to here are specific to sm8250, so it should not be in header file to start with.

As these are common to all lpass variants.. I feel it's better to keep in Header file.

You realize that every include of this file will add these static variables to file, in this case to pinctrl-lpass-lpi.c, pinctrl-sm8250-lpass-lpi.c and pinctrl-sc7280-lpass-lpi.c
so in first file(pinctrl-lpass-lpi.c) you never use those variables in second file (pinctrl-sm8250-lpass-lpi.c)you only use up to gpio13 and in third file pinctrl-sc7280-lpass-lpi.c you could use them.

so its really bad idea to add static variables in header files.

Okay. Understood. will move it SoC specific files.

And if new pins comes in later variants, we can add them incrementally, and they will not impact existing pin numbers.

I think in upcoming variants number of pins will not decrease.
