ea9975c221 pinctrl: fix kismet issues with GENERIC_PINCTRL
lkp reported that GENERIC_PINCTRL can be select when its dependencies
are not. Swap the "depends on" out for "select", as is used in other
parts of the pinctrl core that are expected to be selected by drivers.

43722575e5 pinctrl: add generic functions + pins mapper
Add a generic function to allow creation of groups and functions at
runtime based on devicetree content, before setting up mux mappings.
It works similarly to pinconf_generic_dt_node_to_map(), and
therefore parses pinconf properties and maps those too, allowing it
to be used as the dt_node_to_map member of the pinctrl_ops struct.

a035b23b59 pinctrl: fix compile test defaults
Enabling compile testing should not enable every individual driver (we
have "allyesconfig" for that) but two new drivers got this wrong.

Default to n instead of ARCH_MICROCHIP as these drivers are not needed
in every Microchip build either.

5fb0249319 Pin control changes for the v6.18 kernel cycle:
Core changes:
 
 - Allow pins to be identified/marked as GPIO mode with
   a special callback. The pin controller core is now
   "aware" if a pin is in GPIO mode if the callback is
   implemented in the driver, and can thus be marked
   as "strict", i.e. disallowing simultaneous use of a
   line as GPIO and another function such as I2C. This
   is enabled in the Qualcomm TLMM driver and also
   implemeted from day 1 in the new Broadcom STB driver.
 
 - Rename the pin config option PIN_CONFIG_OUTPUT to
   PIN_CONFIG_LEVEL to better describe what the config is
   doing, as well as making it more intuitive what shall
   be returned when reading this property.
 
 New drivers:
 
 - Qualcomm SDM660 LPASS LPI TLMM pin controller subdriver.
 
 - Qualcomm Glymur family pin controller driver.
 
 - Broadcom STB family pin controller driver.
 
 - Tegra186 pin controller driver.
 
 - AAEON UP pin controller support. This is some special
   pin controller that works as an external advanced line
   MUX and amplifier for signals from an Intel SoC.
   A cooperative effort with the GPIO maintainer was
   needed to reach a solution where we reuse code from
   the GPIO aggregator/forwarder driver.
 
 - Renesas RZ/T2H and RZ/N2H pin controller support.
 
 - Axis ARTPEC-8 subdriver for the Samsung pin controller
   driver.
 
 Improvements:
 
 - Output enable (OEN) support in the Renesas RZG2L driver.
 
 - Properly support bias pull up/down in the pinctrl-single
   driver.
 
 - Move over all GPIO portions using generic MMIO GPIO to
   the new generic GPIO chip management which has a nice and
   separate API.
 
 - Proper DT bindings for some older Broadcom SoCs.
 
 - External GPIO (EGPIO) support in the Qualcomm SM8250.
 
 Deleted code:
 
 - Dropped the now unused Samsung S3C24xx drivers.

a6a2f50ab1 pinctrl: eswin: Fix regulator error check and Kconfig dependency
Smatch reported the following warning in eic7700_pinctrl_probe():

  drivers/pinctrl/pinctrl-eic7700.c:638 eic7700_pinctrl_probe()
  warn: passing zero to 'PTR_ERR'

The root cause is that devm_regulator_get() may return NULL when
CONFIG_REGULATOR is disabled. In such case, IS_ERR_OR_NULL() triggers
PTR_ERR(NULL) which evaluates to 0, leading to passing a success code
as an error.

However, this driver cannot work without a regulator. To fix this:

 - Change the check from IS_ERR_OR_NULL() to IS_ERR()
 - Update Kconfig to explicitly select REGULATOR and
   REGULATOR_FIXED_VOLTAGE, ensuring that the regulator framework is
   always available.

This resolves the Smatch warning and enforces the correct dependency.

dca2f73cf1 pinctrl: Add pin controller driver for AAEON UP boards
This enables the pin control support of the onboard FPGA on AAEON UP

This FPGA acts as a level shifter between the Intel SoC pins and the pin

----------+          +--------------+             +---+

For most of the pins, the FPGA opens/closes a switch to enable/disable
the access to the SoC pin from a pin header.
Each switch, has a direction flag that is set depending the status of the
SoC pin.

For some other pins, the FPGA acts as a mux, and routes one pin (or the
other one) to the header.

The driver also provides a GPIO chip. It requests SoC pins in GPIO mode,
and drives them in tandem with FPGA pins (switch/mux direction).

This commit adds support only for UP Squared board.

 - Eswin EIC7700 pin control support.
 
 - Qualcomm PMIV0104, PM7550 and Milos pin control

   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.

d295ad7ef0 pinctrl: aw9523: Make the driver tristate
The AW9523 driver fails to build in some allmod configs since the
I2C core can be a module, but AW9523 can not. Fix it up by allowing
AW9523 to be a module (tristate).

576623d706 pinctrl: Add driver for Awinic AW9523/B I2C GPIO Expander
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.

37c646dc51 pinctrl: Add support for the Lantic PEF2256 pinmux
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.

40ed50cc3d pinctrl: mlxbf3: remove broken Kconfig 'select'
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]:
  - PINCTRL_MLXBF3 [=y] && PINCTRL [=y] && (MELLANOX_PLATFORM [=n] && ARM64 [=y] || COMPILE_TEST [=y])

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