OMAP4: DSS FIFO Threshold Optimization patch
DSS FIFO size need to be determined based on the GFX,Video pipeline usage and
parameters, instead of using static values, to meet performance and less system
cycles.
This patch addresses 2 issues:
- Optimial fifo thresholds for Gfx/video pipelines to aid longer MSTBY period for power
savings without compromising on performance (no underrun scenarios)
- If DSS operates heavy usecase with improper fifo thresholds, DSS MSTBY wont be asserted
resulting of break in DSS,CORE suspend transitions
This K3.0 patch is ported from below K35 patches
