From 7eab62ecbcbb732ee6a09878e4c05fd4e7a0c6b1 Mon Sep 17 00:00:00 2001 From: chuguangqing Date: Wed, 11 Jun 2025 16:58:36 +0800 Subject: [PATCH] iio: light: isl29028: 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.
