This config adds ACPI operation region support for TI TPS68470 PMIC.
TPS68470 device is an advanced power management unit that powers

general purpose indicators.
This driver enables ACPI operation region support control voltage
regulators and clocks.
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.
