Subject: [PATCH 7/9] soc: sunxi: sram: Save a pointer to the OF match data
Date: Sun, 31 Jul 2022 22:05:07 -0500 [thread overview]
Message-ID: <20220801030509.21966-8-samuel@sholland.org> (raw)
In-Reply-To: <20220801030509.21966-1-samuel@sholland.org>
It is inefficient to match the compatible string every time the regmap
is accessed.
