Subject[PATCH v1 01/13] regulator: da9121: convert to use maple tree register cache
Date
The maple tree register cache is based on a much more modern data structure
than the rbtree cache and makes optimisation choices which are probably
more appropriate for modern systems than those made by the rbtree cache.
