[PATCH 2/7] pinctrl: sophgo: add support for CV1800B SoC
Inochi Amaoto

Wed Jul 3 22:46:38 PDT 2024
Sophgo CV1800 series SoCs share common control logic but have
different register mapping. For maintenance, split the driver
and pin definition of the SoC.
Add base driver for CV1800 series SoC and pin definition of
CV1800B.
