From 21ff89b91bf871ad4512a8acfa414fd71bea4409 Mon Sep 17 00:00:00 2001 From: Bo Liu Date: Tue, 6 Feb 2024 02:13:08 -0500 Subject: [PATCH] mfd: rk8xx: 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.
