From 2c609c6b42c911df772d97c4ddf10d9374607e0c Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Thu, 13 Jul 2023 01:13:42 +0100 Subject: [PATCH] ASoC: wm8900: 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 wm8900 driver to use the more modern data structure.
