iio: Fix endianness issue in ak8975_read_axis()

2014-06-26T19:15:42+00:00

commit 8ba42fb7b17649c9ab5b5e79d4e90370a0b4645e upstream.

i2c_smbus_read_word_data() does host endian conversion already,
no need for le16_to_cpu()

iio: ak8975: Fix calculation formula for convert micro tesla to gauss unit

2014-02-08T10:28:05+00:00

This effects the reported scale of the raw values, and thus userspace
applications that use this value.

One micro tesla equal 0.01 gauss. So I have fixed calculation formula And add RAW_TO_GAUSS macro.
ASA is in the range of 0 to 255. If multiply 0.003, calculation result(in_magn_[*]_scale) is
always 0. So multiply 3000 and return and IIO_VAL_INT_PLUS_MICRO.
As a result, read_raw call back function return accurate scale value.

iio:mag:mag3110 replaces IIO_ST macro with explicit entries to struct scan_type

2013-12-17T20:55:50+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: hid-sensors: magnetometer : Add sensitivity

2013-11-09T13:51:23+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
magnetometer 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.
