From d4ac6028b991b866803ffa36a1039d5573a4f52a Mon Sep 17 00:00:00 2001 From: Peng Fan Date: Thu, 7 Jul 2022 07:47:57 +0800 Subject: [PATCH] arm64: dts: imx8mp: add NoC node Add i.MX8MP NoC node to make the interconnect i.MX8MP driver could work. Currently dynamic frequency scaling of the i.MX8MP NoC has not been supported, only NoC initial settings are configured by interconnect driver.
