Error handling in time synchronization function is not
appropriate as an error in disabling link level low power modes
could cause a spin lock to be unlocked without being locked.

In order to ensure that a DRV resume follows immediately after
a client calls device wake assert or deassert, MHI core driver
must unconditionally increment the PM runtime usage count and
post a wake source before waiting for the state change.

An incorrect failure check needs to be fixed in the bandwidth
scaling initialization function as the absence of the supported
event ring support does not get factored in.

While writing any sequence or session identifiers, it is
possible that the host could write a zero value, whereas only
non-zero values are supported writes to those registers. Ensure
that host does not write a non-zero value for those cases.

Execution environment and power off changes can be serialized
to avoid changing these important controller variables from
multiple places and serialize handling of all state transitions.

Remove the unused timesync MHI device as we use the controller
device for timesync related activity instead.

Instead of sending a completion from the IRQ thread to notify a
worker thread to update the FIFO samples, update the samples in
the IRQ thread directly. This should help achieve lower latency
which is good for FIFO playing.
Meanwhile, following changes are made for FIFO playing:
1) Defer stopping command into erase() function if it's coming
before all FIFO samples are played. This gives the hardware
a little more time to play before stopping.
2) Restore FIFO play rate to T_LRA after playing is done according
to hardware recommendation.

The last entry of the a660_protected_regs array must be an empty
entry. The empty entry serves as a terminating placeholder value
indicating the end of the array.

A target may contain multiple defconfigs, but only one device-tree
configuration. Such a target may have device-drivers that are
only enabled in a particular defconfig, while disabled in the
others. For the kernel that boots up with disabled configuration,
since the device-tree node exists, the of_devlink logic expects
the driver to be probed, which is not possible. As a result, the
sync-state remains incomplete.
Hence, add support for a proxy consumer driver that shows a
proxy-presence of the main driver to satisfy the sync-state.

If we query the OPP table when it doesn't exist we get an error. If
we populate it again with the same operating points we get an error.
So just skip the table create if it already exists and go with
whatever we have.
