** Description changed: + [SRU justification] + + [Impact] + System does not enter to lower power state when suspend, the QAIC card consumes excess power. + + [Fix] + Cherry pick "3301ef0 accel/qaic: Add support for PM callbacks" from linux-next and a few other commits recommended by Qualcomm + + [Test Case] + Suspend and resume the machine, check if the machine can resume correctly, check if devices are functional. Check power consumption during suspend that it's lower than before. + + [Where problems could occur] + Introduces new code path for power management, suspend/resume may break so thorough testing is required. + + --- + [Steps to reproduce] Install ubuntu 24.04 suspend the system - [Expected result] system will enter a low power state [Actual result] the QAIC card continues to draw 6 watts of power. [Failure rate] 100%
