linux-toradex.git/include/linux/sh_pfc.h, branch v3.0.16 Linux kernel for Apalis and Colibri modules sh: pfc: support pinmux deregistration. 2010-10-03T18:54:56+00:00 Paul Mundt lethal@linux-sh.org 2010-10-03T18:54:56+00:00 b72421d8aa39724474ec2bfb91e182001f1f25a7 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.

sh: Break out SuperH PFC code 2009-11-30T03:02:53+00:00 Magnus Damm damm@opensource.se 2009-11-27T07:38:01+00:00 fae4339919c741f89f7e293b8c646207e1df28e1 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.
