git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next Jonathan writes: First round of IIO new device support, features and cleanups for the 4.10 cycle. Fair number of outreachy related patches in here. Some of these may well have already been picked up by Greg but git will sort that out for us. Also some good staging cleanup work from other sources. Thanks Brian and Lars in particular for this. New device support * ACCES 104-quad-8 - New driver for this 8 channel encoder input board. Lots of new ABI with this one. * AD7766 - New driver supporting AD7766, AD7766-1, AD7766-2, AD7767, AD7767-1 and AD7767-2 24 bit ADCs. * dmard 10 - New driver for this 3 axis accelerometer. * Honeywell ABP pressure sensors. - New driver covering 56 parts in this series (too many to list here!) * HTS221 - New driver to support this relative humidiy and temperature device. * LMP91000 - New driver for this potentiostat (form of chemical sensor). Nice example of use of the buffered consumer interfaces and the use of a consumer provided trigger. * MiraMEMS DA311 - New driver for this 3 axis accelerometer. * MiraMEMS DA280 - New driver for this 3 axis accelerometer. Follow up caught up with vendor prefixes for these. Staging graduations * isl29018 light sensor - Fixes and cleanups listed below (thanks for your hard work on this Brian!) * sca3000 - Fixes and cleanups listed below. This was one of the small set of drivers that went into staging when IIO was first added. Turns out it had a few bugs and needed to be brought into the modern era! Not clear if I am the only person who actually has one of these still wired to a board. New features (Core) - Add an iio_trigger_validate_own_device helper which relies on the device and trigger having the same parent. Convenient to have this for some of the more complex trigger / device interactions. Was hand rolled in a few drivers already so good to bring it into the core. - Add an iio_read_channel_offset in kernel access helper (similar to the existing one for scale). - IIO_ATTR_{RO, WO, RW} and IIO_DEVICE_ATTR_{RO, WO, RW} macros. These lead some rather contrived function naming, but there is no denying they do reduced boilerplate. I'm going to resist their introduction in drivers 'unless' they form part of a larger set of cleanups. - Counter channel type and index type. New features (Drivers) * hdc100x - Triggered buffer support. * mcp4725 - Device tree bindings and support. - Voltage reference selection. * ti-adc0832 - Triggered buffer support. * ti-adc161s626 - Add regulator support allowing _scale and _offset values to be established and exported. New features (Tools) * iio_generic_buffer - -A option to force enable all channels rather than faulting if some are already enabled (like -a does). Followup patches tidied this support up. Cleanups (Core) - Use kmalloc_array in iio_scan_mask_set. - Take event_attrs field of iio_info structure constant - Staging todo list updates. Most of it was long done. - MAINTAINERS had a wrong directory listing. Cleanups (Drivers) * Missing i2c trivial devices entries. * ad5592r - Fix an endian type related sparse warnings. * ad7150 - Constify the event attribute_group structures. * ad7152 - Add some blank lines to improve readability. - Sampling frequency control via chan-info element rather than hand rolled attributes. - add a new lock to avoid use of mlock for non state change related locking. * ad7280 - Constify atrribute_group structure (second patch covers the event ones) * ad7606 (Lars is driving most of the cleanup on this with some additions from Eva) - Fix improper setting of oversampling pins. This has been broken a very long time in this staging driver, so not going to push this back to stable. - Implement oversampling configuration via the chan_info mask element. - Remove an unused int_vref_mv field. - Remove a reundant name field from ad7606_chip_info. - Remove default device configuration from platform_data in favour of whatever the power on defaults are. - Remove out of band error reporting in the kernel log as not providing much information. - Fix oversampling ratio by having 1 be the value for no oversampling. - Avoid allocating buffer for each data capture. - Factor out common code between periodic and one-shot capture. - Move set_drvdat into common code. - Let the common probe function return int rather than jumping through an ERR_PTR. - Pass struct device * into common remove to simplify code. - Always run trigger handler only once per event (no one can remember why it was being possibly done twice). - Move over to the GPIO descriptor API to shorten and clarify code. - Move the buffer code into the main file as it's not optional and is now rather short in this driver. - Fix the naming of the supply regulator. - Rework regulator handling to handle errors including deferred probing. - Tidy up a ptr_err or 0 return. * ad7746 - Sampling frequency control via info_mask element rather than hand rolled * ad7758 - Sampling frequency control via info_mask element rather than hand rolled attributes. * ad7816 - Constify the event attribute_group structure. * adt7316 - Constify the event attribute group structures. * ak8974 - Cleanup some sparse warnings about endian types. * ak8975 - Cleanup some sparse warnings about endian types. * bmi160 - Spare endian warning cleanups. * isl29018 (towards staging graduation) - Remove unusedvariables and defines. - Improve consistency of error handling. - Signed / unsigned comparison fixes. - Use the IIO_DEVICE_ATTR_{RO, RW} macros - Fix a race in in_illuminance_scale_available_show. - Cleanup exit points of _read_raw - Sanity check if in suspended state during a write_raw call as was already done for read_raw. - Document device tree bidnings. - Document infrared supression controls. - Add some newlines to improve readability and drop one that shouldn't be there. - Fix a poorly named functions name. - Fix multiline coment syntax. - Tidy up a pair or return statements by unifying them. - Rename description in Kconfig for consistency with similar drivers. * lidar - cleanup power management by dropping unnecessary call. * ltr501 - Use the claim_direct_mode helpers. Fix a race condition along the way. * max1027 - Fix a dubious x | !y sparse warning. - Use the new iio_trigger_validate_own_device helper. * max440000 - Clean up some sparse warnings about endian types. * mcp4725 - Use the regulator framework to establish the reference voltage rather than getting it from platform data. - Tidy up a comment typo. - Fix a wrong PTR_ERR query (wrong regulator). * mma7660 - Take a mma7660_nscale static. * mma8452 - Use the new iio_trigger_validate_own_device helper. - Use claim_direct_mode helpers - fix a race condition along the way. * mpl3115 - Use claim_direct_mode helpers - fix a race condition along the way. * ms65611 - Tidy up regulator error handling and clean out a static warning in the mix. * sca3000 - Avoid a potential unitialized variable if a hardware read returns a value that isn't actually supported (mostly warning supression). - Fix a use before setting of the indio_dev->buffer pointer. Broken for a very long time so not going to rush this into stable. - Merge buffer file with core file. We used to always split these. Sometimes it's just not worth the hassle. In this case the device's main feature is it's hardware fifos so unlikely anyone would want to run it without. - Drop the sca3000_register_ring_funcs function as it's a pointless wrapper once we have only one file. - Fix cleaning of flag + setting of size of scan. Without this you can't start the buffer twice and expect sensible (or any) results. Again, broken for a long time so not heading for stable. - Drop the custom watershed setting ABI - for now we'll just support one value. - Move to a hybrid hard / soft buffer design (how we've been doing it for similar devices for a while now!) - Cleanup some unusued variables. - Use a fake channel to support core handling of freefall event registration. - Cleanup the register defines. - Fix an off by one error in axis due to IIO_NO_MOD taking up the 0 value. Been broken since first admission of IIO to the staging tree. - Add readback of the 3db low pass filter frequency and later writing allowing droppign of custom measurement mode attributes as they can be represented by the filter choices that is their main characteristic. - Drop non standard revision attr and replace with dev_info on probe. - Avoid a race in probe. - Various formatting fixes. - Kernel-docify docs that were very nearly in the write format. * tsl2583 - Constify attribute_group structure. * zpa2326 - Drop a redundant DEBUG ifdef. Cleanups (Tools) * iio_generic_buffer - Fix the ? arguement. Previously it sort of worked as you got the help message as a result of it not recognising the arguement.

git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging Pull staging and IIO updates from Greg KH: "Here is the big staging and IIO driver pull request for 4.9-rc1. There are a lot of patches in here, the majority due to the drivers/staging/greybus/ subsystem being merged in with full development history that went back a few years, in order to preserve the work that those developers did over time. Lots and lots of tiny cleanups happened in the tree as well, due to the Outreachy application process and lots of other developers showing up for the first time to clean code up. Along with those changes, we deleted a wireless driver, and added a raspberrypi driver (currently marked broken), and lots of new iio drivers. Overall the tree still shrunk with more lines removed than added, about 10 thousand lines removed in total. Full details are in the very long shortlog below. All of this has been in the linux-next tree with no issues. There will be some merge problems with other subsystem trees, but those are all minor problems and shouldn't be hard to work out when they happen (MAINTAINERS and some lustre build problems with the IB tree)" And furter from me asking for clarification about greybus: "Right now there is a phone from Motorola shipping with this code (a slightly older version, but the same tree), so even though Ara is not alive in the same form, the functionality is happening. We are working with the developers of that phone to merge the newer stuff in with their fork so they can use the upstream version in future versions of their phone product line. Toshiba has at least one chip shipping in their catalog that needs/uses this protocol over a Unipro link, and rumor has it that there might be more in the future. There are also other users of the greybus protocols, there is a talk next week at ELC that shows how it is being used across a network connection to control a device, and previous ELC talks have showed the protocol stack being used over USB to drive embedded Linux boards. I've also talked to some people who are starting to work to add a host controller driver to control arduinos as the greybus PHY protocols are very useful to control a serial/i2c/spio/whatever device across a random physical link, as it is a way to have a self-describing device be attached to a host without needing manual configuration. So yes, people are using it, and there is still the chance that it will show up in a phone/laptop/tablet/whatever from Google in the future as well, the tech isn't dead, even if the original large phone project happens to be" * tag 'staging-4.9-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging: (3703 commits) Staging: fbtft: Fix bug in fbtft-core staging: rtl8188eu: fix double unlock error in rtw_resume_process() staging:r8188eu: remove GEN_MLME_EXT_HANDLER macro staging:r8188eu: remove GEN_DRV_CMD_HANDLER macro staging:r8188eu: remove GEN_EVT_CODE macro staging:r8188eu: remove GEN_CMD_CODE macro staging:r8188eu: remove pkt_newalloc member of the recv_buf structure staging:r8188eu: remove rtw_handle_dualmac declaration staging:r8188eu: remove (RGTRY|BSSID)_(OFT|SZ) macros staging:r8188eu: change rtl8188e_process_phy_info function argument type Staging: fsl-mc: Remove blank lines Staging: fsl-mc: Fix unaligned * in block comments Staging: comedi: Align the * in block comments Staging : ks7010 : Fix block comments warninig Staging: vt6655: Remove explicit NULL comparison using Coccinelle staging: rtl8188eu: core: rtw_xmit: Use macros instead of constants staging: rtl8188eu: core: rtw_xmit: Move constant of the right side staging: dgnc: Fix lines longer than 80 characters Staging: dgnc: constify attribute_group structures Staging: most: hdm-dim2: constify attribute_group structures ...
2016-10-01iio: pressure: Add driver for Honeywell ABP familyMarcin Malagowski
This patch adds minimal driver for the Honeywell Amplified Basic Pressure sensors series. Sensors are pretty simple but are available in many variants: - psi/mbar/kPa output, - analog/i2c/spi, - gage/differential measurement, - different measure ranges etc. Refer to datasheets for more details: http://sensing.honeywell.com/honeywell-sensing-basic-board-mount-pressure-sensors-abp-series-datasheet-323005128-c-en.pdf http://sensing.honeywell.com/index.php%3Fci_id%3D45841 Driver internals: - i2c only. measure request is done by the SMBUS QUICK cmd, so if the i2c bus doesn't support it, it is required to send a dummy byte to trigger measurement, - since iio sysfs expects kilopascals, mbar-variants are treated as their respective kPa-s, hence i2c id-table has doubled entries in one line: { "abp060mg", ABP006KG }, { "abp006kg", ABP006KG }, - psi-variants have prescaled values in config, - no temperature reads yet. Work remained: - optional temperature channel, - SPI support, - DT binding. Changes since v1: - mutex is now locked in read_raw(), - corrected error codes, - fixed coding style issues, - renamed few defines and functions abp -> abp060mg (some structs left as they were to keep the sensible meaning).

2016-07-03iio: pressure: bmp280: add SPI interface driverLinus Walleij
This patch mimics the SPI functionality found in the misc driver in drivers/misc/bh085-spi.c to make it possible to reuse the existing BMP280/BMP180/BMP085 driver with all clients of the other driver. The adoption is straight-forward since like the other driver, it is a simple matter of using regmap. This driver is also so obviously inspired/copied from the old misc driver in drivers/misc/bmp085.c that I just took the liberty to add in the authors of the other drivers + self in the core driver file. The MISC driver also supports a variant named "BMP181" so include that here to be complete in comparison to the old driver. The bus mapping code for SPI was written by Akinobu Mita.

This creates a separate BMP280_I2C Kconfig entry that gets selected by BMP280 for I2C transport. As we currently only support I2C transport there is not much practical change other than getting a separate object file (or module) for the I2C driver part. The old Kconfig symbol BMP280 will still select the stuff we need so that oldconfig and old defconfigs works fine.

2013-08-03iio: Add a comment to about alphabetical order to Kconfigs and MakefilesLars-Peter Clausen
Keeping Makefile and Kconfig entries in alphabetical order usually works better than just appending new entries at the end, since it reduces the amount of conflicts. This patch adds a comment to the IIO Kconfig and Makefile files to document that the entries should be kept in alphabetical order. Also reorder those entries which weren't in alphabetical order yet.
