Subject: [PATCH V2 1/2] ARM: dts: imx6q: add 852MHz setpoint for CPU freq
Date: Wed, 12 Feb 2014 17:57:02 +0800	[thread overview]
Message-ID: <1392199023-29880-1-git-send-email-b20788@freescale.com> (raw)

According to datasheet, i.MX6Q has setpoint of 852MHz
which is exclusive with 996MHz, the fuse map of speed_grading
defines the max speed of ARM, here we add this 852MHz
setpoint opp info, kernel will check the speed_grading
fuse and remove all illegal setpoints.
