Say yes here to build support for the Low Resolution
Analog-to-Digital Converter (LRADC) found on the i.MX23 and i.MX28
processors. This driver provides common support for accessing the
device, additional drivers must be enabled in order to use the
functionality of the device:
mxs-lradc-adc for ADC readings
mxs-lradc-ts for touchscreen support

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