+ TPS68470 device is an advanced power management unit that powers
+ a Compact Camera Module (CCM), generates clocks for image sensors,
+ drives a dual LED for flash and incorporates two LED drivers for
+ 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.
