This needs to be root-caused. The register cache in regmap is for
using not for decoration.

What is the problems you are seeing?

If it is fundamentally so that regmap has limitations that is one thing,
but I want to rule out that we're just not using it wrong or that there
is a bug in it that we should fix.

Looping in Mark Brown the regmap maintainer.

Yours,
