Pull gpio updates from Bartosz Golaszewski:
"There are two new drivers and some changes to GPIO core but mostly
just GPIO driver updates across a wide array of files, adding support
for new models as well as various refactoring changes. Nothing
controversial and everything has spent a good measure of time in
linux-next.

GPIOLIB core:
- shrink the GPIO bus driver stub code
- rework software node support for "undefined" software nodes
- provide and use devm_fwnode_gpiod_get_optional()
- only compile the OF quirk for MT2701 when needed

New drivers:
- add the GPIO driver for ROHM bd72720
- add the gpio-line-mux driver providing 1-to-many mapping for a
single real GPIO

Driver changes:
- refactor gpio-pca9570: use lock guard, add missing headers, use
devres consistently
- add support for a new model (G7 Aspeed sgpiom) to the aspeed-sgpio
driver along with some prerequisite refactoring
- use device_get_match_data() where applicable and save some lines
- add support for more models to gpio-cadence
- add the compatible property to reset-gpio and use it in shared GPIO
management
- drop unnecessary use of irqd_get_trigger_type() in gpio-max77759
- add support for a new variant to gpio-pca953x
- extend build coverage with COMPILE_TEST for more drivers
- constify configfs structures in gpio-sim and gpio-virtuser
- add support for the K3 SoC to gpio-spacemit
- implement the missing .get_direction() callback in gpio-max77620
- add support for Tegra264 to gpio-tegra186
- drop unneeded MODULE_ALIAS() from gpio-menz127

DT bindings:
- document support for the opencores GPIO controller in gpio-mmio
- document new variants for gpio-pca953x

Documentation:
- extensively describe interrupt source detection for gpio-pca953x
and add more models to the list of supported variants"

gpio: Support ROHM BD72720 gpios

The ROHM BD72720 has 6 pins which may be configured as GPIOs. The
GPIO1 ... GPIO5 and EPDEN pins. The configuration is done to OTP at the
manufacturing, and it can't be read at runtime. The device-tree is
required to tell the software which of the pins are used as GPIOs.

Keep the pin mapping static regardless the OTP. This way the user-space
can always access the BASE+N for GPIO(N+1) (N = 0 to 4), and BASE + 5
for the EPDEN pin. Do this by setting always the number of GPIOs to 6,
and by using the valid-mask to invalidate the pins which aren't configured
as GPIOs.

First two pins can be set to be either input or output by OTP. Direction
can't be changed by software. Rest of the pins can be set as outputs
only. All of the pins support generating interrupts.

Support the Input/Output state getting/setting and the output mode
configuration (open-drain/push-pull).

gpio: add gpio-line-mux driver

Add a new driver which provides a 1-to-many mapping for a single real
GPIO using a multiplexer. Each virtual GPIO corresponds to a multiplexer
state which, if set for the multiplexer, connects the real GPIO to the
corresponding virtual GPIO.

This can help in various usecases. One practical case is the special
hardware design of the Realtek-based XS1930-10 switch from Zyxel. It
features two SFP+ ports/cages whose signals are wired directly to the
switch SoC. Although Realtek SoCs are short on GPIOs, there are usually
enough the fit the SFP signals without any hacks.

However, Zyxel did some weird design and connected RX_LOS, MOD_ABS and
TX_FAULT of one SFP cage onto a single GPIO line controlled by a
multiplexer (the same for the other SFP cage). The single multiplexer
controls the lines for both SFP and depending on the state, the
designated 'signal GPIO lines' are connected to one of the three SFP
signals.

Because the SFP core/driver doesn't support multiplexer but needs single
GPIOs for each of the signals, this driver fills the gap between both.
It registers a gpio_chip, provides multiple virtual GPIOs and sets the
backing multiplexer accordingly.

Due to several practical issues, this is input-only and doesn't support
IRQs.

Merge tag 'gpio-updates-for-v6.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux

Pull gpio updates from Bartosz Golaszewski:
"There's one new driver, lots of various updates to existing ones, some
refactoring support for new models and misc tweaks and fixes.

The biggest new feature in GPIO core is adding support for managed,
enable-counted sharing of GPIO pins, something that - until now - was
only hacked around with the GPIOD_FLAGS_BIT_NONEXCLUSIVE request flag
which basically allowed drivers to "fight it out" for the descriptor
and provided no synchronization. It was enabled on Qualcomm platforms
(and thus is enabled on arm64 defconfig) and I plan on removing
GPIOD_FLAGS_BIT_NONEXCLUSIVE once all drivers using it are switched to
the new mechanism.

GPIO core:
- add proper support for shared GPIOs that's aiming to replace the
current sharing mechanism (which provides no synchronization ot
enable counting) and enable it for Qualcomm platforms
- improve the software node GPIO lookup by using the fwnode
representation instead of the software node's name which was prone
to bugs (GPIO controllers don't have to use the software node's
name as their kernel label)
- remove the last user of legacy-of-mm-gpiochip.h and drop the header
- move closer to removing the legacy gpio_request_one() routine
- rename some symbols for consistency
- shrink GPIO printk() helpers by reusing existing code
- remove some redundant kernel messages
- use min() instead of min_t() in GPIO ACPI code
- use system_percpu_wq instead of system_wq in GPIO character device
code

New drivers:
- add a driver for the QIXIS FPGA GPIO controller

Driver improvements:
- use modernized variants of power management macros across a wide
array of drivers in order to avoid having to use the __maybe_unused
attribute
- convert gpio-elkhartlake and reset-gpio to using the auxiliary bus
instead of the platform bus as they are not really described in
firmware
- use lock guards and update symbol prefixes in gpio-mmio
- support the bryx radio interface kit in gpio-mpsse + refactor the
driver
- use software nodes for configuring the reset-gpio driver, including
setting up the reference to the shared "reset" pin
- check and propagate the return value of gpiod_set_value() to
user-space in gpio-virtuser (this was previously not possible as
this function returned void)
- extend the gpio-regmap helper with more features (bypass cache for
aliased inputs, force writes for aliased data registers, add a new
configuration parameter)
- remove unneeded includes from gpio-aspeed and gpio-latch
- add support for Tegra410 to gpio-tegra186
- replace PCI-specific PM with generic device-level PM in gpio-bt8xx
- use dynamic GPIO range allocation in gpio-loongson-64bit
- improve handling of level-triggered interrupts in gpio-pca953x
- add suspend/resume support to gpio-fxl6408
- add support for more models to gpio-menz127
- optimize gpio-mvebu interrupt handling by avoiding unnecessary
calls to mvebu_gpio_irq_handler()
- make locking more consistent in gpio-grgpio

Device-tree bindings:
- document new NXP and Microchip models

Documentation:
- add a comprehensive compatibility and feature list for
gpio-pca953x, which is a great addition as it's probably the most
commonly used GPIO expander driver
- kernel-doc tweaks

Late fixes:
- use BYTE_CTRL_MODE for 2K2000/3000 models in gpio-loongson"

This is a very large set of updates, as well as some more extensive
cleanup work from Morimto-san we've also added a generic SCDA class
driver for SoundWire devices enabling us to support many chips with
no custom code. There's also a batch of new drivers added for both
SoCs and CODECs.

regmap work to support it.
- A *lot* of cleaup and API improvement work from Morimoto-san.
- Lots of work on the existing Cirrus, Intel, Maxim and Qualcomm
drivers.

This also pulls in some gpiolib changes supporting shared GPIOs in the
core there so we can convert some of the ASoC drivers open coding
handling of that to the core functionality.

gpio: improve support for shared GPIOs

Merge series from Bartosz Golaszewski <brgl@bgdev.pl>:

Problem statement: GPIOs are implemented as a strictly exclusive
resource in the kernel but there are lots of platforms on which single
pin is shared by multiple devices which don't communicate so need some
way of properly sharing access to a GPIO. What we have now is the
GPIOD_FLAGS_BIT_NONEXCLUSIVE flag which was introduced as a hack and
doesn't do any locking or arbitration of access - it literally just hand
the same GPIO descriptor to all interested users.

The proposed solution is composed of three major parts: the high-level,
shared GPIO proxy driver that arbitrates access to the shared pin and
exposes a regular GPIO chip interface to consumers, a low-level shared
GPIOLIB module that scans firmware nodes and creates auxiliary devices
that attach to the proxy driver and finally a set of core GPIOLIB
changes that plug the former into the GPIO lookup path.

The changes are implemented in a way that allows to seamlessly compile
out any code related to sharing GPIOs for systems that don't need it.

The practical use-case for this are the powerdown GPIOs shared by
speakers on Qualcomm db845c platform, however I have also extensively
tested it using gpio-virtuser on arm64 qemu with various DT
configurations.

gpio: shared-proxy: implement the shared GPIO proxy driver

Add a virtual GPIO proxy driver which arbitrates access to a single
shared GPIO by multiple users. It works together with the core shared
GPIO support from GPIOLIB and functions by acquiring a reference to a
shared GPIO descriptor exposed by gpiolib-shared and making sure that
the state of the GPIO stays consistent.

In general: if there's only one user at the moment: allow it to do
anything as if this was a normal GPIO (in essence: just propagate calls
to the underlying real hardware driver). If there are more users: don't
allow to change the direction set by the initial user, allow to change
configuration options but warn about possible conflicts and finally:
treat the output-high value as a reference counted, logical "GPIO
enabled" setting, meaning: the GPIO value is set to high when the first
user requests it to be high and back to low once the last user stops
"voting" for high.

gpiolib: implement low-level, shared GPIO support

This module scans the device tree (for now only OF nodes are supported
but care is taken to make other fwnode implementations easy to
integrate) and determines which GPIO lines are shared by multiple users.
It stores that information in memory. When the GPIO chip exposing shared
lines is registered, the shared GPIO descriptors it exposes are marked
as shared and virtual "proxy" devices that mediate access to the shared
lines are created. When a consumer of a shared GPIO looks it up, its
fwnode lookup is redirected to a just-in-time machine lookup that points
to this proxy device.

This code can be compiled out on platforms which don't use shared GPIOs.

Layerscape boards such as LX2160ARDB and LS1046AQDS. This driver is

A GPIO controller has a maximum of 8 lines (all found in the same
register). Even within the same controller, the GPIO lines' direction is
fixed, which mean that both input and output lines are found in the same
register. This is why the driver also passed to gpio-regmap the newly
added .fixed_direction_output bitmap to represent the true direction of
the lines.
