If you say yes here you get support for the TPS68470 series of
Power Management / LED chips.

These include voltage regulators, LEDs and other features
that are often used in portable devices.

This option is a bool as it provides an ACPI operation
region, which must be available before any of the devices
using this are probed. This option also configures the
designware-i2c driver to be built-in, for the same reason.
