2012-07-25ARM: tegra: cpuquiet: Notify the cpuquiet governor when the driver is busySai Charan Gurrappadi
Added generic busy/free notifiers that the driver can invoke to let the governor know that it cannot process further core online/offline requests (invoked in our case whenever we switch to the LP cluster).
