Subject: [PATCH 8/8] arm64: dts: imx8m: Add NOC nodes
Date: Thu, 26 Mar 2020 04:16:20 +0200 [thread overview]
Message-ID: <ae34326e03926a5ce2ec458d6acbc2953694cfd5.1585188175.git.leonard.crestez@nxp.com> (raw)
In-Reply-To: <cover.1585188174.git.leonard.crestez@nxp.com>
In-Reply-To: <cover.1585188174.git.leonard.crestez@nxp.com>
Add nodes for the main interconnect of the imx8m series chips.
These nodes are bound to by devfreq and interconnect drivers.
