Subject: [PATCH v4 0/3] Add pinctrl support for S32 SoC family

Hello,

Here I want to introduce a new patch series, which aims to support IOMUX
functions provided by SIUL2 [System Integration Unit Lite2] on S32 SoCs,
such as S32G2. This series is originally from NXP's implementation on
nxp-auto-linux repo[1] and it will be required by upstream kernel for
supporting a variety of devices on S32 SoCs which need to config PINMUXs,
such as PHYs and MAC controllers.

Thanks,
Chester

Changes in v4:
- dt-bindings:
  - Change the representation of available slew-rate DT values from
    register values to real frequencies.
- driver:
  - Add a mapping table for converting the slew rates to register
    settings.
  - Move driver files into an independent folder drivers/pinctrl/nxp
- Add a MAINTAINER patch.

Changes in v3:
- dt-bindings:
  - Remove the minItems from reg because there's no optional item for
    s32g2.
  - List supported properties of pinmux-node and pincfg-node and add more
    descriptions.
  - Adjust the location of "required:".
  - Fix descriptions and wordings.
  - Rename the yaml file to nxp,s32g2-siul2-pinctrl.yaml.
- Rename pinctrl-s32g.c to pinctrl-s32g2.c
- Adjust Kconfig options [menu-invisible] and names [S32G -> S32G2].
- Add .suppress_bind_attrs
- Drop the .remove callback and replace the module_platform_driver() call
  with builtin_platform_driver()

Changes in v2:
- Move the "nxp,pins" ID range information from DT to the driver.
- dt-bindings:
  - Fix schema issues.
  - Add descriptions for reg entries.
  - Revise the example.
- Refine the compatible name from "nxp,s32g-..." to "nxp,s32g2-...".
- Fix the copyright format suggested by NXP.
