Subject: [PATCH V3 0/5] firmware: Add support for TI System Control Interface (TI-SCI) protocol driver
Date: Tue, 6 Sep 2016 14:01:22 -0500 [thread overview]
Message-ID: <20160906190127.23522-1-nm@ti.com> (raw)
Hi,
Version 3 of the series with change in the way we describe the children
nodes (no change to drivers required - only the dts description changes).
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 TI System Control Interface
(TI-SCI) protocol[2]. The protocol is built on top of Texas
Instrument's Message Manager communication mechanism[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.
V3 of the series is based off v4.8-rc1 and is also available here:
https://github.com/nmenon/linux-2.6-playground/commits/upstream/v4.9/tisci-base-v3
integration of v3 along with https://lkml.org/lkml/2016/8/19/790 and
https://lkml.org/lkml/2016/8/19/811 is available here:
https://github.com/nmenon/linux-2.6-playground/commits/upstream/v4.9/tisci-integ-v3
Test of complete integrated solution: http://pastebin.ubuntu.com/23142652/
Changes since v2:
- Child nodes are now children of the TISCI node
- related driver updates

V1: https://lkml.org/lkml/2016/8/19/768
