|
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.
