Subject: [PATCH] arm64: dts: freescale: imx8mq: Disable noc dts node
Date: Thu, 11 Nov 2021 13:16:09 +0200	[thread overview]
Message-ID: <1636629369-23988-1-git-send-email-abel.vesa@nxp.com> (raw)

Adding interconnect properties to the consumer nodes creates
a dependency on noc device. The imx-bus devfreq driver is not usable
without the full interconnect support. The interconnect is not yet
working on i.MX platforms. The devlink created on device_add makes
the lcdif and other nodes that have the interconnect properties
wait for the noc (imx-bus driver) to probe first.

To make sure the interconnect consumers (nodes that have interconnect
properties already added) will still probe, lets disable the noc node
for now. Once the interconnect on i.MX platforms is fully functional,
the status of the noc node can be changed.
