Mark Brown	6e6ace00a0	regmap: Return a sensible error code if we fail to read the cache ... If a register isn't cached then let callers know that so they can fall back or error handle appropriately.

Dimitris Papastamos	195af65ca9	regmap: Add the indexed cache support ... This is the simplest form of a cache available in regcache. Any registers whose default value is 0 are ignored. If any of those registers are modified in the future, they will be placed in the cache on demand. The cache layout is essentially using the provided register defaults by the regcache core directly and does not re-map it to another representation.
