Subject: [PATCH] gpio: fx6408: Convert to use maple tree register cache
Date: Fri, 29 Sep 2023 16:11:24 +0200 [thread overview]
Message-ID: <20230929-gpio-fx16408-v1-1-7fdd3218f7d6@kernel.org> (raw)
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.
