+The APM X-Gene SLIMpro mailbox is used to communicate messages between
+the ARM64 processors and the Cortex M3 (dubbed SLIMpro). It uses a simple
+interrupt based door bell mechanism and can exchange simple messages using the
+internal registers.
+
+There are total of 7 interrupts in this mailbox. Each used for an individual
+door bell (or mailbox channel).
+
+Required properties:
+- compatible: Should be as "apm,xgene-slimpro-mbox".
+
+- reg: Contains the mailbox register address range.
+
+- interrupts: 8 interrupts must be from 0 to 7, interrupt 0 define the
+ the interrupt for mailbox channel 0 and interrupt 1 for
+ mailbox channel 1 and so likewise for the reminder.
+
+- #mbox-cells: only one to specify the mailbox channel number.
+
+Example:
+
+Mailbox Node:
+ slimpro-mbox: slimpro-mbox@10540000 {
+ compatible = "apm,xgene-slimpro-mbox";
+ reg = <0x0 0x10540000 0x0 0xa000>;

Thanks, Rob.
I will change the node name to mailbox@10540000 in the document and DT
as well in the next version.
