Martin Kelly 0d92aa2c27 iio:magnetometer: st_magn: add LSM9DS1 support
Update the sensor settings to support the LSM9DS1 sensor. Although the
LSM9DS1 accelerometer and gyroscope are coupled together to use the same
FIFO, the magnetometer is separate and can be cleanly supported without
refactoring the existing driver.

Arnd Bergmann 9b090a98e9 iio: st_magn: always define ST_MAGN_TRIGGER_SET_STATE
When CONFIG_IIO_TRIGGER is enabled but CONFIG_IIO_BUFFER is
not, we get a build error in the st_magn driver:

drivers/iio/magnetometer/st_magn_core.c:573:23: error: 'ST_MAGN_TRIGGER_SET_STATE' undeclared here (not in a function)
  .set_trigger_state = ST_MAGN_TRIGGER_SET_STATE,
                       ^~~~~~~~~~~~~~~~~~~~~~~~~

Apparently, this ST_MAGN_TRIGGER_SET_STATE macro was meant to
be set to NULL when the definition is not available because
st_magn_buffer.c is not compiled, but the alternative definition
was not included in the original patch. This adds it.

Linus Walleij 1038a68728 iio: magnetometer: support for lsm303dlh
The LSM303DLH accelerometer/magnetometer has a different
device identification method than using register 0x0f, instead
three registers contain a magic value. We rely on WhoAmI
to be zero for this variant.
