Merge tag 'omap-for-v3.9/am33xx-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into late/omap

From Tony Lindgren:
am33xx updates via Paul Walmsley <paul@pwsan.com>:

Fixes and IP block support for the TI AM33xx family of SoCs.  These
are prerequisites for power management and some PWM driver changes.

Basic test logs are available from:

   http://www.pwsan.com/omap/testlogs/am33xx_fixes_a_3.9/20130208084835/

although it must be noted that I am unable to test these patches on
AM33xx due to an unknown problem with v3.8-rc kernels:
