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. --srini > > 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. >
