Jonathan writes: First set of new device support, features and cleanups for IIO in the 4.13 cycle Two entirely new drivers in here plus the usual range of cleanups and features. New device support * ad5064 - add ltc2631, ltc2633 and ltc2635 support. * bma180 - trivial support for bma250e (new id) * hid-sensor-rotation - add relative orientation and geometric orientation support. * isl29028 - add isl29030 support (its effectively the same part from a driver point of view) * maxim_thermocouple - add max31856 id. * meson-saradc - add meson8b SoC adc support. * ti-adc084s021 - new driver and bindings. * ti-adc108s102 - new driver and bindings. Staging graduations * isl29028 Features * bma180 - ACPI enumeration for BMA250E which is used in various x86 tablets. * hi8453 - add raw access rather than only events. * hid-sensor-hub - Implement batch mode in which we can set a threshold on the amount of time between data coming from the fifos. This is the first device to do this rather than use a watershed on the number of samples. * hts221 - power management support * lsm6dsx - add system power management support. * rpr0521 - sampling frequency read / write * stm32-trigger - add support for TRG02 triggers. * tsl2583 - runtime power management support. Cleanups * core - inkern: fix a double unlock in iio_read_available_channel_raw when raw value doesn't appear to be raw (error path). - fixup accidental sizeof pointer in iio_device_add_mask_type. * docs - fix an accidental duplicated line in sysfs-bus-iio-meas-spec. * tools - use local include/uapi headers to ensure always up to date. - increase length of allowed trigger names. * ad9834 - symbolic to octal permissions. * ade7753 - symbolic to octal permissions. - fix indentation * ade7754 - symbolic to octal permissions. * ade7758 - symbolic to octal permissions. - ade7854 - symbolic to octal permissions. * as3935 - move out of storm check to given consistent results for raw and processed values. * bmp280 - fix bme280 naming in Kconfig help. * hi8435 - avoid garbage on event after enable. - add missing in_voltage_sensing_mode_available to list possible enum options. - handle the reset gpio with the obvious polarity rather than relying on DT to provide it correctly. * hid-sensors - fix a wrong error path scrubbing of return values. * hid-sensors-accel - drop static on a local variable * hid-sensors-rotation - Add missing scale and offset property parsing support. * ina2xx - Fix a bad use of GENMASK and some typos and whitespace issues. * isl29018 - only declare the ACPI table when ACPI is enabled. * isl29028 - fix proximity sleep times. * lsm6dsx - replace ifdef CONFIG_PM with __maybe_unused to avoid the complexity of dealing with the various PM config variables. * meson-saradc - mark meson_sar_adc_data static and const. * rcar-gyroadc - derive the interface clock speed from the fck clock on the basis they are the same actual clock. - drop the now unused if clock from the bindings. * rpr0521 - disable sensor when marked as such rather than always enabling it. - poweroff if probe fails and we can talk to device. - make sure device powered off when it doesn't need to be on. - use sizeof rather than hardcoded size on value read. - whitespace fixup. - reorder channel numbers ready for buffered support which didn't quite make this pull request. * st-accel - fix platform data initialization to allow remove and reprobe. * st-pressure - fix platform data initialization to allow remove and reprobe. * tsl2x7x - S_IRUGO, S_IWUSR to octal values - rename driver for consistency with more recent drivers - drop FSF mailing address - replace DEVICE_ATTR macros with the shorter DEVICE_ATTR_RW form and relevant function renames. * zpa2326 - report an error for consistency with other error paths.

iio: adc: Add support for TI ADC108S102 and ADC128S102

2017-05-21T14:11:14Z

This is an upstream port of an IIO driver for the TI ADC108S102 and ADC128S102. The former can be found on the Intel Galileo Gen2 and the Siemens SIMATIC IOT2000. For those boards, ACPI-based enumeration is included. Due to the lack of regulators under ACPI, we hard-code the voltage provided to the VA pin of the ADC to 5 V, the value used on Galileo and IOT2000. For DT usage, the regulator "vref-supply" provides this information. Note that DT usage has not been tested.

Pull staging/IIO updates from Greg KH: "Here is the big staging tree update for 4.12-rc1. It's a big one, adding about 350k new lines of crap^Wcode, mostly all in a big dump of media drivers from Intel. But there's other new drivers in here as well, yet-another-wifi driver, new IIO drivers, and a new crypto accelerator. We also deleted a bunch of stuff, mostly in patch cleanups, but also the Android ION code has shrunk a lot, and the Android low memory killer driver was finally deleted, much to the celebration of the -mm developers. All of these have been in linux-next with a few build issues that will show up when you merge to your tree" Merge conflicts in the new rtl8723bs driver (due to the wifi changes this merge window) handled as per linux-next, courtesy of Stephen Rothwell. * tag 'staging-4.12-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging: (1182 commits) staging: fsl-mc/dpio: add cpu <--> LE conversion for dpaa2_fd staging: ks7010: remove line continuations in quoted strings staging: vt6656: use tabs instead of spaces staging: android: ion: Fix unnecessary initialization of static variable staging: media: atomisp: fix range checking on clk_num staging: media: atomisp: fix misspelled word in comment staging: media: atomisp: kmap() can't fail staging: atomisp: remove #ifdef for runtime PM functions staging: atomisp: satm include directory is gone atomisp: remove some more unused files atomisp: remove hmm_load/store/clear indirections atomisp: kill off mmgr_free atomisp: clean up the hmm init/cleanup indirections atomisp: handle allocation calls before init in the hmm layer staging: fsl-dpaa2/eth: Add maintainer for Ethernet driver staging: fsl-dpaa2/eth: Add TODO file staging: fsl-dpaa2/eth: Add trace points staging: fsl-dpaa2/eth: Add driver specific stats staging: fsl-dpaa2/eth: Add ethtool support staging: fsl-dpaa2/eth: Add Freescale DPAA2 Ethernet driver ...

iio: adc: add support for X-Powers AXP20X and AXP22X PMICs ADCs

2017-04-27T08:25:07Z

The X-Powers AXP20X and AXP22X PMICs have multiple ADCs. They expose the battery voltage, battery charge and discharge currents, AC-in and VBUS voltages and currents, 2 GPIOs muxable in ADC mode and PMIC temperature. This adds support for most of AXP20X and AXP22X ADCs. Signed-off-by: Quentin Schulz Acked-by: Maxime Ripard Acked-by: Chen-Yu Tsai Reviewed-by: Jonathan Cameron Signed-off-by: Lee Jones

iio: adc: add max1117/max1118/max1119 ADC driver

2017-04-14T14:09:06Z

This adds max1117/max1118/max1119 8-bit, dual-channel ADC driver. This new driver uses the zero length spi_transfers with the cs_change flag set and/or the non-zero delay_usecs. 1. The zero length transfer with the spi_transfer.cs_change set is required in order to select CH1. The chip select line must be brought high and low again without transfer. 2. The zero length transfer with the spi_transfer.delay_usecs > 0 is required for waiting the conversion to be complete. The conversion begins with the falling edge of the chip select. During the conversion process, SCLK is ignored. These two usages are unusual. But the spi controller drivers that use a default implementation of transfer_one_message() are likely to work. (I've tested this adc driver with spi-omap2-mcspi and spi-xilinx) On the other hand, some spi controller drivers that have their own transfer_one_message() may not work. But at least for the zero length transfer with delay_usecs > 0, I'm proposing a new testcase for the spi-loopback-test that can test whether the delay_usecs setting has taken effect.

iio: adc: add a driver for Qualcomm PM8xxx HK/XOADC

2017-04-08T16:42:26Z

The Qualcomm PM8xxx PMICs contain a simpler ADC than its successors (already in the kernel as qcom-spmi-vadc.c): the HK/XO ADC (Housekeeping/Chrystal oscillator ADC). As far as I can understand this is equal to the PMICs using SSBI transport and encompass PM8018, PM8038, PM8058, and PM8921, so this is shortly named PM8xxx. This ADC monitors a bunch of on-board voltages and the die temperature of the PMIC itself, but it can also be routed to convert a few external MPPs (multi-purpose pins). On the APQ8060 DragonBoard this feature is used to let this ADC convert an analog ALS (Ambient Light Sensor) voltage signal from a Capella CM3605 ALS into a LUX value. Developed and tested with APQ8060 DragonBoard based on Ivan's driver and Rama Krishna's patches. The SPMI VADC driver is quite different, but share enough minor functionality that I have split out to the common file in a previous patch.

iio: adc: break out common code from SPMI VADC

2017-04-08T16:40:49Z

The SPMI VADC and the earlier XOADC share a subset of common code, so to be able to use the same code in both drivers, we break out a separate file with the common code, prefix exported functions that are no longer static with qcom_* and bake an object qcom-spmi-vadc.o that contains both files: qcom-vadc-common.o and qcom-spmi-vadc-core.o. As we need to follow the procedure for making a kernel module or compiled in object from several files, but still want to produce the same module name, rename the qcom-spmi-vadc.c file to qcom-spmi-vadc-core.c so we can bake the two objects into qcom-spmi-vadc.o Cc: linux-arm-kernel@lists.infradead.org Cc: linux-arm-msm@vger.kernel.org Cc: Ivan T.
