iio: imu: Add support for Kionix KMX61 sensor
Minimal implementation for KMX61 6-axis accelerometer/magnetometer. It exports raw accel/magn readings together with scale and sampling frequency. This driver uses two IIO devices one for accelerometer and one for magnetometer. Datasheet will be available at: http://www.kionix.com/6-axis-accelerometer-magnetometer/kmx61 Signed-off-by: Daniel Baluta <daniel.baluta@intel.com> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
