Common Display Framework
In supporting not only panel drivers, but also transmitter and bridge drivers from multiple display control frameworks like DRM and FBDEV, it became clear that what was needed was a common display framework rather than board-specific callback mechanisms. More detailed information on the discussion and arguments in favor can be found here:

[Vikas: 12-12-12] Undestood the CDF RFC v2 patchset.
[Vikas: 12-12-12] Have some confusion regarding the MIPI DSI support in th CDF, need to get clarity from Laurent.
[Vikas: 12-12-12] Understood the Exynos 5250 MIPI DSI based display driver.
[Vikas: 12-12-12] Sent a mail Laurent regarding the MIPI DSI support in the CDF, yet to get the feedback from him.
[Vikas: 12-12-12] Need to get answer for following questions
• How to accommodate the non MIPI based display panels (eDP ) in CDF?
• Samsung Exynos supports MIPI DSI based display panels, how to accommodate such thing in CDF? I mean how do I register my MIPI DSI driver?
• When went through the patches I couldn’t find the caller of mipi_dbi_
