From c186e85c726b0d8a9d4a5d12d00bdefa2cdbd295 Mon Sep 17 00:00:00 2001 From: Francesco Dolcini Date: Tue, 13 Feb 2024 16:56:22 +0100 Subject: [PATCH] arm64: dts: ti: verdin-am62: Set VDD CORE minimum voltage to 0.75V Set VDD_CORE minimum voltage to 0.75V, TI AM62 can run at either 0.75V or 0.85V depending on the actual speed grade and on the maximum configured speed (1.4GHz frequency requires 0.85V). The actual value is programmed into the PMIC EEPROM during manufacturing (according to the SOC speed grade) and this ensure that both the voltage values are valid and therefore the OS will not overwrite the value programmed into the PMIC.
