From cc42e969ebbbd8e9bb511b3880a8e046cf88710f Mon Sep 17 00:00:00 2001 From: chuguangqing Date: Wed, 11 Jun 2025 16:58:30 +0800 Subject: [PATCH] iio: dac: ad5380: 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.
