This adds a driver for the IXP4xx GPIO block found in
the Intel XScale IXP4xx systems.The GPIO part of this block is pretty straight-forward and
just uses the generic MMIO GPIO library.The irqchip side of this driver is hierarchical where
the main irqchip will receive a processed level trigger
in response to the edge detector of the GPIO block,
so for this reason the v2 version of the irqdomain API
is used (as well as in the parent IXP4xx irqchip) and
masking, unmasking and setting up the type on IRQ
happens on several levels.Currently this GPIO controller will grab the parent
irqdomain using a special function, but as the platform
move toward device tree probing, this will not be needed:
we can just look up the parent irqdomain from the device
tree.Cc: Bartosz Golaszewski

The Nintendo Wii's chipset (called "Hollywood") has a GPIO controller

some special mechanisms to share the controller between the system's

not supported.This patch adds a basic driver for this GPIO controller. Interrupt
support will come in a later patch.This patch is based on code developed by Albert Herranz and the GameCube

The ACCES PCIe-IDIO-24 device provides 56 lines of digital I/O (24 lines
of optically-isolated non-polarized digital inputs for AC and DC control
signals, 24 lines of isolated solid state FET digital outputs, and 8
non-isolated TTL/CMOS compatible programmable I/O). An interrupt is
generated when any of the inputs change state (low to high or high to
low).Input filter control is not supported by this driver, and input filters
are deactivated by this driver. These devices are capable of
get_multiple and set_multiple functionality, but these functions have
not yet been implemented for this driver. Change-Of-State (COS)
detection functionality may be configured to fire interrupts on
exclusively rising/falling edges, but this driver currently only
implements COS detection for either both edges or none.Signed-off-by: William Breathitt Gray

Currently, only W83627UHG model (also known as Nuvoton NCT6627UD)
is supported but in the future a support for other Winbond models,
too, can be added to the driver.A module parameter "gpios" sets a bitmask of GPIO ports to enable

might be managed by the firmware (for functions like powering on and
off, sleeping, BIOS recovery, etc.) and some of GPIO port pins are
physically shared with other devices included in the Super I/O chip.Signed-off-by: Maciej S. Szmigiero

Pull GPIO updates from Linus Walleij:
"This is the bulk of GPIO changes for the v4.15 kernel cycle:Core:
- Fix the semantics of raw GPIO to actually be raw. No inversion
semantics as before, but also no open draining, and allow the raw
operations to affect lines used for interrupts as the caller
supposedly knows what they are doing if they are getting the big
hammer.- Rewrote the __inner_function() notation calls to names that make
more sense. I just find this kind of code disturbing.- Drop the .irq_base() field from the gpiochip since now all IRQs are
mapped dynamically. This is nice.- Support for .get_multiple() in the core driver API. This allows us
to read several GPIO lines with a single register read. This has
high value for some usecases: it can be used to create
oscilloscopes and signal analyzers and other things that rely on
reading several lines at exactly the same instant. Also a generally
nice optimization. This uses the new assign_bit() macro from the
bitops lib that was ACKed by Andrew Morton and is implemented for
two drivers, one of them being the generic MMIO driver so everyone
using that will be able to benefit from this.- Do not allow requests of Open Drain and Open Source setting of a
GPIO line simultaneously. If the hardware actually supports
enabling both at the same time the electrical result would be
disastrous.- A new interrupt chip core helper. This will be helpful to deal with
"banked" GPIOs, which means GPIO controllers with several logical
blocks of GPIO inside them. This is several gpiochips per device in
the device model, in contrast to the case when there is a 1-to-1
relationship between a device and a gpiochip.New drivers:
- Maxim MAX3191x industrial serializer, a very interesting piece of
professional I/O hardware.- Uniphier GPIO driver. This is the GPIO block from the recent
Socionext (ex Fujitsu and Panasonic) platform.- Tegra 186 driver. This is based on the new banked GPIO
infrastructure.Other improvements:
- Some documentation improvements.
- Wakeup support for the DesignWare DWAPB GPIO controller.
- Reset line support on the DesignWare DWAPB GPIO controller.

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

This GPIO controller is used on UniPhier SoC family.
It also serves as an interrupt controller, but interrupt signals are
just delivered to the parent irqchip without any latching or OR'ing.
This type of hardware can be well described with hierarchy IRQ domain.One unfortunate thing for this device is that the interrupt mapping to
the interrupt parent is not contiguous.I asked how DT can describe interrupt mapping between two irqchips [1],
but I could not find a good solution (at least in the framework level).
In fact, irqchip drivers using hierarchy domain generally hard-code the
DT binding of their parent.After tackling on several approaches such as hard-code of hwirqs,
irq_domain_push_irq(), I ended up with a vendor specific property.
If we come up with a good idea to support this in the framework, we
can migrate over to it, but we can live with a driver-level solution
for now.[1] https://lkml.org/lkml/2017/7/6/758

This patch adds support for TPS68470 GPIOs.
There are 7 GPIOs and a few sensor related GPIOs.
These GPIOs can be requested and configured as
appropriate.The GPIOs are also provided with descriptive names.
However, the typical use case is that the OS GPIO
driver will interact with TPS68470 GPIO driver
to configure these GPIOs, as requested by the
platform firmware.Signed-off-by: Rajmohan Mani

Pull GPIO updates from Linus Walleij:
"This is the bulk of GPIO changes for the v4.13 series.Some administrativa:
I have a slew of 8250 serial patches and the new IOT2040 serial+GPIO
driver coming in through this tree, along with a whole bunch of Exar
8250 fixes. These are ACKed by Greg and also hit drivers/platform/*
where they are ACKed by Andy Shevchenko.Speaking about drivers/platform/* there is also a bunch of ACPI stuff
coming through that route, again ACKed by Andy.The MCP23S08 changes are coming in here as well. You already have the
commits in your tree, so this is just a result of sharing an immutable
branch between pin control and GPIO.Core:
- Export add/remove for lookup tables so that modules can export GPIO
descriptor tables.
- Handle GPIO sleep states: it is now possible to flag that a GPIO
line may loose its state during suspend/resume of the system to
save power. This is used in the Wolfson Micro Arizona driver.
- ACPI-based GPIO was tightened up a lot around the edges.
- Use bitmap_fill() to speed up a loop.New drivers:
- Exar XRA1403 SPI-based GPIO.
- MVEBU driver now supports Armada 7K and 8K.
- LP87565 PMIC GPIO.
- Renesas R-CAR R8A7743 (RZ/G1M).
- The new IOT2040 8250 serial/GPIO also comes in through this
changeset.Substantial driver changes:
- Seriously fix the Exar 8250 GPIO portions to work.
- The MCP23S08 was moved out to a pin control driver.
- Convert MEVEBU to use regmap for register access.
- Drop Vulcan support from the Broadcom driver.
- Serious cleanup and improvement of the mockup driver, giving us a
better test coverage.Misc:
- Lots of janitorial clean up.
- A bunch of documentation fixes"* tag 'gpio-v4.13-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio: (70 commits)
