Hello,

these patches implement support for setting the rate of the EMC clock based on
stats collected from the ACTMON, a piece of hw in the Tegra124 that counts
memory accesses (among others).

It depends on the following in-flight patches:

* MC driver: http://thread.gmane.org/gmane.linux.ports.tegra/19623
* EMC driver: http://thread.gmane.org/gmane.linux.ports.arm.kernel/365125
* CPUFreq driver: http://thread.gmane.org/gmane.linux.kernel/1812962

I have pushed a branch here for testing:

Regards,

Tomeu
