Merge tag 'omapdss-for-3.8' of git://gitorious.org/linux-omap-dss2/linux into for-linus
OMAPDSS changes for 3.8, including:
- use dynanic debug prints
- OMAP platform dependency removals
- Creation of compat-layer, helping us to improve omapdrm
- Misc cleanups, aiming to make omadss more in line with the upcoming common
display framework
