Subject: [PATCH 4/4] clk: versaclock7: Convert to use maple tree register cache
Date: Fri, 29 Sep 2023 16:26:08 +0200	[thread overview]
Message-ID: <20230929-clk-maple-versaclk-v1-4-24dd5b3d8689@kernel.org> (raw)
In-Reply-To: <20230929-clk-maple-versaclk-v1-0-24dd5b3d8689@kernel.org>

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.
