[U-Boot] [RFC PATCH 0/7] DM: pinctrl: Another implemtation of pinctrl framework

[Masahiro Yamada]

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.



Masahiro Yamada (7):
  pinctrl: add pinctrl framework
  pinctrl: UniPhier: add UniPhier pinctrl core support
  pinctrl: UniPhier: add UniPhier PH1-LD4 pinctrl driver
  pinctrl: UniPhier: add UniPhier PH1-Pro4 pinctrl driver
  pinctrl: UniPhier: add UniPhier PH1-sLD8 pinctrl driver
  ARM: dts: UniPhier: add nodes for pinctrl devices and pin configs
  ARM: select pinctrl drivers from Kconfig
