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

iio: inkern: add iio_read_channel_average_raw

2014-03-16T18:00:33+00:00

Add iio_read_channel_average_raw to support reading averaged raw values in consumer drivers. Signed-off-by: Sebastian Reichel Signed-off-by: Jonathan Cameron

iio: iio_push_to_buffers(): Change type of 'data' to const void *

2013-09-15T18:02:07+00:00

Change the type of the 'data' parameter for iio_push_to_buffers() from 'u8 *' to 'const void *'. Drivers typically use the correct type (e.g. __be16 *) for their data buffer. When passing the buffer to iio_push_to_buffers() it needs to be cast to 'u8 *' for the compiler to not complain (and also having to add __force if we want to keep sparse happy as well). Since the buffer implementation should not care about the data layout (except the size of one sample) using a void pointer is the correct thing to do. Also make it const as the buffer implementations are not supposed to modify it. Signed-off-by: Lars-Peter Clausen Signed-off-by: Jonathan Cameron

iio: Update iio_channel_get API to use consumer device pointer as argument

2013-02-06T19:23:52+00:00

For iio_channel_get to work with OF based configurations, it needs the consumer device pointer instead of the consumer device name as argument. Signed-off-by: Guenter Roeck Acked-by: Anton Vorontsov Acked-by: Chanwoo Choi Signed-off-by: Jonathan Cameron

iio: Update iio_channel_get_all and iio_channel_get_all_cb API

2013-02-02T11:58:46+00:00

Pass device pointer instead of device name as parameter to iio_channel_get_all and iio_channel_get_all_cb. This will enable us to use OF information to retrieve consumer channel information. Signed-off-by: Guenter Roeck Signed-off-by: Jonathan Cameron
