Merge branch 'renesas/timer' into next/timer
Conflicts: arch/arm/mach-shmobile/timer.c This resolves a nonobvious merge conflict between renesas timer changes in the global timer changes with those from the renesas soc branch and last minute bug fixes that went into v3.3. Signed-off-by: Arnd Bergmann <arnd@arndb.de>
