The last one is clearly listed in the regmap list.
You probably want to reverse-engineer what causes these accesses. I see this suspicious kcontrol definition that might be related:
SOC_SINGLE("Left I Tag Select", 0x3004, 4, 7, 0),
Looks like a case for putting the CODEC in cache only mode...
Right, and I think we'd need to do this during the probe instead of the hardware initialization (which could happen at a later time).
I started a PR to try and improve regmap handling, see https://github.com/thesofproject/linux/pull/3941
I was trying to solve the case where codecs become unattached, but apparently the problem is hardware-related. One of the suggested improvements was to move the cache_only part earlier to prevent such accesses. Unfortunately the work isn't complete so that PR is just a draft at the moment.
