+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.
