[PATCH v3 03/22] dt-bindings: arm: scmi: add ARM MHU specific mailbox client bindings

Show all headers | View raw

This patch adds ARM MHU specific mailbox client bindings to support
SCMI. Since SCMI specification just requires doorbell mechanism from
mailbox controllers, we add mailbox data to specify the doorbell bit(s).

+ARM MHU mailbox client bindings for SCMI Message Protocol
+----------------------------------------------------------
+
+This binding is intended to define the ARM MHU specific extensions to
+the generic SCMI bindings[2].
+
+Required properties:
+
+The scmi node with the following properties shall be under the /firmware/ node.
+
+- compatible : shall be "arm,scmi" and "arm,mhu-scmi"
+- mbox-data : For each phandle listed in mboxes property, an unsigned 32-bit
+	      data as expected by the mailbox controller
+
+See [1] for details on all other required/optional properties of the generic
+mailbox controller and [2] for generic SCMI bindings.
