Commit 4ae03019 ("staging:iio:dummy: Register same channels for device and buffer") has changed the number of parameters for iio_simple_dummy_configure_buffer() only for the IIO_SIMPLE_DUMMY_BUFFER case. Fix this by also changing the placeholder function declared in the header when buffering is not enabled. Signed-off-by:

The calculations for temperature and pressure compensation were already slightly optimized in comparison to the datasheet. So, it makes sense to optimize even a bit more, making proper use of C operators: - variable t in bmp280_compensate_temp() can be eliminated by directly returning the result of the relevant equation. - make use of the += operator and eliminate an unnecessary parenthesis level in bmp280_compensate_press(). When the initialization of the ctrl_meas register fails, the error message will now mention the right register name. During probe, i2c_set_clientdata() is called, although it is not necessary. Drop it. Signed-off-by: -

Minimal implementation for KMX61 6-axis accelerometer/magnetometer. It exports raw accel/magn readings together with scale and sampling frequency.

We already do have the length field in the struct iio_buffer which is expected to be in sync with the current size of the buffer. And currently all implementations of the get_length callback either return this field or a constant number. This patch removes the get_length callback and replaces all occurrences in the IIO core with directly accessing the length field of the buffer. Signed-off-by:

If a buffer implementation does not implement the set_length() callback the length will be static and can not be changed by userspace. Mark the length attribute as a read only property in this case so userspace is aware of this rather than just silently accepting any length value. Signed-off-by:

All buffers want at least the length and the enable attribute. Move the creation of those attributes to the core instead of having to do this in each individual buffer implementation. This allows us to get rid of some boiler-plate code. Signed-off-by:

The next patch will introduce new dependencies in iio_buffer_alloc_sysfs() to functions which are currently defined after iio_buffer_alloc_sysfs(). To avoid forward declarations move both iio_buffer_alloc_sysfs() and iio_buffer_free_sysfs() after those function. This is split into two patches one moving the functions and one adding the dependencies to make review of the actual changes easier. Signed-off-by:

There haven't been any users of the get_bytes_per_datum() callback for a while. The core assumes that the number of bytes per datum can be calculated based on the enabled channels and the storage size of the channel and iio_compute_scan_bytes() is used to compute this number. So remove the callback. Signed-off-by:

Originally device and buffer registration were kept as separate operations in IIO to allow to register two distinct sets of channels for buffered and non-buffered operations. This has since already been further restricted and the channel set registered for the buffer needs to be a subset of the channel set registered for the device. Additionally the possibility to not have a raw (or processed) attribute for a channel which was registered for the device was added a while ago. This means it is possible to not register any device level attributes for a channel even if it is registered for the device. Also if a channel's scan_index is set to -1 and the channel is registered for the buffer it is ignored. So in summary it means it is possible to register the same channel array for both the device and the buffer yet still end up with distinctive sets of channels for both of them. This makes the argument for having to have to manually register the channels for both the device and the buffer invalid. Considering that the vast majority of all drivers want to register the same set of channels for both the buffer and the device it makes sense to move the buffer registration into the core to avoid some boiler-plate code in the device driver setup path.
