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 V2: https://lkml.org/lkml/2016/8/30/273 V1: https://lkml.org/lkml/2016/8/19/768 Nishanth Menon (5): Documentation: Add support for TI System Control Interface (TI-SCI) protocol firmware: Add basic support for TI System Control Interface (TI-SCI) protocol firmware: ti_sci: Add support for Device control firmware: ti_sci: Add support for Clock control firmware: ti_sci: Add support for reboot core service .../devicetree/bindings/arm/keystone/ti,sci.txt | 81 + MAINTAINERS | 10 + drivers/firmware/Kconfig | 15 + drivers/firmware/Makefile | 1 + drivers/firmware/ti_sci.c | 1993 ++++++++++++++++++++ drivers/firmware/ti_sci.h | 492 +++++ include/linux/soc/ti/ti_sci_protocol.h | 249 +++ 7 files changed, 2841 insertions(+) create mode 100644 Documentation/devicetree/bindings/arm/keystone/ti,sci.txt create mode 100644 drivers/firmware/ti_sci.c create mode 100644 drivers/firmware/ti_sci.h create mode 100644 include/linux/soc/ti/ti_sci_protocol.h -- 2.10.0
