Merge tag 'omap-for-v3.15/prcm-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into next/soc
Power, reset and clock related changes via Paul Walmsley <paul@pwsan.com>, via
Tony Lindgren:
Some low-level optimizations and fixes that don't belong in an -rc
series for various OMAP-family chips, targeted for v3.15.
Basic build, boot, and PM test logs are available here:

* tag 'omap-for-v3.15/prcm-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap:
ARM: OMAP3+: DPLL: stop reparenting to same parent if already done
ARM: OMAP2+: clock: fix rate prints
ARM: AM43x: hwmod data: register spinlock OCP interface
ARM: OMAP2+: clockdomain: Reintroduce SW_SLEEP Support
ARM: OMAP2+: AM43xx: implement support for machine restart
