iio: st_sensors: Fix buffer copy

2014-11-13T18:02:41+00:00

commit 4250c90b30b8bf2a1a21122ba0484f8f351f152d upstream. Use byte_for_channel as iterator to properly initialize the buffer. Signed-off-by: Robin van der Gracht Acked-by: Denis Ciocca Signed-off-by: Jonathan Cameron Signed-off-by: Jiri Slaby

iio: st_sensors: Fix indio_dev->trig assignment

2014-10-13T13:41:14+00:00

commit f0e84acd7056e6d7ade551c6439531606ae30a46 upstream. This can result in wrong reference count for trigger device, call iio_trigger_get to increment reference.

iio: hid_Sensors: fix crash during trigger unregister

2014-10-13T13:41:11+00:00

commit ec7f68e07bf10198717b7824c78201b46bbf1956 upstream. 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. Signed-off-by: Srinivas Pandruvada Signed-off-by: Jonathan Cameron Signed-off-by: Jiri Slaby

iio: Add a comment to about alphabetical order to Kconfigs and Makefiles

2013-08-03T17:40:36+00:00

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.

iio: Added ST-sensors platform data to select the DRDY interrupt pin

2013-08-03T17:40:28+00:00

This patch add support to redirect the DRDY interrupt on INT1 or INT2 on accelerometer and pressure sensors. Signed-off-by: Denis Ciocca Signed-off-by: Jonathan Cameron

iio:common: Removed stuff macros, added num_data_channels on st_sensors struct and added support on one-shot sysfs reads to 3 byte channel

2013-06-05T17:41:23+00:00

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.

iio:trigger: Introduce iio_tigger_{set,get}_drvdata

2013-03-25T21:06:09+00:00

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: @@ 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) Signed-off-by: Lars-Peter Clausen Signed-off-by: Jonathan Cameron

Merge tag 'iio-for-3.10a' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next

2013-03-25T17:50:03+00:00

Jonathan writes: First set of IIO new drivers and cleanup for the 3.10 cycle. New stuff 1) Add OF support for specifying mappings between iio devices and their in kernel consumers. 2) Driver for AD7923 (extra functionality and support for ad7904, ad7914 and ad7924 added later in series) 3) Driver for Exynos adc (dt suppor for phy added later in series). 4) Make iio_push_event save IRQ context - necessary if it is to be used within an interrupt handler. Users of this functionality to follow. 5) For iio use the device tree node name to provide the hwmon name attribute if available. Removal and moves out of staging 1) Drop the adt7410 driver from IIO now that there is a hmwon driver with equivalent support. This device is very much targeted at hardware monitoring so hwmon is a more appropriate host for the driver. 2) Move iio_hwmon driver to drivers/hwmon. Cleanups 1) Minor cleanup in ST common library. 2) Large set of patches to break the info_mask element which previously used odd and even bits to specify if a channel attribute was either shared across similar channels or specific to only one. Now we have two bitmaps, one for those parameters that are specific to this channel and one for those shared by all channels with the same type as this one. This has no effect on the userspace abi. It simplifies the core code and provides more space for new channel parameters. It has been on the todo list for a long time! Conflicts: drivers/iio/dac/ad5064.c
