|
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.

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 http://processors.wiki.ti.com/index.php/TISCI for
|
|
protocol documentation for the values to be used for different devices.
