This driver supports multiple devices like mma8653,
mma8652, mma8452, mma8453 and fxls8471. Almost all
these devices have more than one event.
Current driver design hardcodes the event specific
information, so only one event can be supported by this
driver at any given time.
Also current design doesn't have the flexibility to
add more events.
This patch improves by detaching the event related
information from chip_info struct,and based on channel
type and event direction the corresponding event
configuration registers are picked dynamically.
Hence both transient and freefall events can be
handled in read/write callbacks.
Changes are thoroughly tested on fxls8471 device on imx6UL
Eval board using iio_event_monitor user space program.
After this fix both Freefall and Transient events are
handled by the driver without any conflicts.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
