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-accel-3d: add module alias for autoloadAlexander Holler
Add a MODULE_DEVICE_TABLE in order to let hotplug mechanisms automatically load the driver. This makes it also possible to use the usual driver name instead of HID-SENSOR-2000xx which isn't very descriptive in kernel messages.

struct and added support on one-shot sysfs reads to 3 byte channel This patch introduce num_data_channels variable on st_sensors struct to manage different type of channels (size or number) in st_sensors_get_buffer_element function. Removed ST_SENSORS_NUMBER_DATA_CHANNELS and ST_SENSORS_BYTE_FOR_CHANNEL and used struct iio_chan_spec const *ch to catch data. Added 3 byte channel data support on one-shot reads.

2013-05-22iio: STMicroelectronics: remove three useless selectsPaul Bolle
Drivers for STMicroelectronics accelerometers, gyroscopes, and magnetometers were added in v3.9. They all have a (similar) select statement in their Kconfig files for a non-existant Kconfig symbol. These select statements can safely be removed. Signed-off-by: Paul Bolle <pebolle@tiscali.nl> Acked-by: Denis Ciocca <denis.ciocca@st.com> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
2013-03-25iio:trigger: Introduce iio_tigger_{set,get}_drvdataLars-Peter Clausen
Introduce iio_tigger_{set,get}_drvdata which allows to attach driver specific data to a trigger. The functions wrap access to the triggers private_data field and all current users are updated to use iio_tigger_{set,get}_drvdata instead of directly accessing the private_data field. This is the first step towards removing the private_data field from the iio_trigger struct. The following coccinelle script has been used to update the drivers: <smpl> @@ struct iio_trigger *trigger; expression priv; @@ -trigger->private_data = priv +iio_trigger_set_drv_data(trigger, priv) @@ struct iio_trigger *trigger; @@ -trigger->private_data +iio_trigger_get_drv_data(trigger) </smpl> Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Jonathan Cameron <jic23@kernel.org>

2013-02-09iio:st_sensors fix build when !CONFIG_IIO_TRIGGERJonathan Cameron
Partly a case of removing unused headers and partly a case of ifdefing out the iio_trigger_ops structures. This has come about because of an 'unusual' separation of code in this driver.

Well, the omapdrm fixes aren't really "small" but they were waiting on a number of other drm patches to go in through the drm tree, and got delayed by my vacation over the holidays. They are totally self-contained, everyone involved have acked them, and they fix issues that people have been having with the driver.

2013-01-03Drivers: iio: remove __dev* attributes.Greg Kroah-Hartman
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. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand.
