+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.
+
+Examples:
+ regmapnode {
+ compatible = "apm,xgene-scu","syscon";
+ reg = <0xXXXXXXXX 0xXXXXXXXX>;
+ }
+
+ reboot {
+ compatible = "syscon-reboot";
+ regmap = <®mapnode>;
+ offset = <0x0>;
+ mask = <0x1>;
+ };
