title: Generic SYSCON mapped register reset driver
maintainers:

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 register map pointed by syscon reference plus the offset
with the value and mask defined in the reboot node.
Default will be little endian mode, 32 bit access only.

compatible:
const: syscon-reboot
mask:

offset:
