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: http://www.pwsan.com/omap/testlogs/prcm-a-for-v3.15/20140228124518/ * 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 Signed-off-by: Olof Johansson <olof@lixom.net>
