2013-12-17iio:mag:mag3110 replaces IIO_ST macro with explicit entries to struct scan_typeJonathan Cameron
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. Signed-off-by: Jonathan Cameron <jic23@kernel.org> Acked-by: Lars-Peter Clausen <lars@metafoo.de>

2013-11-09iio: hid-sensors: magnetometer : Add sensitivitySrinivas Pandruvada
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.

2013-11-02iio: hid_Sensors: fix crash during trigger unregisterSrinivas Pandruvada
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.

2013-10-20iio: Correct description how to convert microtesla to gaussPeter Meerwald
this just fixes the comment; however, I'm not sure if the driver reports measurements correctly; the raw values are 0.3 uT / LSB; IIO is supposed to report magnetic fields in Gauss, so the scale should be around 1/300 (ignoring ASA) -- but value and scale are returned as VAL_INT Signed-off-by: Peter Meerwald <pmeerw@pmeerw.net> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
2013-10-16iio:st_magn: Remove redundant call to iio_sw_buffer_preenable().Lars-Peter Clausen
The equivalent of iio_sw_buffer_preenable() is now done in the IIO buffer core, so there is no need to do this from the driver anymore. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Cc: Denis Ciocca <denis.ciocca@st.com> Signed-off-by: Jonathan Cameron <jic23@kernel.org>

2013-09-21iio: magn-core: st: Clean up error handling in probe()Lee Jones

2013-08-03iio: Add a comment to about alphabetical order to Kconfigs and MakefilesLars-Peter Clausen
Keeping Makefile and Kconfig entries in alphabetical order usually works better than just appending new entries at the end, since it reduces the amount of conflicts. This patch adds a comment to the IIO Kconfig and Makefile files to document that the entries should be kept in alphabetical order. Also reorder those entries which weren't in alphabetical order yet.

2013-08-03iio: hid-sensor-magn-3d: add module alias for autoloadAlexander Holler
Add a MODULE_DEVICE_TABLE in order to let hotplug mechanisms automatically load the driver.

CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, and __devexit from these drivers.
