9b2a4d35a6 iio:bma180: Missing check for frequency fractional part
val2 should be zero

This will make no difference for correct inputs but will reject
incorrect ones with a decimal part in the value written to the sysfs
interface.

381676d5e8 iio:bma180: Fix scale factors to report correct acceleration units
The userspace interface for acceleration sensors is documented as using
m/s^2 units [Documentation/ABI/testing/sysfs-bus-iio]

The fullscale raw values for the BMA80 corresponds to -/+ 1, 1.5, 2, etc G
depending on the selected mode.

The scale table was converting to G rather than m/s^2.
Change the scaling table to match the documented interface.

See commit 71702e6e, iio: mma8452: Use correct acceleration units,
for a related fix.

5585215b6d iio:accel:bma180: Use modifier instead of index in channel specification
This driver was not complying with the ABI and the purpose of this patch
is to bring it inline so that userspace will correctly identify the channels.

Should use channel modifiers (X/Y/Z), not channel indices
timestamp channel has scan index 3, not 4

7d7feae706 iio:accel:bma180 replaces IIO_ST macro with explicit entries to struct scan_type
The IIO_ST macro no longer covers all the elements of struct scan_type
and has this has lead to some bugs being introduced.

The drivers are easier to follow with this structure being directly
filled so that is now preferred.
