From 10cfb14d2a2b67751cef93a1c75d3797ec433c52 Mon Sep 17 00:00:00 2001 From: Bo Liu Date: Sat, 9 Mar 2024 02:17:57 -0500 Subject: [PATCH] usb: typec: stusb160x: 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.
