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 PM domain node represents the global PM domain managed by the TI-SCI
|
|
controller. Since this relies on the TI SCI protocol to communicate with
|
|
the TI-SCI controller, it must be a child of the TI-SCI controller node.

description:
|
|
The two cells represent values that the TI-SCI controller defines.
|
|
|
|
The first cell should contain the device ID.
|
|
|
|
The second cell, if cell-value is 2, should be one of the following
|
|
TI_SCI_PD_EXCLUSIVE - Allows the device to be exclusively controlled
|
|
or
|
|
TI_SCI_PD_SHARED - Allows the device to be shared by multiple hosts.
|
|
Please refer to dt-bindings/soc/ti,sci_pm_domain.h for the definitions.
|
|
|
|
Please see https://software-dl.ti.com/tisci/esd/latest/index.html for
|
|
protocol documentation for the values to be used for different devices.
