From 28787bf47b11b08290918dcf91b08764cb5fe122 Mon Sep 17 00:00:00 2001 From: Quentin Schulz Date: Mon, 20 Mar 2017 12:25:51 +0100 Subject: ARM: sun8i: a33: remove highest OPP to fix CPU crashes The highest supported frequency (1.2GHz) requires to "overvolt" the CPU. However, some boards still do not have the cpu-supply DT property in the cpu DT node which means that the CPU will always run with the same input voltage but try to run at 1.2GHz frequency. This is the source of (experienced) CPU crashes. Remove the OPP which requires overvolting the CPU until all boards have a cpu-supply property.
