From bc3552d675537be111148d9614f4f02f31e30de3 Mon Sep 17 00:00:00 2001 From: Garrett Giordano Date: Tue, 1 Oct 2024 00:19:15 -0700 Subject: [PATCH] arm64: dts: ti: am62-phycore-som: Increase cpu frequency to 1.4 GHz The am625 is capable of running at 1.4 GHz when VDD_CORE is increased from 0.75V to 0.85V. Here we add a 1.4 GHz node to the a53_opp_table and increase the VDD_CORE voltage accordingly.
