According to this it uses both PIO and MMIO:
$ git grep '\(in\|out\|read\|write\)\(b\|w\|l\)'
drivers/net/can/sja1000/sja1000_isa.c
drivers/net/can/sja1000/sja1000_isa.c: return readb(priv->reg_base + reg);
drivers/net/can/sja1000/sja1000_isa.c: writeb(val, priv->reg_base + reg);
drivers/net/can/sja1000/sja1000_isa.c: return inb((unsigned
long)priv->reg_base + reg);
drivers/net/can/sja1000/sja1000_isa.c: outb(val, (unsigned long)priv->reg_base
+ reg);
drivers/net/can/sja1000/sja1000_isa.c: outb(reg, base);
drivers/net/can/sja1000/sja1000_isa.c: return inb(base + 1);
drivers/net/can/sja1000/sja1000_isa.c: outb(reg, base);
drivers/net/can/sja1000/sja1000_isa.c: outb(val, base + 1);
But don't worry about it, I'll make the right Kconfig annotation when I submit
my
patches.
