There are quite a lot simple GPIO controller which are using regmap to
access the hardware. This driver tries to be a base to unify existing
code into one place. This won't cover everything but it should be a good
starting point.It does not implement its own irq_chip because there is already a
generic one for regmap based devices. Instead, the irq_chip will be
instantiated in the parent driver and its irq domain will be associate
to this driver.For now it consists of the usual registers, like set (and an optional
clear) data register, an input register and direction registers.
Out-of-the-box, it supports consecutive register mappings and mappings
where the registers have gaps between them with a linear mapping between
GPIO offset and bit position. For weirder mappings the user can register
its own .xlate().Signed-off-by: Michael Walle

GPIO controllers are exported to userspace using /dev/gpiochip*
character devices. Access control to these devices is provided by
standard UNIX file system permissions, on an all-or-nothing basis:
either a GPIO controller is accessible for a user, or it is not.
Currently no mechanism exists to control access to individual GPIOs.Hence add a GPIO driver to aggregate existing GPIOs, and expose them as
a new gpiochip.This supports the following use cases:
- Aggregating GPIOs using Sysfs
This is useful for implementing access control, and assigning a set
of GPIOs to a specific user or virtual machine.
- Generic GPIO Driver
This is useful for industrial control, where it can provide
userspace access to a simple GPIO-operated device described in DT,
cfr. e.g. spidev for SPI-operated devices.Signed-off-by: Geert Uytterhoeven

ROHM BD71828 PMIC contains 4 pins which can be configured by OTP
to be used for general purposes. First 3 can be used as outputs
and 4.th pin can be used as input. Allow them to be controlled
via GPIO framework.The driver assumes all of the pins are configured as GPIOs and
trusts that the reserved pins in other OTP configurations are
excluded from control using "gpio-reserved-ranges" device tree
property (or left untouched by GPIO users).Typical use for 4.th pin (input) is to use it as HALL sensor
input so that this pin state is toggled when HALL sensor detects
LID position change (from close to open or open to close). PMIC
HW implements some extra logic which allows PMIC to power-up the
system when this pin is toggled. Please see the data sheet for
details of GPIO options which can be selected by OTP settings.Signed-off-by: Matti Vaittinen

Pull ARM SoC platform updates from Olof Johansson:
"SoC updates, mostly refactorings and cleanups of old legacy platforms.Major themes this release:
- Conversion of ixp4xx to a modern platform (drivers, DT, bindings)
- Moving some of the ep93xx headers around to get it closer to
multiplatform enabled.- Cleanups of Davinci
This also contains a few patches that were queued up as fixes before
5.1 but I didn't get sent in before release"* tag 'armsoc-soc' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (123 commits)

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

GPIO platform driver for the AMD G-series PCH (eg. on GX-412TC)
This driver doesn't registers itself automatically, as it needs to
be provided with platform specific configuration, provided by some
board driver setup code.Didn't implement oftree probing yet, as it's rarely found on x86.

This patch adds a driver for Cadence GPIO controller.
It can be enabled with GPIO_CADENCE Kconfig option.
It uses generic GPIO infrastructure and works
as an interrupt controller.
At the moment it only supports level sensitive irqs.Signed-off-by: Jan Kotas
