Merge tag 'for-v3.12/omap-prcm-hwmod' of git://git.kernel.org/pub/scm/linux/kernel/git/pjw/omap-pending into omap-for-v3.12/prcm
Various OMAP PRCM & hwmod fixes and improvements. Notable changes
include:
- a fix for OMAP4 PLL locking to avoid a bootloader dependency that
causes nasty log spew on startup
- AM33xx DEBUGSS support fixes in hwmod data
- OMAP5 mailbox support in hwmod data
Basic test logs are here:
http://www.pwsan.com/omap/testlogs/prcm_a_for_v3.12/20130823125002/
Note that the 3530 failure is due to the mysterious transient serial
issue affecting 3530 for several releases now, which causes a log
parsing failure. PM still seems to work.
