2012-09-11video: tegra: host: add idle time estimate in 3dfsIlan Aelion
When a throughput hint is available, still keep track of the idle time percentage and use both in gpu scaling. Also modifying fallback scaling code to use same idle estimate used when a throughput hint is available. Dropping different time frames for scaling up and down.

As WAR, limit 3d clock frequency and emc clock frequency when camera is on and chip is AP37. 3d clock is set to 361MHz and 437MHz is requested for emc clock with this change. This change allows 3d to request 1.1V in Core instead of 1.3V in AP37.

2012-08-22video: tegra: host: Fix freeing a ERR_PTR valueTuomas Tynkkynen
nvhost_3dctx_alloc_common correctly checks the return value of an allocator function, and attempts to perform cleanup. However, this particular allocation API returns ERR_PTR values in case of failure, which then gets passed to the deallocation function, causing a crash. Also, the return value of that allocator API is checked with IS_ERR in some places, and with IS_ERR_OR_NULL in others. For consistency and avoiding surprises if the allocation implementation changes, use IS_ERR_OR_NULL in all places.
