+* Device tree bindings for Atmel GPBR (General Purpose Backup Registers)
+
+The GPBR are a set of battery-backed registers.
+
+Required properties:
+- compatible: Should be one of the following:
+ "atmel,at91sam9260-gpbr", "syscon"
+ "microchip,sam9x60-gpbr", "syscon"
+ "microchip,sam9x7-gpbr", "microchip,sam9x60-gpbr", "syscon"
+- reg: contains offset/length value of the GPBR memory
+ region.
+
+Example:
+
+gpbr: gpbr@fffffd50 {
+ compatible = "atmel,at91sam9260-gpbr", "syscon";
+ reg = <0xfffffd50 0x10>;
+};
