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.
Inochi Amaoto (8):
pinctrl: sophgo: avoid to modify untouched bit when setting cv1800
pinconf
pinctrl: sophgo: introduce generic data structure for cv18xx pinctrl
driver
pinctrl: sophgo: generalize shareable code of cv18xx pinctrl driver
pinctrl: sophgo: introduce generic probe function
dt-bindings: pinctrl: Add pinctrl for Sophgo SG2042 series SoC
pinctrl: sophgo: add support for SG2042 SoC
pinctrl: sophgo: add support for SG2044 SoC
riscv: dts: sophgo: sg2042: add pinctrl support
