From 7f70d4590d949e1488f8ff7ebc35ee238a1e0661 Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Sun, 1 Oct 2023 00:44:22 +0100 Subject: [PATCH] mfd: rk8xx: 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.
