1The APM X-Gene SLIMpro mailbox is used to communicate messages between
2the ARM64 processors and the Cortex M3 (dubbed SLIMpro). It uses a simple
3interrupt based door bell mechanism and can exchange simple messages using the
4internal registers.
5
6There are total of 8 interrupts in this mailbox. Each used for an individual
7door bell (or mailbox channel).
8
9Required properties:
10- compatible:	Should be as "apm,xgene-slimpro-mbox".
11
12- reg:		Contains the mailbox register address range.
13
14- interrupts:	8 interrupts must be from 0 to 7, interrupt 0 define the
15		the interrupt for mailbox channel 0 and interrupt 1 for
16		mailbox channel 1 and so likewise for the reminder.
17
18- #mbox-cells:	only one to specify the mailbox channel number.

21
22Mailbox Node:
23		mailbox: mailbox@10540000 {
24			compatible = "apm,xgene-slimpro-mbox";
25			reg = <0x0 0x10540000 0x0 0xa000>;
26			#mbox-cells = <1>;
27			interrupts =  	<0x0 0x0 0x4>,
28					<0x0 0x1 0x4>,
29					<0x0 0x2 0x4>,
30					<0x0 0x3 0x4>,
31					<0x0 0x4 0x4>,
32					<0x0 0x5 0x4>,
33					<0x0 0x6 0x4>,
34					<0x0 0x7 0x4>,
