*CAVS DSP Wall Clock Timer on Intel SoC*

Type: ``bool``

Help
====

The DSP wall clock timer is a timer driven directly by
external oscillator and is external to the CPU core(s).
It is not as fast as the internal core clock, but provides
a common and synchronized counter for all CPU cores (which
is useful for SMP).
