Subject: [RFC 16/19] arm64: dts: imx8mq: Add interconnect properties to icc consumer nodes
Date: Mon, 13 Sep 2021 20:38:11 +0300 [thread overview]
Message-ID: <1631554694-9599-17-git-send-email-abel.vesa@nxp.com> (raw)
In-Reply-To: <1631554694-9599-1-git-send-email-abel.vesa@nxp.com>
We add all the properties necessary to control the interconnect
based on the required rates all the way from consumers to the dram.
The fsl,icc-rate specifies the minimum required rate the consumer needs
in order to operate.
For now, only the fec, usdhc1 and usdhc2 are added as consumers.
