Subject: [PATCH] mfd: twl6040: Use maple tree register cache
Date: Sat, 10 Jun 2023 15:05:21 +0100 [thread overview]
Message-ID: <20230609-mfd-twl6040-maple-v1-1-3493d051cd6f@kernel.org> (raw)
The twl6040 is only capable of performing single register read and write
operations which means it gains no advantage from using a rbtree register
cache, convert it to using the more modern maple tree register cache
instead. This should be more efficient.
