IIO_ST is going away as it is a pain to maintain. Note that this driver currently ensures all fields are converted to the native endianness to keep things consistent across the different bus types. Signed-off-by:

The IIO_ST macro no longer covers all the elements of struct scan_type and has this has lead to some bugs being introduced. The drivers are easier to follow with this structure being directly filled so that is now preferred. Signed-off-by:

Now that all drivers have been converted to the new event config interface we can remove for the legacy event config interface. Also drop the '_new' suffix for the event config interface callbacks, since those are the only callbacks now. Signed-off-by:

The mxs LRADC is able to read an internal die temperature sensor. The temperature has to be calculated from the value read on channel 8 and channel 9. To be able to expose the result to hwmon, implement iio channel 8 as (channel 9 - channel 8). Then, implement IIO_CHAN_INFO_SCALE and IIO_CHAN_INFO_OFFSET so that it can be processed by hwmon through the in kernel provider/consumer mechanism. Signed-off-by:

Currently the IIO buffer interface only allows non-blocking reads. This patch adds support for blocking IO. In blocking mode the thread will go to sleep if no data is available and will wait for the buffer implementation to signal that new data is available by waking up the buffers waitqueue. Signed-off-by:

This patch implements the data_available() callback for the kfifo buffer instead of using the stufftoread flag. The kfifo used by the buffer already knows whether it is empty or not based on the position of its read and write pointer. Using this makes it a lot easier to tell whether data is available or not and it is not necessary to take special measures to ensure that no race conditions between reading and writing from the buffer occur. Note, that we still have to take the buffers lock to protect against concurrent resizeing of the kfifo. Signed-off-by:

This patch adds a new data_available() callback to the iio_buffer_access_funcs struct. The callback is used to indicate whether data is available in the buffer for reading. It is meant to replace the stufftoread flag from the iio_buffer struct. The reasoning for this is that the buffer implementation usually can determine whether data is available rather easily based on its state, on the other hand it can be rather tricky to update the stufftoread flag in a race free way.
