From dc1c6cf226dc99161a477e8b4488dfe97e0fa928 Mon Sep 17 00:00:00 2001 From: Adam Ford Date: Tue, 28 Nov 2023 15:18:31 -0600 Subject: [PATCH] arm64: dts: imx8mn: Enable Overdrive mode The i.MX8M Nano supports and overdrive mode if the SoC is given the proper voltage. Add imx8mn-overdrive.dtsi file which can be included by boards who support the voltage necessary to handle the faster clocks. This increases the GPU clocks from 400MHz to 600MHz.
