iio: accel: mma9551: split driver to expose mma955x api Freescale has the MMA955xL family of devices that use the same communication protocol (based on i2c messages): http://www.freescale.com/files/sensors/doc/data_sheet/MMA955xL.pdf. To support more devices from this family, we need to split the mma9551 driver so we can export the common functions that will be used by other mma955x drivers.

iio: add driver for Freescale MMA9553 Add support for Freescale MMA9553L Intelligent Pedometer Platform. The following functionalities are supported: - step counter (counts the number of steps using a HW register) - step detector (generates an iio event at every step the user takes) - activity recognition (rest, walking, jogging, running) - speed - calories - distance To get accurate pedometer results, the user's height, weight and gender need to be configured.
