Introduce airoha-mfd driver in order to load pinctrl and pwm drivers for
EN7581 SoC. airoha-mfd is needed since both pinctrl and pwm drivers
needs to access the same memory block (gpio memory region) to configure
{gio,irq}_chip and pwm functionalities respectively, so model them as
childs of a parent mfd driver.
Current EN7581 pinctrl driver supports the following functionalities:
- pin multiplexing via chip_scu syscon
- pin pull-up, pull-down, open-drain, current strength,
{input,output}_enable, output_{low,high} via chip_scu syscon
- gpio controller
- irq controller
---
Changes in v7:
- pinctrl: cosmetics
- pinctrl: fix compilation warning
- Link to v6: https://lore.kernel.org/r/20241013-en7581-pinctrl-v6-0-2048e2d099c2@kernel.org
Changes in v6:
- pwm: rely on regmap APIs
- pwm: introduce compatible string
- pinctrl: introduce compatible string
- remove airoha-mfd driver
- add airoha,en7581-pinctrl binding
- add airoha,en7581-pwm binding
- update airoha,en7581-gpio-sysctl binding
- Link to v5: https://lore.kernel.org/r/20241001-en7581-pinctrl-v5-0-dc1ce542b6c6@kernel.org
Changes in v5:
- use spin_lock in airoha_pinctrl_rmw instead of a mutex since it can run
in interrupt context
- remove unused includes in pinctrl driver
- since the irq_chip is immutable, allocate the gpio_irq_chip struct
statically in pinctrl driver
- rely on regmap APIs in pinctrl driver but keep the spin_lock local to the
driver
- rely on guard/guard_scope APIs in pinctrl driver
- improve naming convention pinctrl driver
- introduce airoha_pinconf_set_pin_value utility routine
- Link to v4: https://lore.kernel.org/r/20240911-en7581-pinctrl-v4-0-60ac93d760bb@kernel.org
Changes in v4:
- add 'Limitation' description in pwm driver
- fix comments in pwm driver
- rely on mfd->base __iomem pointer in pwm driver, modify register
offsets according to it and get rid of sgpio_cfg, flash_cfg and
cycle_cfg pointers
- simplify register utility routines in pwm driver
- use 'generator' instead of 'waveform' suffix for pwm routines
- fix possible overflow calculating duty cycle in pwm driver
- do not modify pwm state in free callback in pwm driver
- cap the maximum period in pwm driver
- do not allow inverse polarity in pwm driver
- do not set of_xlate callback in the pwm driver and allow the stack to
do it
- fix MAINTAINERS file for airoha pinctrl driver
- fix undefined reference to __ffsdi2 in pinctrl driver
- simplify airoha,en7581-gpio-sysctl.yam binding
- Link to v3: https://lore.kernel.org/r/20240831-en7581-pinctrl-v3-0-98eebfb4da66@kernel.org
Changes in v3:
- introduce airoha-mfd driver
- add pwm driver to the same series
- model pinctrl and pwm drivers as childs of a parent mfd driver.
- access chip-scu memory region in pinctrl driver via syscon
- introduce a single airoha,en7581-gpio-sysctl.yaml binding and get rid
of dedicated bindings for pinctrl and pwm
- add airoha,en7581-chip-scu.yaml binding do the series
- Link to v2: https://lore.kernel.org/r/20240822-en7581-pinctrl-v2-0-ba1559173a7f@kernel.org
Changes in v2:
- Fix compilation errors
- Collapse some register mappings for gpio and irq controllers
- update dt-bindings according to new register mapping
- fix some dt-bindings errors
- Link to v1: https://lore.kernel.org/all/cover.1723392444.git.lorenzo@kernel.org/

This patch adds the chip-scu document bindings for EN7581 SoC.
The airoha chip-scu block provides a configuration interface for clock,
io-muxing and other functionalities used by multiple controllers (e.g.
clock, pinctrl, ecc.) on EN7581 SoC.

Introduce pinctrl driver for EN7581 SoC. Current EN7581 pinctrl driver
supports the following functionalities:
- pin multiplexing
- pin pull-up, pull-down, open-drain, current strength,
{input,output}_enable, output_{low,high}
- gpio controller
- irq controller

Hi, thanks for the review. I'm keeping the strange name and renaming
this to "airoha,74hc595-mode".
Contrary to the confusing (taken from documentation) register name,
this actually select what shift register chip is used with 0 as 74HC164
and 1 as 74HC595. The main difference between the 2 chip is the fact
that a latch pin needs to be triggered to the configuration to be
applied. This is handled internally by the SoC but require the correct
chip used in the device to be set in this register, hence the more
descriprtive property. Hope it's O.K.
(Off-topic and sorry for asking, any chance you can help and check also
the clock driver series? It's just some small fixup and regmap
conversion due to EN7581 strange registry mapping. [1]

ack, I will fix them.
