* iio: pressure: mpl115: support MPL115A1Akinobu Mita2016-01-30
mpl115 driver currently supports i2c interface (MPL115A2). There is also SPI version (MPL115A1). The difference between them is only physical transport so we can easily support both while sharing most of the code. Split the driver into a core support module and one module each for I2C and SPI support.
