This patch from jbarnes and myself adds FIFO watermark control to the driver. This is needed for both power saving features on new platforms with the so-called "big FIFO" and for controlling FIFO allocation between pipes in multi-head configurations. It's also necessary infrastructure to support things like framebuffer compression and configuration supportability checks (i.e. checking a configuration against available bandwidth).
