[PATCH 0/7] pinctrl: airoha: add AN7589 support

[John Crispin <john@phrozen.org>]

The Airoha AN7589 has a GPIO controller like the EN7581 one, with a
third bank for 74 GPIOs in total. Its pin functions are selected
differently: a separate IOMUX block holds a 4 bit mode field per pin,
eight pins per register, and mode 0 makes any pin a GPIO.

The first four patches prepare the shared driver and change nothing
for the SoCs it serves today:

 1. The GPIO register layout moves into the match data, so a SoC can
    describe more than 64 pins.
 2. A function group can carry one IOMUX mode per pin. A SoC
    describes its IOMUX in the match data: the width of the mode
    field and, from patch 4, the mode that makes a pin a GPIO.
 3. The chip SCU becomes optional, as the AN7589 needs none.
 4. A pin requested by gpiolib is put into GPIO mode through the
    IOMUX, so no per pin gpio function is needed.

Patch 5 adds the bindings for the pin controller and the GPIO system
controller it sits under. Patch 6 moves the GPIO register offsets to
the common header, so the AN7589 data can describe its own register
table, with no functional change. Patch 7 adds the AN7589 pin data.

The series applies to next-20261105 and has no dependencies.

John Crispin (7):
  pinctrl: airoha: make gpio register layout per SoC
  pinctrl: airoha: add per pin mode field mux
  pinctrl: airoha: make the chip SCU optional
  pinctrl: airoha: mux a requested GPIO through the IOMUX
  dt-bindings: pinctrl: airoha: add AN7589
  pinctrl: airoha: move the GPIO register offsets to the common header
  pinctrl: airoha: add support of an7589 SoC
