+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 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)
+- mask: the reset value written to the reboot register (32 bit access)
+Default will be little endian mode, 32 bit access only.
+ reboot {
+ compatible = "syscon-reboot";
+ regmap = <&regmapnode>;
+ offset = <0x0>;
+ mask = <0x1>;
+ };
