After sending a sysmon shutdown request to the SSCTL service on the
subsystem, wait for the service to set a shutdown_ack smp2p bit in
addition to sending the indication message back.

Add support to make scm_calls to TZ to inform modem start
address and size so that TZ can unmap this range to avoid
speculative access.

It is useful to retrieve small memory areas from a device
when performing a subsystem restart. For example, shared
memory may contain logging information that can help
triage a problem. Implementations may choose to dump such
memory sections when the enable_mini_ramdumps flag is set.

Certain subsystems may require memory associated with
a subsystem to be freed after a memory dump has been
taken. Previously, this was expected to be done in the
shutdown callback. Add a new callback that implementations
can take advantage of to free memory when they see fit,
either in shutdown or in the new callback.

On newer targets having a common single binary, subsystem
clients will need the option to specify the firmware image
to use for booting up the subsystem. Provide a new API for
the same.
Clients will now be able to specify the firmware name to use
as one of the parameters to this API. Also, for clients which
trigger subsystem boot and shutdown via the open and close file
ops, a sysfs node "firmware_name" is exposed. By writing to this
node, the client can change the firmware used to boot dynamically.

Add a new system_debug subsystem property. This is set as
"reset" by default. When this parameter is listed as "set"
for a subsystem and a wdog bite happens, the SSR framework
goes ahead and triggers a kernel panic.
This feature is strictly intented only for debugging cases
where a system ramdump is more desirable than subsystem
ramdumps.

A feature in the modem requires that the modem be
restarted as part of normal operation rather than
as a response to a fatal error. In these instances,
it is preferred that ramdump collection be avoided.
If a certain GPIO is set, disable ramdump collection
during a subsystem restart sequence.

When the ref-count for a subsystem goes down to 0, i.e.
there are no current clients for it, the subsystem is
shutdown by calling the shutdown callbacks registered
by the subsystem driver.
Before doing so, send the sysmon shutdown command to
the subsystem so that it could take care of any cleanup
required at its end.

for storing the platform device id that sysmon is probed
with for that subsystem. This information is required to
remove having to statically store the names of subsystems
that have sysmon support.

for storing the instance id with which the subsystem driver
connects to the QMI Subsystem Control(SSCTL) service. This
service is hosted by a hardware subsystem with the APSS being
the client, to issue commands such as shutdown or to pass event
information.

Add sending the platform device pointer and the no_auth boolean
in the notif_data struct. It is left upto the drivers who have
registered for notifications about the individual subsystems to
use this information according to their need.
This change is required to enable drivers to authenticate and
bring subsystems out of reset instead of using the PIL ops.

Architectural changes in the ARM Linux kernel require moving
some MSM specific headers related to the peripheral image
loader and the subsystem restart drivers to include/soc/qcom.
subsystem_restart.h is used by external modules and thus
leave a proxy in include/soc/qcom for now. Once external modules
switch over to this new include path, the header in the
old location can be deleted.
