Subject: [PATCH 2/4] iio: accel: bma400: convert to use maple tree register cache
Date: Wed, 12 Feb 2025 02:52:21 -0500 [thread overview]
Message-ID: <20250212075223.4164-3-liubo03@inspur.com> (raw)
In-Reply-To: <20250212075223.4164-1-liubo03@inspur.com>
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.
