Subject: chardev: GPIO for SCx200 & PC-8736x: migrate gpio_dump to common module
From: Jim Cromie <jim.cromie@xxxxxxxxx>
Since the meaning of config-bits is the same for scx200 and pc8736x _gpios, we
can share a function to deliver this to user. Since it is called via the
vtable, its also completely replaceable. For now, we keep using printk...
