You'd need to make regcache-flat keep track of which cache values are valid either during init (in which case it'd have to read every other register at that time) or at runtime (which would mean extra operations in a fast path). Flat really is special here, there's no reason to use it over a rbtree other than being very sensitive about performance. Please also be aware that if you CC me on an iio patch series there's a good chance I'll just delete it without reading it, for some reason I keep on getting copied on lots of them which have no relevance to me that I'm able to identify.
