From: Jeson Gao <[email protected]>
Reducing frequency to too low will affect the system performance, and
sometimes the temperature could not cool down to an ideal value as well
even if the frequency was reduced to the lowest.
This patch provides users a callback to set its own frequency limit to
prevent cpu frequence from being reduced too low. And also give an interface
to allow users to register specific cooling operations, such as unplug cores
or cpu isolation.
Any comments are very appreciated.
