Subject: [PATCH v4 3/6] dt-bindings: remoteproc: Add common TI SCI rproc bindings
Date: Fri, 17 Jul 2020 18:47:57 -0500 [thread overview]
Message-ID: <20200717234800.9423-4-s-anna@ti.com> (raw)
In-Reply-To: <20200717234800.9423-1-s-anna@ti.com>
Add a bindings document that lists the common TI SCI properties
used by the K3 R5F and DSP remoteproc devices.

+title: Common TI K3 remote processor device bindings

+
+description: |
+ The TI K3 family of SoCs usually have one or more remote processor sub-systems
+ like the dual-core R5F sub-system or a C66x or C71x DSP processor subsystem.
+ The device management of these remote processors is managed by a dedicated
+ System Processor, and the communication with that processor is managed through
+ the TI-SCI protocol.
+
+ Each remote processor device node should define a common set of properties
+ that allows the System Processor firmware to perform the device management
+ such as powering the IPs, asserting/deasserting the resets for each of these
+ processors.
+
+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 remote processor
+ core. Please refer to the corresponding System Controller documentation
+ for valid values.
+
+ 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
+
+required:
+ - ti,sci
+ - ti,sci-dev-id
+ - ti,sci-proc-ids
