Subject: ENGR00176571 MX6DL: Added support for 1.2GHz ARM Frequency
X-Git-Tag: v3.0.35-fsl~1353
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=d36ed3e5a67538831fb57dfce26f6c04f45a4c76;p=karo-tx-linux.git

ENGR00176571 MX6DL: Added support for 1.2GHz ARM Frequency

Added the new 1.2GHz working point.Currently 'arm_freq=1200"
should be added to commandline for the core to run at 1.2GHz
