MediaTek SoC's pinconf register usage varies by SoC, So the original code uses V0/V1 to mark different pinconf design. But actually, the real difference is the design of the "pin" itself.
Different SoCs will choose specify "pin design", which we call the "io_type" of the pin.
For a better understanding of mediatek pinctrl design. and make the driver clear and flexible, this patch series changes common parts of mediatek pinctrl driver to support various pinctrl controller designs.
--- v2: fix build fail caused by patch [2/3]
Sam Shih (3): pinctrl: mediatek: rewrite mtk_pinconf_set and related functions pinctrl: mediatek: introduce multiple memory bases support pinctrl: mediatek: add support for different types of IO pins
