From 4f69e29ace9dce5f8226bfc99b77b8497d3d3d79 Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Sat, 10 Jun 2023 15:27:17 +0100 Subject: [PATCH] ASoC: rt1308: Use maple tree register cache The rt1308 can only support single register read and write operations so does not benefit from block writes. This means it gets no benefit from using the rbtree register cache over the maple tree register cache so convert it to use maple trees instead, it is more modern.
