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>
2013-03-25Merge tag 'iio-for-3.10a' of ↵Greg Kroah-Hartman
git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next 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

2013-01-07Merge branch 'staging-linus' into staging-nextGreg Kroah-Hartman
This is to get the comedi fixes, and resolve the issue in comdi_test.c and comedi_fops.c that were caused by changes in both branches. It also allows the fwserial driver changes to be applied, as they required the fixes that are in staging-linus. Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2013-01-06hid: iio: rename struct hid_sensor_iio_common to hid_sensor_commonAlexander Holler
The structure with common attributes for hid-sensors isn't specific to the iio-subsystem, so rename it to hid_sensor_common. Signed-off-by: Alexander Holler <holler@ahsoftware.de> Acked-by: Jiri Kosina <jkosina@suse.cz> Signed-off-by: Jonathan Cameron <jic23@kernel.org>

2012-12-27iio: hid-sensors: respect CONFIG_IIO_TRIGGERAlexander Holler
Not much to say, without that change, hid-sensor-trigger will be always compiled if HID_SENSOR_IIO_COMMON is selected which fails if CONFIG_IIO_TRIGGER is not set because CONFIG_IIO_CONSUMERS_PER_TRIGGER will not be defined.

2012-09-22iio: hid-sensors: Prevent crash during hot-unplugSrinivas Pandruvada
When hid sensor hub is unplugged, there is a crash in iio_device_unregister_trigger_consumer. In a typical IIO driver when remove is called, it will unregister and free trigger and then it will call iio_device_free. The function iio_trigger_free() will free the allocated memory for trigger. If this trigger was assigned to iio_dev->trig, then it should be set to NULL. Othewise when iio_device_free() is called later, it finally calls iio_device_unregsister_trigger(), which checks for if (indio_dev->trig) iio_trigger_put(indio_dev->trig); If indio_dev->trig is not set to NULL, it calls iio_trigger_put on a bad pointer causing crash. This scenerio can happen in any driver, which is storing trigger pointer in iio_dev structure and following current procedure during remove.

2012-09-06iio: hid-sensors: Common attribute and triggersrinivas pandruvada
This patch contains the common code, which is used by all HID sensors. There are some common set of attributes, which every hid sensor needs it. This patch contains all such attributes processing. Also the trigger interface is common among all HID sensors. This patch contains common trigger functions utilized by all HID sensors.
