Subject: [PATCH v3] arm64: dts: imx8mm: Add NOC node
Date: Thu,  4 Nov 2021 09:56:17 +0100	[thread overview]
Message-ID: <20211104085620.6048-1-tomm.merciai@gmail.com> (raw)

Add support for dynamic frequency scaling of the main NOC configuration
on imx8mm.

References:
 - i.MX 8M Mini Applications Processor RM, Rev. 3, 11/2020
 - f18e6d573b80 arm64: dts: imx8mq: Add NOC node
 - 912b9dacf3f0 arm64: dts: imx8mq: increase NOC clock to 800 MHz

Changes since v1:
 - Fix noc_opp_table frequencies taking NXP bsp as reference
 - Add reference link to nxp imx8mm dtsi on commit body

 Changes since v2:
 - Add missing signed-off line
