iio: inkern: api for manipulating ext_info of iio channels

2017-06-03T10:29:26+00:00

Extend the inkern api with functions for reading and writing ext_info of iio channels. Acked-by: Jonathan Cameron Signed-off-by: Peter Rosin Signed-off-by: Greg Kroah-Hartman

iio: inkern: add helpers to query available values from channels

2016-11-13T11:40:26+00:00

Specifically a helper for reading the available maximum raw value of a channel and a helper for forwarding read_avail requests for raw values from one iio driver to an iio channel that is consumed. These rather specific helpers are in turn built with generic helpers making it easy to build more helpers for available values as needed. Signed-off-by: Peter Rosin Signed-off-by: Jonathan Cameron

iio: inkern: add iio_read_channel_offset helper

2016-09-27T19:33:02+00:00

Allow access to underlying channel IIO_CHAN_INFO_OFFSET from a consumer. Signed-off-by: Matt Ranostay Signed-off-by: Jonathan Cameron

iio: buffer-callback: allow getting underlying iio_dev

2016-08-21T10:47:19+00:00

Add iio_channel_cb_get_iio_dev function to allow getting the underlying iio_dev. This is useful for setting the trigger of the consumer ADC device. Signed-off-by: Matt Ranostay Signed-off-by: Jonathan Cameron

iio: core: Add devm_ APIs for iio_channel_{get,release}_all

2016-04-19T18:58:15+00:00

Some of kernel driver uses the IIO framework to get the sensor value via ADC or IIO HW driver. The client driver get iio channel by iio_channel_get_all() and release it by calling iio_channel_release_all(). Add resource managed version (devm_*) of these APIs so that if client calls the devm_iio_channel_get_all() then it need not to release it explicitly, it can be done by managed device framework when driver get un-binded. This reduces the code in error path and also need of .remove callback in some cases. Signed-off-by: Laxman Dewangan Signed-off-by: Jonathan Cameron
