SG2042 has a simple pinctrl device for all configurable pins.
It supports setting pull up/down, drive strength and input schmitt
trigger.
Add support for SG2042 and SG2044 pinctrl device.
Changed from v1:
- https://lore.kernel.org/all/20241024064356.865055-1-inochiama@gmail.com/
1. Fix the binding documentation error.
2. Refactor the cv18xx code so SG2042 can uses the same code.
3. Add SG2044 pinctrl support as it has the same layout.

When setting pinconf configuration for cv1800 SoC, the driver just writes
the value. It may zero some bits of the pinconf register and cause some
unexpected error. Add a mask to avoid this.

To share DT parsing and vddio code, it is necessary to introduce
some generic data structure to abstract the different cv18xx series
and the incoming sg2042 series.

With generic data structure, it is possible to generalize vddio
operators and DT parsing code of cv18xx pinctrl driver. Introduce
sophgo_cfg_ops callback to allow the driver to adjust the soc
logic and share common code.

Since different series of the Sophgo chip share a common pinctrl data
structure. It is necessary to add a common probe function to alloc
the this data structure. Add pctrl_init callback to allow soc to perform
its own initialization.

SG2042 introduces a simple pinctrl device for all configurable pins.
For the SG2042 pinctl register file, each register (32 bits) is
responsible for two pins, each occupying the upper 16 bits and lower
16 bits of the register. It supports setting pull up/down, drive
strength and input schmitt trigger.
Add support for SG2042 pinctrl device.

SG2044 share the share common control logic with SG2042. So
only pin definition is needed.
Add pin definition driver for SG2044 SoC.

I applied these patches 1-7 to the pinctrl tree and created an immutable
branch:
https://web.git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl.git/log/?h=ib-sophgo
> riscv: dts: sophgo: sg2042: add pinctrl support
Apply this patch to the riscv/SoC tree.
If it is required, that tree can pull in my immutable branch, which
is based on v6.14-rc1.
Yours,
Linus Walleij
