Thank you for finding that cherryview kernel issue. Unfortunately, their original patch is very limited as it's tied to an arbitrary BIOS date and doesn't work for my machine. Would it be possible to also include better quirk that went into 4.12? Please see v2 quirk in 194945 or https://github.com/torvalds/linux/commit/2a8209fa68236ad65363dba03db5dbced520268a
