+          Say yes here to build support for STMicroelectronics pressures:
+          LPS331AP.
+
+          This driver can also be built as a module. If so, will be created
+          these modules:
+          - st_pressure (core functions for the driver [it is mandatory]);
+          - st_pressure_i2c (necessary for the I2C devices [optional*]);
+          - st_pressure_spi (necessary for the SPI devices [optional*]);
+
+          (*) one of these is necessary to do something.
