Core changes:
- Open code PINCTRL_FUNCTION_DESC() instead of defining
a complex macro only used in one place.
- Add pinmux_generic_add_pinfunction() helper and
use this in a few drivers.
New drivers:
- Amlogic S7, S7D and S6 pin control support.
- Eswin EIC7700 pin control support.
- Qualcomm PMIV0104, PM7550 and Milos pin control
support.
Because of unhelpful numbering schemes, the Qualcomm
driver now needs to start to rely on SoC codenames.
- STM32 HDP pin control support.
- Mediatek MT8189 pin control support.
Improvements:
- Switch remaining pin control drivers over to the
new GPIO set callback that provides a return value.
- Support RSVD (reserved) pins in the STM32 driver.
- Move many fixed assignments over to pinctrl_desc
definitions.
- Handle multiple TLMM regions in the Qualcomm driver.

The Awinic AW9523(B) is a multi-function I2C gpio expander in a
TQFN-24L package, featuring PWM (max 37mA per pin, or total max
power 3.2Watts) for LED driving capability.
It has two ports with 8 pins per port (for a total of 16 pins),
configurable as either PWM with 1/256 stepping or GPIO input/output,
1.8V logic input; each GPIO can be configured as input or output
independently from each other.
This IC also has an internal interrupt controller, which is capable
of generating an interrupt for each GPIO, depending on the
configuration, and will raise an interrupt on the INTN pin to
advertise this to an external interrupt controller.

The Lantiq PEF2256 is a framer and line interface component designed to
fulfill all required interfacing between an analog E1/T1/J1 line and the
digital PCM system highway/H.100 bus.
This kind of component can be found in old telecommunication system.
It was used to digital transmission of many simultaneous telephone calls
by time-division multiplexing. Also using HDLC protocol, WAN networks
can be reached through the framer.
This pinmux support handles the pin muxing part (pins RP(A..D) and pins
XP(A..D)) of the PEF2256.

The new pinctrl driver selects GPIO_MLXBF3, but that can not be enabled yet because
the MELLANOX_PLATFORM symbol does not exist in the tree:
WARNING: unmet direct dependencies detected for GPIO_MLXBF3
Depends on [n]: GPIOLIB [=y] && PCI [=n] && (MELLANOX_PLATFORM [=n] && ARM64 [=y] || COMPILE_TEST [=y])
Selected by [y]:

As it turns out, the pinctlr driver still builds fine without this, so just
remove the select statement.

Add support for cypress I2C GPIO expanders cy8c9520, cy8c9540 and

The chip features multiple drive modes for each pin when configured
as output and multiple bias settings when configured as input.

It was observed that by allowing pinctrl_amd to be loaded
later in the boot process that interrupts sent to the GPIO
controller early in the boot are not serviced. The kernel treats
these as a spurious IRQ and disables the IRQ.
This problem was exacerbated because it happened on a system with
an encrypted partition so the kernel object was not accesssible for
an extended period of time while waiting for a passphrase.
To avoid this situation from occurring, stop allowing pinctrl-amd
from being built as a module and instead require it to be built-in
or disabled.

Merge tag 'pinctrl-v5.17-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl
Pull pin control bulk updates from Linus Walleij:
"Core changes:
- New standard enumerator and corresponding device tree bindings for
output impedance pin configuration. (Implemented and used in the
Renesas rzg2l driver.)
- Cleanup of Kconfig and Makefile to be somewhat orderly and
alphabetic.
New drivers:
- Samsung Exynos 7885 pin controller.
- Ocelot LAN966x pin controller.
- Qualcomm SDX65 pin controller.
- Qualcomm SM8450 pin controller.
- Qualcomm PM8019, PM8226 and PM2250 pin controllers.
- NXP/Freescale i.MXRT1050 pin controller.
- Intel Thunder Bay pin controller.
Enhancements:
- Introduction of the string library helper function
"kasprintf_strarray()" and subsequent use in Rockchip, ST and
Armada pin control drivers, as well as the GPIO mockup driver.
- The Ocelot pin controller has been extensively rewritten to use
regmap and other modern kernel infrastructure.
- The Microchip SGPIO driver has been converted to use regmap.
- The SPEAr driver had been converted to use regmap.
- Substantial cleanups and janitorial on the Apple pin control driver
that was merged for v5.16.
- Janitorial to remove of_node assignments in the GPIO portions that
anyway get this handled in the GPIO core.
- Minor cleanups and improvements in several pin controllers"
