iio: core: remove extra semi-colon from devm_iio_device_register() macro

2020-04-29T14:31:24Z

commit a07479147be03d2450376ebaff9ea1a0682f25d6 upstream. This change removes the semi-colon from the devm_iio_device_register() macro which seems to have been added by accident.

iio: ad_sigma_delta: Properly handle SPI bus locking vs CS assertion

2019-05-31T13:46:24Z

[ Upstream commit df1d80aee963480c5c2938c64ec0ac3e4a0df2e0 ] For devices from the SigmaDelta family we need to keep CS low when doing a conversion, since the device will use the MISO line as a interrupt to indicate that the conversion is complete. This is why the driver locks the SPI bus and when the SPI bus is locked keeps as long as a conversion is going on. The current implementation gets one small detail wrong though. CS is only de-asserted after the SPI bus is unlocked. This means it is possible for a different SPI device on the same bus to send a message which would be wrongfully be addressed to the SigmaDelta device as well. Make sure that the last SPI transfer that is done while holding the SPI bus lock de-asserts the CS signal.

Pull staging/IIO updates from Greg KH: "Here is the big staging and IIO driver update for 4.18-rc1. It was delayed as I wanted to make sure the final driver deletions did not cause any major merge issues, and all now looks good. There are a lot of patches here, just over 1000. The diffstat summary shows the major changes here: 1007 files changed, 16828 insertions(+), 227770 deletions(-) Because of this, we might be close to shrinking the overall kernel source code size for two releases in a row. There was loads of work in this release cycle, primarily: - tons of ks7010 driver cleanups - lots of mt7621 driver fixes and cleanups - most driver cleanups - wilc1000 fixes and cleanups - lots and lots of IIO driver cleanups and new additions - debugfs cleanups for all staging drivers - lots of other staging driver cleanups and fixes, the shortlog has the full details. but the big user-visable things here are the removal of 3 chunks of code: - ncpfs and ipx were removed on schedule, no one has cared about this code since it moved to staging last year, and if it needs to come back, it can be reverted. - lustre file system is removed. I've ranted at the lustre developers about once a year for the past 5 years, with no real forward progress at all to clean things up and get the code into the "real" part of the kernel. Given that the lustre developers continue to work on an external tree and try to port those changes to the in-kernel tree every once in a while, this whole thing really really is not working out at all. So I'm deleting it so that the developers can spend the time working in their out-of-tree location and get things cleaned up properly to get merged into the tree correctly at a later date. Because of these file removals, you will have merge issues on some of these files (2 in the ipx code, 1 in the ncpfs code, and 1 in the atomisp driver). Just delete those files, it's a simple merge :) All of this has been in linux-next for a while with no reported problems" * tag 'staging-4.18-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging: (1011 commits) staging: ipx: delete it from the tree ncpfs: remove uapi .h files ncpfs: remove Documentation ncpfs: remove compat functionality staging: ncpfs: delete it staging: lustre: delete the filesystem from the tree. staging: vc04_services: no need to save the log debufs dentries staging: vc04_services: vchiq_debugfs_log_entry can be a void * staging: vc04_services: remove struct vchiq_debugfs_info staging: vc04_services: move client dbg directory into static variable staging: vc04_services: remove odd vchiq_debugfs_top() wrapper staging: vc04_services: no need to check debugfs return values staging: mt7621-gpio: reorder includes alphabetically staging: mt7621-gpio: change gc_map to don't use pointers staging: mt7621-gpio: use GPIOF_DIR_OUT and GPIOF_DIR_IN macros instead of custom values staging: mt7621-gpio: change 'to_mediatek_gpio' to make just a one line return staging: mt7621-gpio: dt-bindings: update documentation for #interrupt-cells property staging: mt7621-gpio: update #interrupt-cells for the gpio node staging: mt7621-gpio: dt-bindings: complete documentation for the gpio staging: mt7621-dts: add missing properties to gpio node ...

iio: adc: stm32-dfsdm: include stm32-dfsdm-adc.h

Fix the following sparse warnings: CHECK drivers/iio/adc/stm32-dfsdm-adc.c symbol 'stm32_dfsdm_get_buff_cb' was not declared. Should it be static? symbol 'stm32_dfsdm_release_buff_cb' was not declared. Should it be static? BTW, move interrupt.h to sort headers alphabetically.

iio:buffer: make length types match kfifo types

2018-03-30T10:14:32Z

Currently, we use int for buffer length and bytes_per_datum. However, kfifo uses unsigned int for length and size_t for element size. We need to make sure these matches or we will have bugs related to overflow (in the range between INT_MAX and UINT_MAX for length, for example). In addition, set_bytes_per_datum uses size_t while bytes_per_datum is an int, which would cause bugs for large values of bytes_per_datum. Change buffer length to use unsigned int and bytes_per_datum to use size_t. Signed-off-by: Martin Kelly Cc: Signed-off-by: Jonathan Cameron

iio: adc: ad7780: remove IIO_CHAN_INFO_SAMP_FREQ support

2018-03-17T20:50:26Z

The `ad7780` driver does not implement setting/getting the sampling frequency. For the ad7780/ad7781 devices, the control is done via an external pin, and the ad7170/ad7171 devices have a fixed sampling rate (so, no control). For these devices, and similar other that may be added later on, a AD_SD_CHANNEL_NO_SAMPLE_FREQ() macro has been added, which doesn't set the IIO_CHAN_INFO_SAMP_FREQ flag.

Pull staging/IIO updates from Greg KH: "Here is the big Staging and IIO driver patches for 4.16-rc1. There is the normal amount of new IIO drivers added, like all releases. The networking IPX and the ncpfs filesystem are moved into the staging tree, as they are on their way out of the kernel due to lack of use anymore. The visorbus subsystem finall has started moving out of the staging tree to the "real" part of the kernel, and the most and fsl-mc codebases are almost ready to move out, that will probably happen for 4.17-rc1 if all goes well. Other than that, there is a bunch of license header cleanups in the tree, along with the normal amount of coding style churn that we all know and love for this codebase. I also got frustrated at the Meltdown/Spectre mess and took it out on the dgnc tty driver, deleting huge chunks of it that were never even being used. Full details of everything is in the shortlog.
