The TI K3 family of SoCs usually have a central System Controller Processor
|
||
|
|
that is responsible for managing various SoC-level resources like clocks,
|
||
|
|
resets, interrupts etc. The communication with that processor is performed
|
||
|
|
through the TI-SCI protocol.
|
||
|
|
|
||
|
|
Each specific device management node like a clock controller node, a reset
|
||
|
|
controller node or an interrupt-controller node should define a common set
|
||
|
|
of properties that enables them to implement the corresponding functionality
|
||
|
|
over the TI-SCI protocol. The following are some of the common properties
|
||
|
|
needed by such individual nodes. The required properties for each device
|
||
|
|
management node is defined in the respective binding.
