The PIT timer in the 5208 ColdFire has slightly different interrupt bit definitions than the PIT timer used on other ColdFire parts. Define the commonly used bit and mask numbers here, and let part specific defines take precedence if they are defined. Patch originally from Matt Wadell (from code originally written by Mike Lavender). Signed-off-by: Greg Ungerer <gerg@uclinux.com> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
