I'd like to propose antoher pinctrl design, which is closer to Linux's one.
1/7 adds the uclass support.
2/7 - 5/7 show how low-level drivers can be implemeted on my SoCs as example.
You can implement them in your own way, but they are often done with architecture-specific operation + SoC-specific pin data.
2/7 is the callbacks commonly used for my SoC family. 3/7-5/7 are SoC-specific data sets.
6/7 shows some examples for device tree implementations.
