   13   This is a generic reset driver using syscon to map the reset register.
   14   The reset is generally performed with a write to the reset register
   15   defined by the SYSCON register map base plus the offset with the value and
   16   mask defined in the reboot node. Default will be little endian mode, 32 bit
   17   access only. The SYSCON registers map is normally retrieved from the
   18   parental dt-node. So the SYSCON reboot node should be represented as a
   19   sub-node of a "syscon", "simple-mfd" node. Though the regmap property
   20   pointing to the system controller node is also supported.
