+title: Generic SYSCON reboot mode driver
+
+maintainers:
+  - Sebastian Reichel <sre@kernel.org>
+
+description: |
+  This driver gets reboot mode magic value from reboot-mode driver
+  and stores it in a SYSCON mapped register. Then the bootloader
+  can read it and take different action according to the magic
+  value stored. The SYSCON mapped register is retrieved from the
+  parental dt-node plus the offset. So the SYSCON reboot-mode node
+  should be represented as a sub-node of a "syscon", "simple-mfd" node.
