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 Signed-off-by: Olof Johansson <olof@lixom.net>
