2016-10-23iio: dac: mcp4725: support voltage reference selectionTomas Novotny
MCP47x6 chip supports selection of a voltage reference (VDD, VREF buffered or unbuffered). MCP4725 doesn't have this feature thus the eventual setting is ignored and user is warned. The setting is stored only in the volatile memory of the chip. You need to manually store it to the EEPROM of the chip via 'store_eeprom' sysfs entry.

Use a standard framework to get the reference voltage. It is done that way in the iio subsystem and it will simplify extending of the driver. Structure mcp4725_platform_data is left undeleted because it used in the next patch. This change breaks the current users of the driver, but there is no mainline user of struct mcp4725_platform_data.

2016-10-23iio: ms65611_core: Fixes dereferencing regulator pointerCrt Mori
Change in handling of the regulator description means that static checkers correctly assume we could be using dereferenced pointer to the regulator. In reality we will never get the -ENODEV error, as current behavior flow does not predict it, because: If the device tree or board file does not define suitable regulators for the component, it will be substituted by a dummy regulator, or, if regulators are disabled altogether, by stubs.

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: 104-quad-8: Add IIO support for the ACCES 104-QUAD-8William Breathitt Gray
The ACCES 104-QUAD-8 is a general purpose quadrature encoder counter/interface board. The 104-QUAD-8 is capable of monitoring the outputs of eight encoders via four on-board LSI/CSI LS7266R1 24-bit dual-axis quadrature counter chips. Core functions handled by the LS7266R1, such as direction and total count, are available. Performing a write to a counter's IIO_CHAN_INFO_RAW sets the counter and also clears the counter's respective error flag. Although the counters have a 25-bit range, only the lower 24 bits may be set, either directly or via a counter's preset attribute. Interrupts are not supported by this driver. This driver adds IIO support for the ACCES 104-QUAD-8 and ACCES 104-QUAD-4. The base port addresses for the devices may be configured via the base array module parameter.

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).

2016-09-18iio: accel: kxsd9: Deploy system and runtime PMLinus Walleij
This deploys runtime and system PM in the KXSD9 driver: - Use the force_runtime_suspend/resume callbacks as system PM operations. - Add buffer prepare/unprepare callbacks to grab the runtime PM while we're using buffered reads and put get/put_autosuspend in these. - Insert get/put_autosuspend calls anywhere the IO is used from the raw read/write callbacks. - Move the fullscale setting to be cached in the state container so we can restore it properly when coming back from system/runtime suspend. - Set the autosuspend delay to two orders of magnitude that of the sensor start-up time (20ms) so we will autosuspend after 2s. - Register the callbacks in both the SPI and I2C subdrivers. Tested with the I2C KXSD9 on the Qualcomm APQ8060 Dragonboard. Signed-off-by: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
2016-09-18iio: accel: kxsd9: Replace "parent" with "dev"Linus Walleij
What is passed to the .probe() and .remove() functions is technically the parent of the created IIO device but it becomes a big confusion for the head to have it named like this since it is usually clear from context the "dev" refers to the physical device, and when next adding PM callbacks a clean "struct device *dev" pointer is passed to these and that makes it even more confused. Rename "parent" to "dev" like in most other drivers. Signed-off-by: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
2016-09-18iio: accel: kxsd9: Fetch and handle regulatorsLinus Walleij
This adds supply regulator handling for the VDD and IOVDD inputs on the KXSD9 component, makes sure to bring the regulators online during probe and disable them on remove or the errorpath. Signed-off-by: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
2016-09-18iio: accel: kxsd9: Deploy proper register bit definesLinus Walleij
There are some hardcoded register values etc in the code, define proper bitfield definitions, and use them when getting and setting the scale. Optimize a read/modify/write to use regmap_update_bits() at the same time.
