When a client request to disable MHI low power mode, it's
important MHI host only return after exiting MHI low power modes.
Otherwise, clients may get un-clocked register access when
accessing physical link. By checking host state, we're guaranteed
to return only after exiting low power states.

for suspend. Otherwise, MHI host driver prevent system suspend
from happening.

[ Upstream commit 1898eb61fbc9703efee886d3abec27a388cf28c3 ]
The ARM CCN PMU driver uses dev_warn() to complain about parameters in
the user-provided perf_event_attr. This means that under normal
operation (e.g. a single invocation of the perf tool), a number of
messages warnings may be logged to dmesg.
Tools may issue multiple syscalls to probe for feature support, and
multiple applications (from multiple users) can attempt to open events
simultaneously, so this is not very helpful, even if a user happens to
have access to dmesg. Worse, this can push important information out of
the dmesg ring buffer, and can significantly slow down syscall fuzzers,
vastly increasing the time it takes to find critical bugs.
Demote the dev_warn() instances to dev_dbg(), as is the case for all
other PMU drivers under drivers/perf/. Users who wish to debug PMU event
initialisation can enable dynamic debug to receive these messages.

exit low power mode even though there is no work to be done. For
downlink channels, assert wake only if MHI is in a low power mode
to avoid unnecessary wake ups.
