[RFC 17/19] arm64: dts: imx8mq: Add interconnect properties to icc consumer nodes
From: Abel Vesa
Date: Fri Feb 19 2021 - 11:06:59 EST
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.
