OMAPDSS: DISPC: Add naive threshold calc for fifomerge
Take fifo merge into use by implementing a rather naive fifo merge threshold calculation: keep the low threshold always the same, but increase the high threshold when fifo merge is used. This should greatly increase the time between pixel data fetches from SDRAM, as the usable fifo size is much larger. However, it probably won't help for fifo underflows, as the low threshols is kept the same. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
