regmap: Return a sensible error code if we fail to read the cache

2011-10-10T09:24:03+00:00

If a register isn't cached then let callers know that so they can fall
back or error handle appropriately.

regmap: Add the indexed cache support

2011-09-19T18:06:32+00:00

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.
