Texas Instruments' Keystone generation System on Chips (SoC) starting with 66AK2G02[1], 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. This series adds the base support for device control using generic power domain framework over the TI System Control Interface (TI-SCI) protocol[2][3]. Overall architecture is very similar to SCPI[4] as follows: +----------------+ +---------+ +------------+ | TI SCI GENPD(*)| |TISCI Clk| |TISCI reset | +------+---------+ +--+------+ +------+-----+ | | | | +----v--------------+ | +----------> TISCI Protocol <--+ +----+--------------+ | +---v-----------+ | MAILBOX FWK | +---+-----------+ | +---v-----------+ | TI MSGMGR |-> TISCI hardware block +---------------+ (*) This series.
