You have to add more detailed what to do on this driver.
Also, please add the full alphabet for CCI.

Usually, dt-binding document only specifies h/w information
and how to bind device. 'devfreq' is the word of linux-side.
It means that 'devfreq' cannot indicate the any h/w device.
You should use the h/w device information and word of CCI for writing
the dt-binding document without linux-side word like devfreq.
For example,
- cci devfreq -> frequency scaling of CCI

This document is missing the 'regulator' property. Please add it
