[PATCH v1 13/13] regulator: rpi-panel-attiny: convert to use maple tree register cache

From: Bo Liu
Date: Wed Mar 20 2024 - 05:00:52 EST


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.
