Merge tag 'omap-for-v3.13/cm-scm-cleanup-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into next/cleanup

From Paul Walmsley <paul@pwsan.com> via Tony Lindgren:

Move some of the OMAP2+ CM and System Control Module direct
register accesses into CM- and System Control
Module-specific "drivers" underneath arch/arm/mach-omap2/.  This
is a prerequisite for moving this code out of arch/arm/mach-omap2/ into
drivers/.

Basic test logs are available here:

http://www.pwsan.com/omap/testlogs/cm_scm_cleanup_a_v3.13/20131019101809/

* tag 'omap-for-v3.13/cm-scm-cleanup-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap:
  ARM: OMAP3: control: add API for setting IVA bootmode
  ARM: OMAP3: CM/control: move CM scratchpad save to CM driver
  ARM: OMAP3: McBSP: do not access CM register directly
  ARM: OMAP3: clock: add API to enable/disable autoidle for a single clock
  ARM: OMAP2: CM/PM: remove direct register accesses outside CM code
  + Linux 3.12-rc4
