Merge tag 'iio-for-3.8e' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next From Jonathan: "Fifth round of new IIO drivers, cleanups and fixes for the 3.8 cycle. Here we have a number of minor fixes. * a quirk for the hid sensor driver should be a boolean option. * return an error for a failed memdup in the hid sensor driver. * Fix a return value in adt7410. * A double free in the IIO event infrastructure. * Disabling interrupts in tsl2563 was wrong (never been correct!) * Incorrect signature for the iio_buffer_register stub * Incorrect return for isl29018 write_raw callback. * A number of minor fixes as part of the various rework series. New drivers and major rework. * Introduce and use extensively an adis library for numerous spi Analog Devices mems sensors. This then moves out of staging. * Lots of new stuff then added to this library to support newer sensors. * New drivers for ADIS16136 and ADIS16480 and similar. * Core support for barometric pressure sensors. * ad7298 cleanup and move out of staging. The bulk of this is from Lars-Peter Clausen. He's been rather busy!"

These buffers are a little interesting in that their content may have variable endianness, but all but one element will definitely be big endian. Reported-by:

Some of the newer generation devices from the ADIS16XXX series have more registers than what can be supported with the current register addressing scheme. These devices implement register paging to support a larger register range. Each page is 128 registers large and the currently active page can be selected via register 0x00 in each page. This patch implements transparent paging inside the common adis library. The register read/write interface stays the same and when a register is accessed the library automatically switches to the correct page if it is not already selected. The page number is encoded in the upper bits of the register number, e.g. register 0x5 of page 1 is 0x85. Signed-off-by:

The driver does not expose any custom API to userspace and none of the standard static code checker tools report any issues, so move it out of staging. Signed-off-by:

The recent cleanups have decimated the drivers code size by quite a bit. It is only a few hundred lines in total now. Putting everything into one file also allows to reduce the code size a bit more by removing a few lines of boilerplate code. The only functional change made by this patch is that we now always include buffer support, instead of making it optional. This is more consistent with what we do for other drivers. Signed-off-by:

The temperature scale and offset depend on the reference voltage, the current formula used in the driver assumes a 2.5V reference. This patch modifies the code to report the unprocessed value for the temperature channel "raw" property and to provide proper "scale" and "offset" properties which depend on the selected reference voltage.

Rework the regulator handling of the driver to match more closely what we do in other drivers. Make the regulator non-optional if a external reference is used. Also dispose the option of specifying the reference voltage via platform data. Signed-off-by:

For buffered mode we do not want to perform endianness conversion in the kernel, but rather offload it to user space, since it is not always required to do a conversion at all. It also greatly simplifies the kernel code since no post-processing has to be done and may allow future optimizations like streaming data directly to a storage device or over the network via DMA.

Now that the adis library no longer depends on the sw_ring buffer implementation we can move it out of staging. While we are at it also sort the entries in the iio Kconfig and Makefile to be in alphabetical order. Signed-off-by:

Currently the driver reads out all sample registers of the device and throws away those which it does not need. Furthermore the SPI message is constructed each time the trigger handler is run, although it will be the same each time. This patch preallocates and pre-constructs the SPI message in the "update_scan_mode" callback. Only those register which are actually selected for sampling are included in the message. The patch also gets rid of the conversion of the sample data from big endian to the native endianness and instead marks the channel as big endian in its scan type. This allows to directly push the SPI transfer buffer to the IIO buffer without the need to post-process it. Signed-off-by:

Use the triggered buffer helper functions to setup and tear down the buffer for the adis library instead of doing this manually. This also means that we switch away from the deprecated sw_ring buffer and use the kfifo buffer now instead. Signed-off-by:
