The DSPs IRQ should be a wake source as several of the possible
algorithms may run whilst the AP is asleepi and require to wake the AP
to push or pull more data, such as compressed playback.

CONFIG_HOTPLUG is going away as an option.  As result the __dev*

The info record at the start of the dsp firmware file has been
expanded to incorporate additional version information. We need
to check the version to make sure we understand the layout of
the information in the record. The srec2image tool is currently
used to create this record during creation of the .dfw file.

The WM0010 is a compact digital signal processor that has been
highly optimised for low-power audio applications.  Extensive memory
resources and core optimisation allow the device to manage all audio
processing algorithms efficiently and autonomously, while the host
processor sleeps or performs other tasks.
