its bootloaders. Appended device tree is
simply how these devices have to work with device tree.Cc: Janos Laube

set_irq_flags is ARM specific with custom flags which have genirq
equivalents. Convert drivers to use the genirq interfaces directly, so we
can kill off set_irq_flags. The translation of flags is as follows:IRQF_VALID -> !IRQ_NOREQUEST
IRQF_PROBE -> !IRQ_NOPROBE
IRQF_NOAUTOEN -> IRQ_NOAUTOENFor IRQs managed by an irqdomain, the irqdomain core code handles clearing
and setting IRQ_NOREQUEST already, so there is no need to do this in
.map() functions and we can simply remove the set_irq_flags calls. Some
users also modify IRQ_NOPROBE and this has been maintained although it
is not clear that is really needed. There appears to be a great deal of
blind copy and paste of this code.Signed-off-by: Rob Herring

Pull GPIO changes from Linus Walleij:
"Here is the bulk of GPIO changes for the v3.13 development cycle.I've got ACKs for the things that affect other subsystems (or it's my
own subsystem, like pinctrl). Most of that pertain to an attempt from
my side to consolidate and get rid of custom GPIO implementations in
the ARM tree. I will continue doing this.The main change this time is the new GPIO descriptor API, background
for this can be found in Corbet's summary from this january in LWN:http://lwn.net/Articles/533632/
Summary:
- Merged the GPIO descriptor API from Alexandre Courbot. This is a
first step toward trying to get rid of the global GPIO numberspace
for the future.- Add an API so that driver can flag that a certain GPIO line is
being used by a irqchip backend for generating IRQs, so that we can
enforce checks, like not allowing users to switch that line to an
output at runtime, since this makes no sense. Implemented
corresponding calls in a few select drivers.- ACPI GPIO cleanups, refactorings and switch to using the
descriptor-based interface.- Support for the TPS80036 Palmas GPIO variant.
- A new driver for the Broadcom Kona GPIO SoC IP block.
- Device tree support for the PCF857x driver.
- A set of ARM GPIO refactorings with the goal of getting rid of a
bunch of custom GPIO implementations from the arch/arm/* tree:* Move the IOP GPIO driver to the GPIO subsystem and fix all users
to use the gpiolib API for accessing GPIOs. Delete the old
custom GPIO implementation.* Delete the unused custom PXA GPIO implemention.
* Convert all users of the IXP4 custom GPIO implementation to use
gpiolib and delete the custom implementation.* Delete the custom Gemini GPIO implementation, also completely
unused.- Various cleanups and renamings"
