From a50afa310d6a4c765a1787742b206eb149bb1d12 Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Tue, 12 Sep 2023 12:36:46 +0100 Subject: [PATCH] mfd: wcd934x: Update 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. In v6.5 it has also acquired the ability to generate multi-register writes in sync operations, bringing performance up to parity with the rbtree cache there. Update the wcd934x to use the more modern data structure.
