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..
