1* Device tree bindings for Atmel Bus Matrix
2
3The Bus Matrix registers are used to configure Atmel SoCs internal bus
4behavior (master/slave priorities, undefined burst length type, ...)
5
6Required properties:
7- compatible:		Should be one of the following
8			"atmel,at91sam9260-matrix", "syscon"
9			"atmel,at91sam9261-matrix", "syscon"
10			"atmel,at91sam9263-matrix", "syscon"
11			"atmel,at91sam9rl-matrix", "syscon"
12			"atmel,at91sam9g45-matrix", "syscon"
13			"atmel,at91sam9n12-matrix", "syscon"
14			"atmel,at91sam9x5-matrix", "syscon"
15			"atmel,sama5d3-matrix", "syscon"
16			"microchip,sam9x60-matrix", "syscon"
17			"microchip,sam9x7-matrix", "atmel,at91sam9x5-matrix", "syscon"
18- reg:			Contains offset/length value of the Bus Matrix
19			memory region.

21Example:
22
23matrix: matrix@ffffec00 {
24	compatible = "atmel,sama5d3-matrix", "syscon";
25	reg = <0xffffec00 0x200>;
26};
