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
