This patch series introduces the new caching API. The idea behind this
caching interface is that we can provide different means of organizing
and accessing the register cache. This is useful for large and sparse
register maps, where one can use some kind of compression algorithm to
reduce the memory footprint. The caching API is designed in such way to
eliminate the need for modifying any existing drivers.
Things that still need to be done.
- Memory usage statistics, to make it easier to select the proper caching
- Support for bulk reads/writes.

ASoC: soc-cache: Add support for flat register caching
ASoC: soc-cache: Add support for LZO register caching
ASoC: soc-cache: Add support for rbtree based register caching
