From 5410aa3aa7f7dfcbdfcf94034595765d7e69ead3 Mon Sep 17 00:00:00 2001 From: Bo Liu Date: Wed, 23 Apr 2025 21:08:55 -0400 Subject: [PATCH] regulator: pf9453: 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.
