Sorry for the delay. I just saw this pull request in the backlog
and had to take a closer look first. I probably would have commented
on a few details in a proper review, but overall this seems harmless
enough, so I've merged it into next/drivers in the end.

There was no branch description in
 https://github.com/t-kristo/linux-pm.git for-4.10-ti-sci-base
and I ended up taking something from the wiki. This is now the
commit I ended up with:

    [description taken from http://processors.wiki.ti.com/index.php/TISCI
    
    Texas Instruments' Keystone generation System on Chips (SoC) starting
    with 66AK2G02, now include a dedicated SoC System Control entity called
    PMMC(Power Management Micro Controller) in line with ARM architecture
    recommendations. The function of this module is to integrate all system
    operations in a centralized location. Communication with the SoC System
    Control entity from various processing units like ARM/DSP occurs over
    Message Manager hardware block.
    
    ...
    
    Texas Instruments' System Control Interface defines the communication
    protocol between various processing entities to the System Control Entity
    on TI SoCs. This is a set of message formats and sequence of operations
    required to communicate and get system services processed from System
    Control entity in the SoC.]
