[Alison Wang] We will not have bandwidth and develop the DRM driver in the near future. On the other hand, this IP is not integrated into other high-end SOC. So this fb driver will be used for some kind of long time for current SoC. We can try to remove the fb driver when we developed the DRM driver for other SoC.

Jean-Christophe, Do you have any comments? Thanks.
