title: Common K3 TI-SCI bindings

description: |
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.
properties:
ti,sci:
$ref: /schemas/types.yaml#/definitions/phandle
description:
Should be a phandle to the TI-SCI System Controller node
ti,sci-dev-id:
$ref: /schemas/types.yaml#/definitions/uint32
description: |
Should contain the TI-SCI device id corresponding to the device. Please
refer to the corresponding System Controller documentation for valid
values for the desired device.
ti,sci-proc-ids:
description: Should contain a single tuple of <proc_id host_id>.
$ref: /schemas/types.yaml#/definitions/uint32-array
items:
- description: TI-SCI processor id for the remote processor device
- description: TI-SCI host id to which processor control ownership
should be transferred to
