Don't believe WoV for WPT has been added for SST linux so
.ignore_suspend=1 achieves nothing. The offload part is probably just
limited to bigger buffer size compared to system pin than anything else.
So, nothing prevents from removing .ignore_suspend for SST solutions
until WoV is verified. Don't know about SOF side.
Pierre, what's your take on this?
I think on Baytrail and Broadwell we will most likely never enable
hotwording on the Intel DSP, and S0i1-Playback isn't planned either.
However hotwording is enabled on the RT5677 and there may be clocking
dependencies so that the RT5677 remains operational - at least the mclk
needs to be on, so the bdw-rt5677 case probably needs more work.
While I am at it, I think the notion of .ignore_suspend has an
assumption baked in. It will work if the only suspend mode is S0i1. If
the platform can choose between S0i1 and S3, then we would still want to
suspend all paths in S3, which currently isn't really possible.
