[PATCH v2 0/3] pinctrl: spacemit: add support for K3 SoC

[Yixun Lan]

This series attempt to add pinctrl support for SpacemiT K3 SoC,

I've removed the RFC tag as the driver is tested on K3 SoC.

The K3 pinctrl IP shares almost same logic with previous K1 SoC generation,
but has different register offset and pin configuration, I've introduced
a pin_to_offset() function to handle the difference of register offset.
for the drive strength and schmitter trigger settings, they are also changed.

The patch #1 try to add pin support which should handle pin mux, while patch #2
adjust drive strength and schmitter trigger settings accordingly for new SoC.
