Paul Mundt	b72421d8aa	sh: pfc: support pinmux deregistration. ... Presently the pinmux code is a one-way thing, but there's nothing preventing an unregistration if no one has grabbed any of the pins. This will permit us to save a bit of memory on systems that require pin demux for certain peripherals in the case where registration of those peripherals fails, or they are otherwise not attached to the system.

Magnus Damm	fae4339919	sh: Break out SuperH PFC code ... This file breaks out the SuperH PFC code from arch/sh/kernel/gpio.c + arch/sh/include/asm/gpio.h to drivers/sh/pfc.c + include/linux/sh_pfc.h. Similar to the INTC stuff. The non-SuperH specific file location makes it possible to share the code between multiple architectures.
