Subject: [PATCH v4 3/6] dt-bindings: remoteproc: Add common TI SCI rproc bindings
Date: Fri, 17 Jul 2020 18:47:57 -0500
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.

Signed-off-by: Suman Anna <s-anna@ti.com>

+title: Common TI K3 remote processor device bindings
+

+  - Suman Anna <s-anna@ti.com>
+
+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
