Subject: [PATCH 0/3] ARM: K2G: Add support for TI-SCI Generic PM Domains
Date: Fri, 19 Aug 2016 18:56:50 -0500 [thread overview]
Message-ID: <20160819235653.26355-1-nm@ti.com> (raw)
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.
Baseline: v4.8-rc1 + [3] (the dependency is due to MAINTAINERS update)
Bootlog: http://pastebin.ubuntu.com/23071846/ (with the addition of couple of mach patches + dts)
Integrated series is available:
