dt-bindings: mfd: atmel,at91sam9260: Convert to YAML schema 



Changes during conversion:

Add a missing fallback `atmel,at91sam9x5-matrix` for
`microchip,sam9x60-matrix` which is not defined in the text binding.

title: Microchip AT91 Bus Matrix



maintainers:

  - Nicolas Ferre <nicolas.ferre@microchip.com>



description:

  The Bus Matrix (MATRIX) implements a multi-layer AHB, based on the

  AHB-Lite protocol, that enables parallel access paths between multiple

  masters and slaves in a system, thus increasing the overall bandwidth.

* Device tree bindings for Atmel Bus Matrix



The Bus Matrix registers are used to configure Atmel SoCs internal bus

behavior (master/slave priorities, undefined burst length type, ...)



Required properties:

- compatible:		Should be one of the following

			"atmel,at91sam9260-matrix", "syscon"

			"atmel,at91sam9261-matrix", "syscon"

			"atmel,at91sam9263-matrix", "syscon"

			"atmel,at91sam9rl-matrix", "syscon"

			"atmel,at91sam9g45-matrix", "syscon"

			"atmel,at91sam9n12-matrix", "syscon"

			"atmel,at91sam9x5-matrix", "syscon"

			"atmel,sama5d3-matrix", "syscon"

			"microchip,sam9x60-matrix", "syscon"

			"microchip,sam9x7-matrix", "atmel,at91sam9x5-matrix", "syscon"

- reg:			Contains offset/length value of the Bus Matrix

			memory region.



Example:



matrix: matrix@ffffec00 {

	compatible = "atmel,sama5d3-matrix", "syscon";

	reg = <0xffffec00 0x200>;

};
