2. The PRM asserts asynchronously all IVA2 power domain warm reset signals (and all other warm reset
signals).
3. The PRCM.
register is reset to its default value. As a result, the IVA2 power
domain warm reset signals stay asserted on release of the global warm source of reset.
4. DPLL2 is held under its reset configuration; the IVA2 power domain clocks are stopped.
5. The sys_nreswarm global warm source of reset is deasserted.
6. The PRCM.
status register is updated accordingly when the device reset manager
times out.
7. The MPU boots and the MPU software sequence, shown in
, from point 6, starts.

The assumptions are:
•
The MPU is running.
•
All sources of reset to the IVA2 are released.
•
The software ensures that the IVA2 power domain software sources of reset are not asserted while the
