From 66b1abc17c9d9e4af58098b9d6b8d7ade961e195 Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Wed, 12 Jul 2023 19:44:31 +0100 Subject: [PATCH] ASoC: sti-sas: 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 sti-sas driver to use the more modern data structure.
