-	depends on SPI && SYSFS
-	---help---
-	If you say yes here you get support for the Analog Devices
-	ADIS16250/16255 Low Power Gyroscope. The driver exposes
-	orientation and gyroscope value, as well as sample rate
-	to the sysfs.

-	This driver can also be built as a module. If so, the module
-	will be called adis16255.
