From 80b06c5cae5487f590988fd296be36ecd97ede2a Mon Sep 17 00:00:00 2001 From: Anson Huang Date: Mon, 24 Feb 2020 10:07:40 +0800 Subject: [PATCH] arm64: dts: imx8mn: Adjust 1.2GHz OPP voltage to OD mode According to latest datasheet Rev.0, 10/2019, there is restriction as below: "If VDD_SOC/GPU/DDR = 0.95V, then VDD_ARM must be >= 0.95V." As by default SoC is running at OD mode(VDD_SOC = 0.95V), so VDD_ARM 1.2GHz OPP's voltage should be increased to 0.95V.
