[PATCH] dt-bindings: mfd: atmel,at91sam9260: Convert to json schema

[Charan Pedumuru]

Convert old text based binding to json schema.
Changes during conversion:
Add a fallback for all compatibles as the IP core is compatible
with `syscon`.

+
+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 at ffffec00 {
-	compatible = "atmel,sama5d3-matrix", "syscon";
-	reg = <0xffffec00 0x200>;
-};
