From 43e568c4ae9a35e2458737c7d995b183e21b8a6f Mon Sep 17 00:00:00 2001 From: Nikita Kiryanov Date: Fri, 19 Feb 2016 19:19:49 +0200 Subject: arm: am437x: cm-t43: set MPU and CORE voltages on boot During boot, U-Boot raises the CPU frequency but the CORE and MPU regulators are not updated. This is not a problem in cold boot since the default values that the pmic outputs are correct, but if Linux were to switch the module to a low power OPP, the new voltage values will be retained after a reboot and the module will likely hang once U-Boot raises the CPU frequency back up. Set both CORE and MPU regulators to to 1.1V on boot.
