Subject: [PATCH] arm64: dts: imx8mq: increase NOC clock to 800 MHz
Date: Wed, 27 Nov 2019 12:05:09 +0100 [thread overview]
Message-ID: <20191127110509.29905-1-l.stach@pengutronix.de> (raw)
From: Philipp Zabel <p.zabel@pengutronix.de>
The NOC clock defaults to 400 MHz. Increase it to 800 MHz for improved
memory performance.
