[PATCH v2 00/22] Add basic pinctrl drivers for JHB100 SoC

[Changhuang Liang]

The JHB100 SoC has 13 pinctrl domains - sys0, sys0h, sys1, sys2, per0, per1,
per2, per2pok, per3, adc0, adc1, emmc, and vga.

In the current series, we will only add the following pinctrl:
 - sys0, sys0h, sys1, sys2
 - per0, per1, per2, per2pok, per3

The remaining pinctrl will be implemented in future series.

This series depends on the series:
https://lore.kernel.org/all/20260508053632.818548-1-changhuang.liang@starfivetech.com/

Change since v1:
- Add new patch 1/2/3
- Remove v1 PATCH 19

PATCH 5:
- Use the generic interface pinctrl_generic_pins_function_dt_node_to_map()
- Use the 3-cell GPIO framework
- Replace custom pinconf with generic pinconf
- Share a single interrupt number across multiple GPIO banks within the
  same domain

PATCH 4/6/8/10/12/14/16/18/20:
- Move pin definitions into the include directory

PATCH 5/7/9/11/13/15/17/19/21:
- Add a "function" mapping table

PATCH 22:
- Use the 3-cell GPIO framework
- Use pinctrl hog to initialize the pin group voltage.

v1: https://lore.kernel.org/all/20260424111330.702272-1-changhuang.liang@starfivetech.com/
