Subject: [PATCH 08/18] mfd: khadas-mcu: convert to use maple tree register cache
Date: Tue, 6 Feb 2024 02:13:04 -0500	[thread overview]
Message-ID: <20240206071314.8721-9-liubo03@inspur.com> (raw)
In-Reply-To: <20240206071314.8721-1-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.
