From ed9fdff5ad8bb2b3dc8d86c788e763cbecddda13 Mon Sep 17 00:00:00 2001 From: Bo Liu Date: Tue, 6 Feb 2024 02:12:57 -0500 Subject: [PATCH] mfd: ac100: 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.
