Core changes:
- The gpiolib MMIO driver has been enhanced to handle two direction
registers, i.e. one register to set lines as input and one register
to set lines as output. It turns out some silicon engineer thinks
the ability to configure a line as input and output at the same
time makes sense, this can be debated but includes a lot of analog
electronics reasoning, and the registers are there and need to
be handled consistently. Unsurprisingly, we enforce the lines to
be either inputs or outputs in such schemes.
- Send in the proper argument value to .set_config() dispatched to
the pin control subsystem. Nobody used it before, now someone
does, so fix it to work as expected.
- The ACPI gpiolib portions can now handle pin bias setting (pull up
or pull down). This has been in the ACPI spec for years and we
finally have it properly integrated with Linux GPIOs. It was based
on an observation from Andy Schevchenko that Thomas Petazzoni's
changes to the core for biasing the PCA950x GPIO expander actually
happen to fit hand-in-glove with what the ACPI core needed.
Such nice synergies happen sometimes.
New drivers:
- A new driver for the Mellanox BlueField GPIO controller. This is
using 64bit MMIO registers and can configure lines as inputs
and outputs at the same time and after improving the MMIO library
we handle it just fine. Interesting.
- A new IXP4xx proper gpiochip driver with hierarchical interrupts
should be coming in from the ARM SoC tree as well.
Driver enhancements:
- The PCA053x driver handles the CAT9554 GPIO expander.
- The PCA053x driver handles the NXP PCAL6416 GPIO expander.
- Wake-up support on PCA053x GPIO lines.
- OMAP now does a nice asynchronous IRQ handling on wake-ups by
letting everything wake up on edges, and this makes runtime PM
work as expected too.
Misc:
- Several cleanups such as devres fixes.
- Get rid of some languager comstructs that cause problems when
compiling with LLVMs clang.
- Documentation review and update.

This patch adds pinctrl/GPIO driver for STMicroelectronics

STMFX is an I2C slave controller, offering up to 24 GPIOs.
The driver relies on generic pin config interface to configure the GPIOs.

Non-critical fixes for Intel Baytrail and Intel Cedarfork.
Couple of fixes for all pinctrl-intel based drivers with regard to
IRQ handling, i.e. moving PM calls to noirq level to avoid IRQ lose
and restore ownership of pins to prevent IRQ masking side effect.
The following is an automated git shortlog grouped by driver:
baytrail:
- Fix potential NULL pointer dereference
cedarfork:
- Update pin names according to v1.13c
intel:
- Increase readability of intel_gpio_update_pad_mode()
- Retain HOSTSW_OWN for requested gpio pin
- move gpio suspend/resume to noirq phase

The touchpad of the ASUS laptops E403NA, X540NA, X541NA are not
responsive after suspend/resume. The following error message
shows after resume.
i2c_hid i2c-ELAN1200:00: failed to reset device.
On these laptops, the touchpad interrupt is connected via a GPIO
pin which is controlled by Intel pinctrl. After system resumes,
the GPIO is in ACPI mode and no longer works as an IRQ.
This commit saves the HOSTSW_OWN value during suspend, make sure
the HOSTSW_OWN mode remains the same after resume.

H6 SoC has a "pio group withstand voltage mode" register (datasheet
description), that needs to be used to select either 1.8V or 3.3V I/O mode,
based on what voltage is powering the respective pin banks and is thus used
for I/O signals.
Add support for configuring this register according to the voltage of the
pin bank regulator (if enabled).
This is similar to the support for I/O bias voltage setting patch for A80
and the same concerns apply. See:

In current driver, SET_LATE_SYSTEM_SLEEP_PM_OPS is used to install the
callbacks for suspend/resume.
GPIO pin may be used as the interrupt pin by some device. However, using
SET_LATE_SYSTEM_SLEEP_PM_OPS() to install the callbacks, the resume
callback is called after resume_device_irqs(). Unintended interrupts may
arrive due to resuming device irqs first, but the GPIO controller is not
properly restored.
Normally, for a SMP system, there are multiple cores, so even when there are
unintended interrupts, BSP gets the chance to initialize the GPIO chip soon.
But when there is only 1 core is active (other cores are offlined or
single core) during resume, it is more easily to observe the unintended
interrupts.
This patch renames the suspend/resume function by adding suffix "_noirq",
and installs the callbacks using SET_NOIRQ_SYSTEM_SLEEP_PM_OPS().

This patch provides the advanced drive for I2C used pins on MT8183.
The detail strength specification description of the I2C pin:
When E1=0/E0=0, the strength is 0.125mA.
When E1=0/E0=1, the strength is 0.25mA.
When E1=1/E0=0, the strength is 0.5mA.
When E1=1/E0=1, the strength is 1mA.
For I2C pins, there are existing generic driving setup and the above
specific driving setup. I2C pins can only support 2/4/6/8/10/12/14/16mA
driving adjustment in generic driving setup. But in specific driving
setup, they can support 0.125/0.25/0.5/1mA adjustment.
If we enable specific driving setup for I2C pins,
the existing generic driving setup will be disabled.
For some special features, we need the I2C pins specific driving setup.
The specific driving setup is controlled by E1E0EN.
So we need add extra vendor driving preperty instead of the generic
driving property. We can add "mediatek,drive-strength-adv = <XXX>;"
to describe the specific driving setup property.
"XXX" means the value of E1E0EN. So the valid arguments of
"mediatek,drive-strength-adv" are from 0 to 7.

The comment for this dbg_show says that it is supposed to return more
than what the generic code is showing, including de-glitching. That's
wrong because:
- this chip does not support deglitching,
- the code does not print anything extra compared to the generic
handler,
- its behavior is different because it skips unrequested GPIOs; the
generic code prints their names if they're assigned
There is an important difference, though. Previously, dbg_show would
re-check some registers to see if they still match what the regmap
thinks should be in there. This was semi-useful when develpoing the HW
board because it immediately pointed to SPI wiring problem if a CS
connection was missing (0xffs are easy to see). However, I do not think
that this makes much sense -- and one could always do this in some other
way if needed.

Our pinctrl drivers are consisting of some common code, and big pin tables
that are SoC-specific. This is fine in most cases, but when you want to
reduce the size of the particular kernel image, those big tables are, well,
quite big.
We haven't had the option to disable them in the past since they were
hidden Kconfig options based on the SoC support. However, that granularity
isn't great since we don't have one Kconfig option per-SoC, but rather one
by family.
Make those options selectable by the user so that they can disable it if
needed, while keeping the current default to not change the standard case.
