This driver supports communication with secure processor subsystem
over rpmsg and ungerlying glink transport layer.
The communication is based on using shared memory and interrupts.
This driver exposes interface to user space.
Migrate from using glink api to rpmsg api:
- removed not used glink functionality
- removed not used kernel api to spcom functionality
- implemented rpmsg driver registration for each new spcom channel
open/close/tx/rx/poll flows fixes:
- rpmsg_abort flag introduced to synchronize close() of a channel with
pending sending or receiving data from the channel
- tx implemented as rpmsg_trysend() every 10ms (timeout_msec total)
- poll imlemented link up/down events as first/last rpmsg device
probed/removed
- locking
ION api replaced by dma-buf:
ION api depricated.
This change implements following functionality:
Lock/unlock shared buffer by reference counting on underline dma-buf.
Translation user allocated shared buffer virtual address to
physical address (to enable SPU access to the buffer).

MHI Host Interface is a communication protocol to be used by the host
to control and communicate with modem over a high speed peripheral bus.
Enabling this stack will allow host to communicate with external devices
that support MHI protocol.

Commit d92bfe55f8cc4dc1 ("power: smb5: update IRQ configuration") adds
wakeup capabilities to several IRQs. Extend this to include
TYPEC_ATTACH_DETACH_IRQ as well. And while we're at it, associate
TYPEC_ATTACH_DETACH_IRQ with the right IRQ handler routine.

RCU's expedited grace periods can participate in out-of-memory deadlocks
due to all available system_wq kthreads being blocked and there not being
memory available to create more. This commit prevents such deadlocks
by allocating an RCU-specific workqueue_struct at early boot time, and
providing it with a rescuer to ensure forward progress. This uses the
shiny new init_rescuer() function provided by Tejun (but indirectly).
This commit also causes SRCU to use this new RCU-specific
workqueue_struct. Note that SRCU's use of workqueues never blocks them
waiting for readers, so this should be safe from a forward-progress
viewpoint. Note that this moves SRCU from system_power_efficient_wq
to a normal workqueue. In the unlikely event that this results in
measurable degradation, a separate power-efficient workqueue will be
creates for SRCU.

Driver needs to pass qdss data received from mdm qdss
bridge driver to host PC. This requires a software data
path using IN endpoint. Bridge driver needs to open
qdss_mdm channel and use exported write() API to pass
the qdss data received from mdm. Driver calls the notify
call back upon write completion.

Currently, if a subsystem does not send a response through QMI
confirming that it has properly gone through its shutdown
sequence within a certain time, it is assumed that something
went wrong, and the subsystem could not shutdown gracefully.
However, for some subsystems, part of their shutdown sequence
may involve disabling the QMI service prior to sending the
response, and continuing the rest of the shutdown sequence
without any problems. The real indicator of an issue is not
receiving either an SMP2P interrupt or an QMI indication that
the subsystem has shutdown. Allow for timeouts to be
an acceptable cause of a graceful shutdown sequence, and wait
for either an SMP2P interrupt or QMI indication that indicate
whether the device has shutdown or not.
