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.

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

Thanks, I will take care of the device tree.

This patch is unapplied temporarily for dependency issue.
I will repick it in the next cycle.

Reapply this to the sophgo/for-next.
