    iio: pressure: bmp280: add SPI interface driver · b26b4e91
    Linus Walleij authored
    This patch mimics the SPI functionality found in the misc driver in
    drivers/misc/bh085-spi.c to make it possible to reuse the existing
    BMP280/BMP180/BMP085 driver with all clients of the other driver.
    The adoption is straight-forward since like the other driver, it is
    a simple matter of using regmap.
    
    This driver is also so obviously inspired/copied from the old misc
    driver in drivers/misc/bmp085.c that I just took the liberty to
    add in the authors of the other drivers + self in the core driver
    file.
    
    The MISC driver also supports a variant named "BMP181" so include
    that here to be complete in comparison to the old driver.
    
    The bus mapping code for SPI was written by Akinobu Mita.
