25 routed to different processor sub-systems on DRA7xx as they are routed through
26 the Crossbar, a kind of interrupt router/multiplexer. The K3 AM65x and J721E
38 a SoC. The sub-mailboxes are represented as child nodes of this parent node.
41 --------------------
42 - compatible: Should be one of the following,
43 "ti,omap2-mailbox" for OMAP2420, OMAP2430 SoCs
44 "ti,omap3-mailbox" for OMAP3430, OMAP3630 SoCs
45 "ti,omap4-mailbox" for OMAP44xx, OMAP54xx, AM33xx,
47 "ti,am654-mailbox" for K3 AM65x and J721E SoCs
48 "ti,am64-mailbox" for K3 AM64x SoCs
49 - reg: Contains the mailbox register address range (base
51 - interrupts: Contains the interrupt information for the mailbox
54 - #mbox-cells: Common mailbox binding property to identify the number
57 - ti,mbox-num-users: Number of targets (processor devices) that the mailbox
59 - ti,mbox-num-fifos: Number of h/w fifo queues within the mailbox IP block
61 SoC-specific Required properties:
62 ---------------------------------
65 - ti,hwmods: Name of the hwmod associated with the mailbox. This
70 The following are mandatory properties for the K3 AM65x and J721E SoCs only:
71 - interrupt-parent: Should contain a phandle to the TI-SCI interrupt

80 A child node is used for representing the actual sub-mailbox device that is
86 --------------------
87 - ti,mbox-tx: sub-mailbox descriptor property defining a Tx fifo
88 - ti,mbox-rx: sub-mailbox descriptor property defining a Rx fifo
90 Sub-mailbox Descriptor Data
91 ---------------------------
92 Each of the above ti,mbox-tx and ti,mbox-rx properties should have 3 cells of
94 Cell #1 (fifo_id) - mailbox fifo id used either for transmitting
95 (ti,mbox-tx) or for receiving (ti,mbox-rx)
96 Cell #2 (irq_id) - irq identifier index number to use from the parent's
100 Cell #3 (usr_id) - mailbox user id for identifying the interrupt line
104 --------------------
105 - ti,mbox-send-noirq: Quirk flag to allow the client user of this sub-mailbox
108 sub-mailboxes used to communicate with WkupM3 remote
115 "mbox-names" (please see Documentation/devicetree/bindings/mailbox/mailbox.txt
118 the intended sub-mailbox child node to be used for communication. The equivalent
