Subject: [RFC 04/19] devfreq: imx8m-ddrc: Change governor to powersave
Date: Mon, 13 Sep 2021 20:37:59 +0300 [thread overview]
Message-ID: <1631554694-9599-5-git-send-email-abel.vesa@nxp.com> (raw)
In-Reply-To: <1631554694-9599-1-git-send-email-abel.vesa@nxp.com>
By switching to powersave governor, we allow the imx8m-ddrc to always
run at minimum rate needed by all the running masters.
