* 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>; };
