Merge tag 'omap-for-v3.8-rc4/fixes-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into fixes
From Tony Lindgren:
Minimal omap fixes for the -rc series:
- A build fix for recently merged omap DRM changes
- Regression fixes from the common clock framework conversion
for omap4 audio and omap2 reboot
- Regression fix for pandaboard WLAN control UART muxing caused by
u-boot only muxing essential pins nowadays
- Timer iteration fix for CONFIG_OF_DYNAMIC
- A section mismatch fix for ocp2scp init
