Adding AES suspend/resume functionality for LP0. Dedicated Key information is stored in the SDRAM using RFC-3394 key wraping algorithm. Dedicated slot information is restored back in the H/W during resume from LP0 by unwraping the key from SDRAM using RFC-3394 key unwraping. AES clocks are turned on only during the AES operations and are turned off after completion of the operations.

2010-06-23[ARM/tegra] power: tuned cpu idle loop.Alex Frid
- Updated cpuidle driver parameters: Determined LP2 state target_residency as a break even time balancing the power cost of LP2 entry/exit (estimated via LP2 latency), and LP2_vs_LP3 power saving - this approach is consistent with governor interpretation of residency. As a result the latency_to_residency factor reduced from 2.0 to 0.3. Included exit latency into idle time returned to governor to avoid double subtraction (by platform code and governor code) - otherwise under-reporting of LP2 time would skew downward governor correction algorithm. Replaced hard coded power good time with platform data. - Updated DVFS parameters Set CPU minimum frequency to 216MHz - additional dynamic power will be compensated by savings due to increased LP2 residency (216MHz is provided by low power PLL, and still allows CPU to run at lowest possible voltage). Changed maximum CPU/EMC frequency ratio to match new low corner settings.

2010-06-22[tegra ALSA]: Avoid race condition in state change.Manjula Gupta
As Play/Record and trigger thread both are modifying the prtd->state the current state of the thread, if START->STOP->START is called fast enough play/record might set the state to NVALSA_INVALID_STATE and doesn't execute STOP/START triggered by application at all. Play/Record thread should not modify the prtd->state, use the local variable 'state' to keep track of the current state of the play/record thread and to avoid execution of START/STOP multiple times. Here we are respecting only the last triggered state after processing of the current state, for example if application calls START->STOP->START->STOP fast enough play/record thread might execute only the first START and last STOP.
