   12 description: |
   13   This driver gets reboot mode magic value from reboot-mode driver
   14   and stores it in a SYSCON mapped register. Then the bootloader
   15   can read it and take different action according to the magic
   16   value stored. The SYSCON mapped register is retrieved from the
   17   parental dt-node plus the offset. So the SYSCON reboot-mode node
   18   should be represented as a sub-node of a "syscon", "simple-mfd" node.
