gpio: mockup: add a dummy irqchip

2017-02-13T07:35:33+00:00

Setup a dummy irqchip that will allow us to inject line events for
testing purposes.

gpio: Add GPIO support for the ACCES PCI-IDIO-16

2017-02-06T10:01:06+00:00

The ACCES PCI-IDIO-16 device provides 32 lines of digital I/O (16 lines
of optically-isolated digital inputs for AC and DC control signals, and
16 lines of solid state switch digital outputs). 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.

gpio: mcp23s08: Select REGMAP/REGMAP_I2C to fix build error

2017-02-04T20:25:28+00:00

This driver now using devm_regmap_init/devm_regmap_init_i2c, so it needs
to select REGMAP/REGMAP_I2C accordingly.

gpio: exar: add gpio for exar cards

2017-01-26T10:11:40+00:00

Exar XR17V352/354/358 chips have 16 multi-purpose inputs/outputs which
can be controlled using gpio interface.

Add the gpio specific code.

gpio: Add a driver for Cortina Systems Gemini GPIO

2017-01-26T09:00:24+00:00

This is a heavy edit/rewrite of the GPIO driver for the Gemini
SoC from arch/arm/mach-gemini/gpio.c.

This rewrite uses all the best-in-class helper like generic
GPIO and GPIOLIB_IRQCHIP and has been tested on ITian Square One
Gemini-based NAS/router.

Merge tag 'gpio-v4.10-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio

2016-12-13T15:54:57+00:00

Pull GPIO updates from Luinus Walleij:
 "Bulk GPIO changes for the v4.10 kernel cycle:

  Core changes:

   - Simplify threaded interrupt handling: instead of passing numbed
     parameters to gpiochip_irqchip_add_chained() we create a new call:
     gpiochip_irqchip_add_nested() so the two types are clearly
     semantically different. Also make sure that all nested chips call
     gpiochip_set_nested_irqchip() which is necessary for IRQ resend to
     work properly if it happens.

   - Return error on seek operations for the chardev.

   - Clamp values set as part of gpio[d]_direction_output() so that
     anything != 0 will be send down to the driver as "1" not the value
     passed in.

   - ACPI can now support naming of GPIO lines, hogs and holes in the
     GPIO lists.

  New drivers:

   - The SX150x driver was deemed unfit for the GPIO subsystem and was
     moved over to a combined GPIO+pinctrl driver in the pinctrl
     subsystem.

  New features:

   - Various cleanups to various drivers"

gpio: Remove GPIO_DEVRES option

2016-11-16T19:46:32+00:00

This option was added in 6a89a314ab107a12af08c71420c19a37a30fc2d3 to
allow use of the devm_gpio_* functions without CONFIG_GPIOLIB.

However, only a few months later in
b69ac52449c658b7ac40034dc3c5f5f4a71a723d, CONFIG_GPIOLIB was added
as a dependency, defeating the original purpose of this option.
Instead of that patch, the original commit could have just been
reverted (and in fact was partially so in
403c1d0be5ccbd750d25c59d8358843a81e52e3b). Further, since this
option has a dependency on HAS_IOMEM, even though it does not
require it, it causes build failures when !HAS_IOMEM (e.g. in a
uml build).

Fix that by completely removing the option, in essence completing
the reversion of the original commit.
