Quoting Sibi Sankar (2021-08-18 20:02:07)
> The power domains exposed by the AOSS QMP driver control the load state
> resources linked to modem, adsp, cdsp remoteprocs. These are used to
> notify the Always on Subsystem (AOSS) that a particular co-processor is
> up/down. AOSS uses this information to wait for the co-processors to
> suspend before starting its sleep sequence.
>
> These co-processors enter low-power modes independent to that of the
> application processor and the load state resources linked to them are
> expected to remain unaltered across system suspend/resume cycles. To
> achieve this behavior lets stop using the power-domains exposed by the
> AOSS QMP node and replace them with generic qmp_send interface instead.
