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

2014-10-05T21:52:17+00:00

commit 0668a4e4d297328ce08b44d91d160537596115e2 upstream.

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

2014-08-07T21:52:37+00:00

commit 9b2a4d35a6ceaf217be61ed8eb3c16986244f640 upstream.

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

2014-08-07T21:52:37+00:00

commit 381676d5e86596b11e22a62f196e192df6091373 upstream.

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: 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.

iio:accel:kxsd9 fix missing mutex unlock

This will leave a lock held after reading from the device, preventing
any further reads.

iio: hid-sensors: accelerometer: Add sensitivity

2013-11-05T23:02:43+00:00

A number of Properties that can be applied to Data Fields are per data
field basis or for all data fields. Adding sensitivity field for all
accelerometer fields, which is most commonly used in currently
available sensor hubs.

iio: hid_Sensors: fix crash during trigger unregister

2013-11-02T19:07:06+00:00

We can't store the trigger instance created by iio_trigger_alloc, in
trig field of iio_device structure. This needs to be stored in the
driver private data. Othewise it can result in crash during module
unload. Hence created a trig_ptr in the common data structure
for each HID sensor IIO driver and storing here.
