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.

  compatible:
    const: syscon-reboot-mode
