The Always On Subsystem (AOSS) Qualcomm Messaging Protocol (QMP) driver is used to communicate with the AOSS for certain side-channel requests, that are not available through the RPMh interface. The communication is a very simple synchronous mechanism of messages being written in message RAM and a doorbell in the AOSS is rung. As the AOSS has processed the message length is cleared and an interrupt is fired by the AOSS as acknowledgment. The driver exposes the QDSS clock as a clock and the low-power state associated with the remoteprocs in the system as a set of power-domains.
