[PATCH 0/7] riscv: sophgo: Add pinctrl support for CV1800 series SoC

[Inochi Amaoto]

Add basic pinctrl driver for Sophgo CV1800 series SoCs.
This patch series aims to replace the previous patch from Jisheng [1].
Since the pinctrl of cv1800 has nested mux and its pin definination
is discrete, it is not suitable to use "pinctrl-single" to cover the
pinctrl device.

Note: As current documentation is not enough to guess the pin
configuration of Huashan Pi, only the pinctrl node is added.
