Add a function to query the glink core layer on whether a packet has
caused a wakeup. This function also takes a parameter to specify if the
wakeup state should be reset after reading the variable.
Add print to log the wakeup packet for glink interrupts. Some channels
such as IPCRTR will already reset the wakeup info state and print their
own messages. This print is meant to be a default print for all other
channels.

Glink irq should be wakeup capable, to achieve this irq is marked
with enable_irq_wake().
There are some use cases where glink communication is required in system
suspend path and glink interrupt handler needs to be run immediately.
But wakeup cpabale interrupts even if received during suspend will not
run immediately, this will be marked pending and run when system resumes
from suspend. In such scenario there can be a potential deadock in suspend
path due to any irq thread which is waiting for glink interrupt completion
while glink interrupt cannot be handled immediately.
One such use case is usb plugin interrupt received during suspend, which
calls regulator api to communicate with rpm over glink and waits for rpm
ack. RPM ack cannot be processed because glink interrupt received from rpm
goes in pending state. Suspend path is blocked because regulator irq thread
is still waiting.
So there is requirement to run glink interrupt handler in suspend path at
the same time making it wakeup capable. IRQ frameworks forbids usage of
both IRQF_NO_SUSPEND and enable_irq_wake() together. This patch adds
IRQF_NO_SUSPEND and pm_system_wakeup() for glink irq to implement this
requirement.

Glink pipe indices are reset by apps in the remoteproc
subdev stop path. There is a chance that the remote that
is being shutdown is in the middle of reading from the
pipe. This causes the remote that is shutting down
gracefully to crash as index 0 is invalid.
Remove the fifo reset from the remoteproc subdev stop
path. Register a function pointer with remoteproc for the
subdev to be called during prepare stage of ssr. Split
the glink probe to have pipes initialization, rx thread
creation and setting up glink structures happen in prepare
stage and version negotiation and char device creation in
prepare stage.
Given that the pipes get re-initialized during prepare
stage, the fifo indices will be intact until after the
remote has been shutdown completely and reset before the
remote is up again.
Spliting glink probe to prepare (in BEFORE_POWERUP) and
start (in AFTER_POWERUP) stage in spss results in glink
link up callback arriving earlier on spss when one of the
destination services is not yet created. This results in
spss not finishing the boot flow after ssr.
Adding glink fifo reset to be called as part of BEFORE_SHUTDOWN
if the underlying driver has callbacks setup for it as is the
case in spss rpmsg driver.

Some remote procs do not initialize the pipe when they are started
and assume the data in the pipe descriptors is valid. Add an optional
handler to clear the pipe descriptors and call this during removal
of the glink device to ensure a clean restart of glink.

Currently when a remote subsystem goes down, remove_subdev will be
called from rproc for removing that subsystem from the list, but
this could be too late. Register for early SSR notifications for
getting notified about before shutdown, so that the glink_send calls
to the dead processor will not get blocked.

Wait for actul intent allocation to complete before again requesting
for same intent. Currently on getting intent request ack glink looks
for allocated intent and if it is not found it again requests.
In some cases remote host may delay allocation of intents but acknowledge
it immediately, in such cases glink will keep on requesting same intent
repeatedly. Now added code to wait for actual intent allocation to complete
and timeout if it is not allocated within 10 sec.

variable to a waitqueue to check both intent request completion and

Channel release function is not making intent wait condition true
before calling wake_up, due to this thread waiting on intent is
stuck and does not wake up until timeout happens. By this time
channel context is freed and this casues finish wait to fail due
to access of wait queue in freed channel context.
Mark intent request complete before calling wake_up.

Receive callback can be registered even before rpmsg driver probe is
complete. Assuming callback register as channel ready and allowing
remote host to send data is incorrect. In such case for any rx packet
callback may return prematurely thereby dropping the rx packet.
Adding a flag to store channel state when it is ready. Check this flag
before allocating rx intent and allowing data communication to proceed.
It will ensure that client driver is able to receive data correctly,
without any rx packet getting dropped.

In high traffic scenarios a remote may request extra intents to send
data faster. If the work thread that handles these intent requests is
starved of cpu time, then these requests can build up. Some remote
procs may not be able to handle this burst of built up intent requests.
In order to prevent intent build up, deny intent requests that can be
fulfilled by default intents that are reusable.
