+ The kernel has 2 drivers for the Low Power Engine audio-block on
+ Bay- and Cherry-Trail SoCs. The old SST driver and the new SOF
+ driver. If both drivers are enabled then the kernel will default
+ to using the old SST driver, unless told otherwise through the
+ snd_intel_dspcfg.dsp_driver module-parameter.
+
+ Set this option to Y to make the kernel default to the new SOF
+ driver instead.
