+title: Generic SYSCON mapped register reset driver
+
+maintainers:
+  - Sebastian Reichel <sre@kernel.org>
+
+description: |+
+  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 SYSCON register map base plus the offset with the value and
+  mask defined in the reboot node. Default will be little endian mode, 32 bit
+  access only. The SYSCON registers map is normally retrieved from the
+  parental dt-node. So the SYSCON reboot node should be represented as a
+  sub-node of a "syscon", "simple-mfd" node. Though the regmap property
+  pointing to the system controller node is also supported.
+
+properties:
+  compatible:
+    const: syscon-reboot
+
+  mask:
+    $ref: /schemas/types.yaml#/definitions/uint32
+    description: Update only the register bits defined by the mask (32 bit).
+
+  offset:
+    $ref: /schemas/types.yaml#/definitions/uint32
+    description: Offset in the register map for the reboot register (in bytes).
+
+  regmap:
+    $ref: /schemas/types.yaml#/definitions/phandle
+    deprecated: true
+    description: |
+      Phandle to the register map node. This property is deprecated in favor of
+      the syscon-reboot node been a child of a system controller node.
