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.
The specifications can be downloaded from:
