[PATCH] cpufreq: dt-platdev: Add devices covered by ti-cpufreq to blacklist

From: Dave Gerlach
Date: Tue Sep 19 2017 - 10:58:15 EST

Commit edeec420de24 ("cpufreq: dt-platdev: Automatically create cpufreq
device with OPP v2") causes a cpufreq-dt platform device to be
automatically created for any platform with an OPP v2 node defined.
However, ti-cpufreq registers the cpufreq-dt platdev at the end of probe
in order to ensure the ti-cpufreq driver probes first and provides the
necessary opp-supported-hw for cpufreq-dt. With this new patch now a
dupluicate cpufreq-dt is created, which we do not want. To avoid this,
add the platforms handled by ti-cpufreq to the blacklist provided in the
aforementioned commit to allow ti-cpufreq to continue creating the
cpufreq-dt platdev.

This applies to am335x, am437x, dra7xx, and am57xx.
