-Generic SYSCON mapped register reset driver
-
-This is a generic reset driver using syscon to map the reset register.
-The reset is generally performed with a write to the reset register
-defined by the register map pointed by syscon reference plus the offset
-with the value and mask defined in the reboot node.
-
-Required properties:
-- compatible: should contain "syscon-reboot"
-- regmap: this is phandle to the register map node
-- offset: offset in the register map for the reboot register (in bytes)
-- value: the reset value written to the reboot register (32 bit access)
-
-Optional properties:
-- mask: update only the register bits defined by the mask (32 bit)
-
-Legacy usage:
-If a node doesn't contain a value property but contains a mask property, the
-mask property is used as the value.
-
-Default will be little endian mode, 32 bit access only.
-
-Examples:
-
-	reboot {
-	   compatible = "syscon-reboot";
-	   regmap = <&regmapnode>;
-	   offset = <0x0>;
-	   mask = <0x1>;
-	};
