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.
