Subject: [PATCH 1/2] arm: dts: imx6q: update cpufreq volt/freq table
Date: Fri, 5 Dec 2014 16:23:48 +0800	[thread overview]
Message-ID: <1417767829-11314-1-git-send-email-b20788@freescale.com> (raw)

According to latest i.MX6Q datasheet Rev. 3, 02/2014,
the latest cpufreq volt/freq table is as below:

LDO enabled/bypassed(min value):
996MHz: VDDARM: 1.225V, VDDSOC: 1.150V;
792MHz: VDDARM: 1.150V, VDDSOC: 1.150V;
396MHz: VDDARM: 0.925V, VDDSOC: 1.150V;

the 792MHz setpoint's VDDARM min voltage is updated
from 1.125V to 1.150V, adding 25mV to cover board IR
drop, 1.175V is the right voltage we should use.
