25 routed to different processor sub-systems on DRA7xx as they are routed through
32 Mailbox Device Node:
34 A Mailbox device node is used to represent a Mailbox IP instance/cluster within
35 a SoC. The sub-mailboxes are represented as child nodes of this parent node.
38 --------------------
39 - compatible: Should be one of the following,
40 "ti,omap2-mailbox" for OMAP2420, OMAP2430 SoCs
41 "ti,omap3-mailbox" for OMAP3430, OMAP3630 SoCs
42 "ti,omap4-mailbox" for OMAP44xx, OMAP54xx, AM33xx,
44 "ti,am654-mailbox" for K3 AM65x and J721E SoCs
45 - reg: Contains the mailbox register address range (base
47 - interrupts: Contains the interrupt information for the mailbox
50 - #mbox-cells: Common mailbox binding property to identify the number
53 - ti,mbox-num-users: Number of targets (processor devices) that the mailbox
55 - ti,mbox-num-fifos: Number of h/w fifo queues within the mailbox IP block
57 SoC-specific Required properties:
58 ---------------------------------
61 - ti,hwmods: Name of the hwmod associated with the mailbox. This
62 should be defined in the mailbox node only if the node
63 is not defined as a child node of a corresponding sysc
64 interconnect node.
67 - interrupt-parent: Should contain a phandle to the TI-SCI interrupt
68 controller node that is used to dynamically program
72 Documentation/devicetree/bindings/interrupt-controller/ti,sci-intr.yaml
76 A child node is used for representing the actual sub-mailbox device that is
78 Each child node should have a unique node name across all the different
82 --------------------
83 - ti,mbox-tx: sub-mailbox descriptor property defining a Tx fifo
84 - ti,mbox-rx: sub-mailbox descriptor property defining a Rx fifo
86 Sub-mailbox Descriptor Data
87 ---------------------------
88 Each of the above ti,mbox-tx and ti,mbox-rx properties should have 3 cells of
90 Cell #1 (fifo_id) - mailbox fifo id used either for transmitting
91 (ti,mbox-tx) or for receiving (ti,mbox-rx)
92 Cell #2 (irq_id) - irq identifier index number to use from the parent's
96 Cell #3 (usr_id) - mailbox user id for identifying the interrupt line
100 --------------------
101 - ti,mbox-send-noirq: Quirk flag to allow the client user of this sub-mailbox
104 sub-mailboxes used to communicate with WkupM3 remote
111 "mbox-names" (please see Documentation/devicetree/bindings/mailbox/mailbox.txt
113 mailbox controller device node and an args specifier that will be the phandle to
114 the intended sub-mailbox child node to be used for communication. The equivalent
115 "mbox-names" property value can be used to give a name to the communication channel
