As the endpoint is unregistered there might still be work pending to
handle incoming messages, which will result in a use after free
scenario. The plan is to remove the rx_worker, but until then (and for
stable@) ensure that the work is stopped before the node is freed.

This snapshot is taken as of msm-4.19 'commit <d2f41beab007i>
("Merge "msm: npu: Add bandwidth monitor support"")'.
This change brings the rpmsg and rpmsg glink drivers up to date with
the fixes from msm-4.19. In addition, change the copyrights to SPDX format.
Also, irq_set_affinity and sched_setaffinity can not be used when compiling
a driver as a module. Hence, moving to module-friendly APIs.

A new application level feature has NAT running out of SRAM, DDR, or
both. The addtion of just this feature's header to the kernel will
allow it to be propagated to older kernels, such that they can be
compatible (in terms of structure size) with the new application level
feature.

To debug issues when TCS is busy, report interrupt status as well. If
the interrupt line is pending at GIC, then Linux was too busy to process
the interrupt and if not pending then AOSS was too busy to handle the
request.

During flush of current cached data, Sleep and Wake TCSes have
previously programmed data present. Due to this incorrect data
is sent.
Fix this by cleaning TCSes and freshly program current cached
sleep and wake data.

The arm_smmu_power_off_atomic() function derives the pointer to
the SMMU device by incorrectly assuming that all devices in the
power resources structures store that pointer as part of their
driver data.
While this is true for devices that represent an SMMU, this is
not the case for the devices that represent the TBUs, as they
store the TBU structures instead of a pointer to the SMMU device.
Thus, require the SMMU device as a parameter to the
arm_smmu_power_off[_atomic] functions so that it can be used
correctly.

Commit d698a38814 ("of: reserved-memory: ignore disabled memory-region
nodes") added an early return in of_reserved_mem_device_init_by_idx(), but
didn't call of_node_put() on a device_node whose ref-count was incremented
in the call to of_parse_phandle() preceding the early exit.
