The Dell Systems Management Base Driver provides a sysfs interface
for systems management software to perform System Management
Interrupts (SMIs) and Host Control Actions (system power cycle or
power off after OS shutdown) on certain Dell systems.

See Documentation/driver-api/dcdbas.rst for more details on the driver
and the Dell systems on which Dell systems management software makes
use of this driver.

Say Y or M here to enable the driver for use by Dell systems
management software such as Dell OpenManage.
