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

OMAP FB allocates the framebuffer memory using the OMAP VRAM allocator.

OMAP FB allocates the framebuffer memory using the standard dma allocator. You

can enable Contiguous Memory Allocator (CONFIG_CMA) to improve the dma

allocator, and if CMA is enabled, you use "cma=" kernel parameter to increase

the global memory area for CMA.



Using DSI DPLL to generate pixel clock it is possible produce the pixel clock

of 86.5MHz (max possible), and with that you get 1280x1024@57 output from DVI.

vram=<size>[,<physaddr>]
