So what about: #define _PORT_GP_CFG_1(bank, pin, fn, sfx, cfg) fn(bank, pin, GP_##bank##_##pin, sfx, cfg) #define _PORT_GP_CFG_2(bank, pin, fn, sfx, cfg) \ _PORT_GP_CFG_1(bank, 0, fn, sfx, cfg) _PORT_GP_CFG_1(bank, 1, fn, sfx, cfg) #define _PORT_GP_CFG_4(bank, pin, fn, sfx, cfg) \ _PORT_GP_CFG_2(bank, 0, fn, sfx, cfg) _PORT_GP_CFG_2(bank, 2, fn, sfx, cfg) ... #define _PORT_GP_CFG_32(bank, pin, fn, sfx, cfg) \ _PORT_GP_CFG_16(bank, 0, fn, sfx, cfg) _PORT_GP_CFG_16(bank, 16, fn, sfx, cfg) All the rest (only the ones we really need) can be defined in terms of the above. E.g. #define PORT_GP_CFG_1(bank, fn, sfx, cfg) _PORT_GP_CFG_1(bank, 0, fn, sfx, cfg) #define PORT_GP_CFG_2(bank, fn, sfx, cfg) _PORT_GP_CFG_2(bank, 0, fn, sfx, cfg) #define PORT_GP_CFG_4(bank, pin, fn, sfx, cfg) _PORT_GP_CFG_4(bank, 0, fn, sfx, cfg) ... #define PORT_GP_CFG_32(bank, fn, sfx, cfg) _PORT_GP_CFG_32(bank, 0, fn, sfx, cfg) and #define PORT_GP_1(bank, fn, sfx) _PORT_GP_CFG_1(bank, 0, fn, sfx, 0) #define PORT_GP_2(bank, fn, sfx) _PORT_GP_CFG_2(bank, 0, fn, sfx, 0) #define PORT_GP_4(bank, fn, sfx) _PORT_GP_CFG_4(bank, 0, fn, sfx, 0) ... #define PORT_GP_32(bank, fn, sfx) _PORT_GP_CFG_32(bank, 0, fn, sfx, 0) and for the special (non-power-of-two) numbers e.g. #define PORT_GP_12(bank, fn, sfx) \ _PORT_GP_CFG_8(bank, 0, fn, sfx, 0) _PORT_GP_CFG_4(bank, 8, fn, sfx, 0) What do you think?

Thanks ! Hmm... I'm tring this, but... Can I confirm ? Your idea was this #define _PORT_GP_CFG_2(bank, pin, fn, sfx, cfg) \ _PORT_GP_CFG_1(bank, 0, fn, sfx, cfg) _PORT_GP_CFG_1(bank, 1, fn, sfx, cfg) But I think you want this ? #define _PORT_GP_CFG_2(bank, pin, fn, sfx, cfg) \ - _PORT_GP_CFG_1(bank, 0, fn, sfx, cfg) _PORT_GP_CFG_1(bank, 1, fn, sfx, cfg) + _PORT_GP_CFG_1(bank, pin, fn, sfx, cfg) _PORT_GP_CFG_1(bank, pin + 1, fn, sfx, cfg) I noticed it seems difficult, because it is based on #define PORT_GP_CFG_1(bank, pin, fn, sfx, cfg) fn(bank, pin, GP_##bank##_##pin, sfx, cfg) ~~~ ~~~ we can't use (pin + x) style.

I think _12 is used in pfc-sh7734.c ? I added _8 because pfc-r8a7779.c is using _9.
