Some displays may support Low Power modes, however, these modes may require special handling as they would usually require lower OPR content on framebuffers.

I'm not familiar with OPR. Can you explain what it is and what it means for user-space?

Also since this is new uapi, I guess best explanation would include the userspace code that makes sensible use of this. -Daniel
