Some platforms have the capability to configure the performance state of their Power Domains. The performance levels are represented by positive integer values, a lower value represents lower performance state.
The power-domains until now were only concentrating on the idle state management of the device and this needs to change in order to reuse the infrastructure of power domains for active state management.
This patch adds binding to describe the performance states of a power domain.
The bindings would also need to take into account the fact that a device could (and is quite often the case with qcom platforms) have 2 separate powerdomains, one for idle state management and another to manage active states. I guess the below bindings assume that there's just one.
I have answered a similar question here..
