From baaa1b8e7d84d9b5399d8e75f6c9241465869c0e Mon Sep 17 00:00:00 2001 From: Bo Liu Date: Tue, 6 Feb 2024 02:13:05 -0500 Subject: [PATCH] mfd: lochnagar-i2c: 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.
