12description: |
13  The TI K3 family of SoCs usually have a central System Controller Processor
14  that is responsible for managing various SoC-level resources like clocks,
15  resets, interrupts etc. The communication with that processor is performed
16  through the TI-SCI protocol.
17
18  Each specific device management node like a clock controller node, a reset
19  controller node or an interrupt-controller node should define a common set
20  of properties that enables them to implement the corresponding functionality
21  over the TI-SCI protocol. The following are some of the common properties
22  needed by such individual nodes. The required properties for each device
23  management node is defined in the respective binding.
