From 36649db5b216a85cfd7937a289c4cdd0b4b69126 Mon Sep 17 00:00:00 2001 From: Bo Liu Date: Wed, 20 Mar 2024 04:57:31 -0400 Subject: [PATCH] regulator: max8973: convert to use maple tree register cache 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.
