2010-10-15[ARM/tegra] nvhost: Tuned ACM timeout.Alex Frid
Drastic reduction of ACM timeout to 2ms (from 1sec) resulted in power increase for NV omxplayer video-playback (bug 738557). The reason is that short-term scheduling does not provide enough idle time for LP2 state (CPU powered down). On the other hand, 1 sec timeout prevented core voltage scaling during Android music audio-playback (bug 735111). Hence, tuned ACM timeout to 25ms.

Sometimes, when uart ask for the dma for get the number of bytes transferred by dma, the dma does not return the actual number of bytes transffred, it returns the less number of byes (less by burst size) and so uart driver client gets the data loss in communication. So to avoid the race condition, the driver stops the incoming data by making RTS line to inactive and wait for some time to complete the dma burst and then ask dma to get number of bytes transffred by dma from fifo to memory.
