+description:
+  The Axiado mailbox controller provides inter-processor communication
+  channels between subsystems within the Axiado SoC. The hardware has
+  separate TX and RX register regions. Only the RX channels (channels 8-15)
+  generate interrupts; TX channels are purely poll/write-based.

-Texas Instruments' Message Manager Driver
-========================================
-
-The Texas Instruments' Message Manager is a mailbox controller that has
-configurable queues selectable at SoC(System on Chip) integration. The Message
-manager is broken up into queues in different address regions that are called
-"proxies" - each instance is unidirectional and is instantiated at SoC
-integration level to indicate receive or transmit path.
-
-Message Manager Device Node:
-===========================
-Required properties:
---------------------
-- compatible:		Shall be: "ti,k2g-message-manager"
-- reg-names 		queue_proxy_region - Map the queue proxy region.
-			queue_state_debug_region - Map the queue state debug
-			region.
-- reg:			Contains the register map per reg-names.
-- #mbox-cells		Shall be 2. Contains the queue ID and proxy ID in that
-		        order referring to the transfer path.
-- interrupt-names:	Contains interrupt names matching the rx transfer path
-			for a given SoC. Receive interrupts shall be of the
-			format: "rx_<QID>".
-			For ti,k2g-message-manager, this shall contain:
-				"rx_005", "rx_057"
-- interrupts:		Contains the interrupt information corresponding to
-			interrupt-names property.
-
-Example(K2G):
-------------
-
-	msgmgr: msgmgr@2a00000 {
-		compatible = "ti,k2g-message-manager";
-		#mbox-cells = <2>;
-		reg-names = "queue_proxy_region", "queue_state_debug_region";
-		reg = <0x02a00000 0x400000>, <0x028c3400 0x400>;
-		interrupt-names = "rx_005", "rx_057";
-		interrupts = <GIC_SPI 324 IRQ_TYPE_LEVEL_HIGH>,
-			     <GIC_SPI 327 IRQ_TYPE_LEVEL_HIGH>;
-	};
-
-	pmmc: pmmc {
-		[...]
-		mbox-names = "rx", "tx";
-		# RX queue ID is 5, proxy ID is 2
-		# TX queue ID is 0, proxy ID is 0
-		mboxes= <&msgmgr 5 2>,
-			<&msgmgr 0 0>;
-		[...]
-	};
