iio: accel: bma180: Fix indio_dev->trig assignment

2014-08-25T20:48:04+00:00

This can result in wrong reference count for trigger device, call
iio_trigger_get to increment reference.
Refer to http://www.spinics.net/lists/linux-iio/msg13669.html for discussion
with Jonathan.

iio:bma180: Missing check for frequency fractional part

2014-07-20T16:39:47+00:00

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.

iio:bma180: Fix scale factors to report correct acceleration units

2014-07-20T16:38:39+00:00

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.

iio:accel:bma180: Make LOW_PASS_FILTER_3DB_FREQUENCY shared_by_type

2014-02-15T11:05:02+00:00

the property is not per-channel, but shared by type

iio:accel:bma180: Use modifier instead of index in channel specification

2014-02-08T11:31:50+00:00

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

iio:accel:bma180 replaces IIO_ST macro with explicit entries to struct scan_type

2013-12-17T20:55:01+00:00

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.

Merge 3.12-rc2 into staging-next.

2013-09-25T15:59:04+00:00

This resolves the merge problem with two iio drivers that Stephen
Rothwell pointed out.

iio: Remove unnecessary casts for iio_push_to_buffers()

2013-09-15T18:05:07+00:00

Now that iio_push_to_buffers() takes a void pointer for the data parameter we
can remove those casts to u8*.
