Jonathan writes: Second set of IIO device support, features, cleanups and minor fixes for 5.3. A few bits for the counters subsystem mixed in here as well. There are some late breaking fixes as well, which aren't so urgent they can't wait for the merge window. New Device Support * adf4371 - New driver + bindings. - Support the adf4372 PLL. Mostly ID and bindings. * ad8366 (note includes rework of driver needed to allow support for these). - Support the ADL5240 variable gain amplifier (VGA). - Support the ADA4961 digital gain amplifier (DGA). * dps310 - New driver, in several parts from different authors for this temp and pressure sensor. - Includes errata workaround for a temperature reading issue. * stk3310 - Support the stk3335, mostly ID. Features and cleanups * core - drop error handling on debugfs registration. - harden by making sure we don't overrun iio_chan_info_postfix. * docs - convert remaining docs to rst. At somepoint we'll fit these few into the main IIO docs. - improve sampling_frequency_available docs but explaining the range form. * ad_sigma_delta - Drop a pointless goto. * ad2s1210 - Drop pointless platform data null check seeing as we don't actually use platform data anymore. * ad7124 - Relax limitation on channel numbers to allow pseudo different channels. - Support control of whether the input is buffered via DT. - Use dynamic allocation for channel configuration to make it easier to support new devices. - YAML binding conversion. * ad7150 - Comment tidy up. - Consistent and simple if (ret) handling of i2c errors. - FIELD_GET and GENMASK. - Ternary rather than !!(condition) for readability. - Use macros to avoid repetition of channel definitions. * ad7606 - Add software channel config (rather that pin controlled) - Refactor to simplify addition of new part in future. * ad7746 - of_deivce_id table. * ad7780 - MAINTAINERS entry - YAML DT bindings. * ad8366 - Stop using core mlock in favour of well scoped local lock. - SPDX + copyright date update. * ad9834 - of_device_id table * adf4371 - Add support for output stage muting before lock on has occured. * adis library - MAINTAINERS entry to reflect that this now Alexandru's problem ;) * adis162xx: - Fix a slightly incorrect set of comments and print statements on minimum supported voltage. * adis16203 - of_device_id table. * adis16240 - Add of_device_id table (in two parts as first patch only used it for MODULE_DEVICE_TABLE.) * adt7316-spi - of_device_id table * adxl372 - YAML DT binding conversion. - Cleanup use of buffer callback functions (precursor to core rework). * bh1710 - Simplify getting the i2c adapter from the client. * dht11 - Mote to newer GPIO consumer interface. * kxcjk-1013.c - Add binding for sensor in display of some ultrabooks after userspace tools updated for it not be a problem to report two similar sensors. * imx7d - drop unused variables. - white space - define instead of variable for clock frequency that is fixed. - drop pointless error message. * messon_saradc - SPDX * sps30 - MAINTAINERS entry - YAML binding conversion. * st_accel - Tidy up ordering in various buffer related callbacks. This is part of a long running effort to simplify the core code. * stm32-dfsdm: - Manage the resolution cleanly in triggerd modes. - Add fast mode support which allows more flexible filter choices. - Add a comment on the reason for a 16 bit record when technically not 'required'. * st_lsm6dsx - Embed device name in the sensor_settings struct as i3c doesn't have a convenient name field to use for this. * xilinx-adc - Relax constraints on supported platforms to reflect that this can used with FPGAs on PCIe cards and hence many architectures. * counters/ftm-quaddec - Fix some formatting io MODULE_AUTHOR - MAINTAINERS entry Fixes * tools - fix incorrect handling of 32 bit channels. * sca3000 - Potential endian bug that is unlikely to bite anyone (be64 host seems unlikely for this old part). * stm32-adc - Add vdda-supply. On some boards it needs to be turned on to supply the ADC. DT bindings included. * stm32-dfsdm - Fix output resolution to work with filter orders other than 3. - Fix output datatype as it's signed and previously claimed not to be. * tag 'iio-for-5.3b' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio: (68 commits) iio: iio-utils: Fix possible incorrect mask calculation iio: frequency: adf4371: Add support for output stage mute dt-bindings: iio: frequency: Add ADF4372 PLL documentation iio: frequency: adf4371: Add support for ADF4372 PLL dt-bindings: iio: adc: Add buffered input property Convert AD7124 bindings documentation to YAML format. iio: adc: ad7124: Shift to dynamic allocation for channel configuration iio: adc: ad7124: Add buffered input support iio: adc: ad7124: Remove input number limitation MAINTAINERS: add ADIS IMU driver library entry iio: adis162xx: fix low-power docs & reports counter/ftm-quaddec: Add missing '>' in MODULE_AUTHOR iio: core: no need to check return value of debugfs_create functions docs: iio: convert to ReST iio: adc: stm32-adc: add missing vdda-supply dt-bindings: iio: adc: stm32: add missing vdda supply iio: adc: stm32-dfsdm: add comment for 16 bits record iio: adc: stm32-dfsdm: add fast mode support iio: adc: stm32-dfsdm: manage data resolution in trigger mode iio: adc: stm32-dfsdm: fix data type ...

docs: iio: convert to ReST

Merge tag 'staging-5.2-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging

2019-05-07T20:31:29+00:00

Pull staging / IIO driver updates from Greg KH: "Here is the big staging and iio driver update for 5.2-rc1. Lots of tiny fixes all over the staging and IIO driver trees here, along with some new IIO drivers. The "counter" subsystem was added in here as well, as it is needed by the IIO drivers and subsystem. Also we ended up deleting two drivers, making this pull request remove a few hundred thousand lines of code, always a nice thing to see. Both of the drivers removed have been replaced with "real" drivers in their various subsystem directories, and they will be coming to you from those locations during this merge window. There are some core vt/selection changes in here, that was due to some cleanups needed for the speakup fixes. Those have all been acked by the various subsystem maintainers (i.e. me), so those are ok. We also added a few new drivers, for some odd hardware, giving new developers plenty to work on with basic coding style cleanups to come in the near future. Other than that, nothing unusual here. All of these have been in linux-next for a while with no reported issues, other than an odd gcc warning for one of the new drivers that should be fixed up soon" [ I fixed up the warning myself - Linus ] * tag 'staging-5.2-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging: (663 commits) staging: kpc2000: kpc_spi: Fix build error for {read,write}q Staging: rtl8192e: Remove extra space before break statement Staging: rtl8192u: ieee80211: Fix if-else indentation warning Staging: rtl8192u: ieee80211: Fix indentation errors by removing extra spaces staging: most: cdev: fix chrdev_region leak in mod_exit staging: wlan-ng: Fix improper SPDX comment style staging: rtl8192u: ieee80211: Resolve ERROR reported by checkpatch staging: vc04_services: bcm2835-camera: Compress two lines into one line staging: rtl8723bs: core: Use !x in place of NULL comparison. staging: rtl8723bs: core: Prefer using the BIT Macro. staging: fieldbus: anybus-s: fix wait_for_completion_timeout return handling staging: kpc2000: fix up build problems with readq() staging: rtlwifi: move remaining phydm .h files staging: rtlwifi: strip down phydm .h files staging: rtlwifi: delete the staging driver staging: fieldbus: anybus-s: rename bus id field to avoid confusion staging: fieldbus: anybus-s: keep device bus id in bus endianness Staging: sm750fb: Change *array into *const array staging: rtl8192u: ieee80211: Fix spelling mistake staging: rtl8192u: ieee80211: Replace bit shifting with BIT macro ...

iio: afe: rescale: new driver

2018-04-28T17:03:22+00:00

If an ADC channel measures the midpoint of a voltage divider, the interesting voltage is often the voltage over the full resistance. E.g. if the full voltage is too big for the ADC to handle. Likewise, if an ADC channel measures the voltage across a shunt resistor, with or without amplification, the interesting value is often the current through the resistor. This driver solves these problems by allowing to linearly scale a channel and/or by allowing changes to the type of the channel. Signed-off-by: Peter Rosin Signed-off-by: Jonathan Cameron

iio: multiplexer: new iio category and iio-mux driver

2017-06-03T10:29:26+00:00

When a multiplexer changes how an iio device behaves (for example by feeding different signals to an ADC), this driver can be used to create one virtual iio channel for each multiplexer state. Depends on the generic multiplexer subsystem. Cache any ext_info values from the parent iio channel, creating a private copy of the ext_info attributes for each multiplexer state/channel.
