This patch set implements fifomerge and a naive version for fifo threshold calculation when fifomerge is in use. The strategy is simple: keep the low threshold the same for both fifomerge and non-fifomerge cases, but calculate the high threshold using the combined fifo size when fifomerge is in use.
This should give some power savings, as the usable fifo size is much larger when only one overlay is in use. It probably won't help fifo underflow cases, as the low threshold is kept the same. Tested on OMAP4 Blaze (DSI cmd mode) and OMAP3 Overo (DPI).
