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
modeling them as power-domains and replace them with generic qmp_send
interface instead.

The load state resources are expected to follow the life cycle of the
remote processor it tracks. However, modeling load state resources as
power-domains result in them getting turned off during system suspend
and thereby falling out of sync with the remote processors that are still
on. Fix this by replacing load state resource control through the generic
qmp message send interface instead.

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.

state resources on SM8350 SoCs and drop deprecated power-domains exposed
by AOSS QMP node.

Is it possible to keep this code around for a cycle so that there isn't
the chance that someone is using the deprecated DT bindings with a new
kernel? I worry that ripping the code out will cause them angst.
Certainly we have to keep the code in place until DT is updated, so this
patch should come last?

deprecated bindings with a newer kernel
shouldn't cause any problems since it is
the driver changes that make AOSS PD
mandatory or not. So the newer kernel will
just use qmp_send and leave the PD unused.

sure I don't mind, as long as it simplifies
the merge process.

That's obvious from the diff. The commit msg should tell us why.
