disabling the clock to avoid flooding of interrupts when
master is turned on for pending slave irq.

Soundwire slave interrupt is only edge type, so any pending slave
side interrupts could not cause a new slave interrupt, if
they are triggered before clearing of existing interrupts.
Recursively trigger slave irq until there are no pending slave
interrupts to handle this issue.

When temperature on a single wsa881x device is being read,
then soundwire master wakes up both wsa881x devices but
regcache_sync is happening only for one wsa881x device on
which the temperature is being read. This results in
audio playback mute after temperature read. Fix the

Add support for SND event framework for helping with
notifications among different audio modules/drivers.
The SND event framework functions with a master/client
mechanism, where each client and the master register
with the framework, and then notifies its own status
(UP/DOWN). Each master will share a list of clients it
is interested in, and once all the clients are registered
and notified UP, the framework's state will be UP. On the
other hand, as and when any one of the client, or the master
reports its state as DOWN while the framework is UP, the
framework state would be changed to DOWN, and all clients
and the master would be let know about the change.
