title: TI-SCI reset controller node bindings
- Nishanth Menon <>
description: |
Some TI SoCs contain a system controller (like the Power Management Micro
Controller (PMMC) on Keystone 66AK2G SoC) that are responsible for controlling
the state of the various hardware modules present on the SoC. Communication
between the host processor running an OS and the system controller happens
through a protocol called TI System Control Interface (TI-SCI protocol).
This reset controller node uses the TI SCI protocol to perform the reset
management of various hardware modules present on the SoC. Must be a child
node of the associated TI-SCI system controller node.
pattern: "^reset-controller$"
const: ti,sci-reset
const: 2
The two cells represent values that the TI-SCI controller defines.
The first cell should contain the device ID.
The second cell should contain the reset mask corresponding to the device
used by system controller.
Please see for
protocol documentation for the values to be used for different devices.
