Just like syscon-reboot device, the syscon-poweroff is supposed to be a child of syscon node, thus we can take the same approach as syscon-poweroff: deprecate the 'regmap' field in favor of taking it from the parent's node.

|
This is a generic poweroff driver using syscon to map the poweroff register.
|
|
The poweroff is generally performed with a write to the poweroff register
|
|
defined by the register map pointed by syscon reference plus the offset
|
|
with the value and mask defined in the poweroff node.
|
|
Default will be little endian mode, 32 bit access only.
|
|
The SYSCON register map is normally retrieved from the parental dt-node. So
|
|
the SYSCON poweroff node should be represented as a sub-node of a "syscon",
|
|
"simple-mfd" node.
