Merge branch 'for-4.10-ti-sci-base' of https://github.com/t-kristo/linux-pm into next/drivers
Merge "ARM: keystone: add TI SCI protocol support for v4.10" from
Tero Kristo:
[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.]
