-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 8 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:
- mailbox: mailbox@10540000 {
- compatible = "apm,xgene-slimpro-mbox";
- reg = <0x0 0x10540000 0x0 0xa000>;
- #mbox-cells = <1>;
