git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next Jonathan writes: 2nd round of new IIO device support, features and cleanups for the 4.6 cycle. New Device Support * Apex stx104 DAC - new driver for this PC104 board. Right now DAC support only. * ADI ad5064 - Add support for ad5625, ad5627, ad5645, ad5665, ad5667 DACs. - Add support for Linear Technology ltc2606, ltc2607, ltc2609, ltc2616, ltc2617, ltc2619, ltc2626, ltc2627 and ltc2629. * ADI ad7192 - add support for the ad7193 * Invensense mpu6050 - substantial rework of driver to use regmap allowing SPI support extending the now split driver to cover the MPU6000. * TI adc0832 - new driver supporting ADC0831, ADC0832, ADC0834 and ADC0838 ADCs. * TI ads1015 - new driver, note that there is an existing hwmon driver. The long term intention is to probably remove the hwmon driver but for now we just have guards in place to ensure this driver is not built if that one is enabled. * TI afe4403 - new driver for this heart rate monitor / pulse oximeter front end chip. * TI afe4404 - new driver for this heart rate monitor / pulse oximeter front end chip. Staging Graduations * mxs-lradc - A combined general purpose and touch screen (input) device driver. Originally held in staging to allow reworking into and MFD but as that wasn't happening and isn't an absolute requirement we are moving it out of staging. Driver new features * ms5611 - triggered buffer support - IIO_CHAN_INFO_SCALE to aid the triggered buffer support. Driver cleanups / reworks / fixes * ad5064 - Use an enum for the register map layout to allow support of additional chips (precursor to the new support listed above). - Structural driver changes to allow support of the slightly different handling for the ltc parts above. * ad5933 - drop an exceptional & unnecessary for a function pointer. * ad7606 - Cleanup the repeated copies of pm ops. - consolidate the various channels specs via a sport of rearranging so only one version is needed. * atlas ph sensor - add select IRQ_WORK * hmc8543 (soon to move out of staging) - Comment style fixes - functionality of suspend and resume was swapped. * spear-adc - use devm_clk_dev instead of managing the clk lifetime by hand. Core * Use new dmaengine_terminate_sync call to avoid a theoretical race. * Fix docs for mlock in struct iio_dev as it is correctly taken in some drivers (docs used to say for core only). * Add a helper function for calculating the scan index storage size within the core cutting out some cut and paste versions of the same code.

git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next Jonathan writes: Second set of IIO new drivers, functionality and cleanups for the 4.5 cycle. The big one here is the configfs support which has been a long time in the works but should allow for cleaner ways to do instantiation of those elements of IIO that aren't directly connected to specific hardware. Lots of cool new stuff we can use this for in the works! New core stuff (basically all configfs support related) * Configfs support - Core support (was waiting for a configfs patch that went in around 4.4rc2) - A little fixlet to add a configfs.h to contain a reference to the configfs_subsystem structure. * Some infrastructure to simplify handling of software based triggers (i.e. ones with no actual hardware associated with them) * A high resolution timer based trigger. This has been around for years but until the configfs support was ready we didn't have a sensible way of instantiating instances of it (the method used for the sysfs_trigger has never been really satisfactory) New Device Support * AMS iAQ Volatile Organic Compounds sensor support. * Freescale imx7d ADC driver * Maxim MAX30100 oximeter driver (note that for these devices most of the smart stuff will be in userspace - effectively they are just light sensors with some interesting led synchronization as far as the kernel is concerned). * Microchip mcp3421 support added to the mcp3422 driver. * TI adc124s021 support added to the adc128s052 driver. * TI ina219, inda226 power monitors. Note that there is an existing hwmon driver for these parts, the usecase is somewhat different so it is unclear at this point if the hwmon driver will eventually be replaced by a bridge from this driver. In the meantime the Kconfig dependencies should prevent both from being built. New driver functionality * us8152d power management support. Cleanups, fixups * Use list_for_each_entry_safe instead of list_for_each_safe with the entry bit coded longhand. * Select IRQ_WORK for IIO_DUMMY_EVGEN. This is a fix that somehow got lost when the driver was moved so lets do it again. * st-accel - drop an unused define. * vz89x, lidar - optimize i2c transactions by using a single i2c tranfers instead of multiple calls where supported (fall back to smbus calls as before if not). * Use dev_get_platdata() in staging drivers: tsl2x7x, adcs and frequency drivers instead of direct access to the structure element.
2015-12-02staging:iio:mxs-lradc Fix large integer implicitly truncated to unsigned warningJonathan Cameron
The change to using BIT(20) for one of the bit shifts resulted in a constant becoming unsigned. When combined with the existing signed constants in a couple of places, this caused possible trouble, hence the warnings: drivers/staging/iio/adc/mxs-lradc.c: In function ‘mxs_lradc_complete_touch_event’: drivers/staging/iio/adc/mxs-lradc.c:325:5: warning: large integer implicitly truncated to unsigned type [-Woverflow] (((x) << LRADC_DELAY_TRIGGER_LRADCS_OFFSET) & \ ^ drivers/staging/iio/adc/mxs-lradc.c:734:7: note: in expansion of macro ‘LRADC_DELAY_TRIGGER’ LRADC_DELAY_TRIGGER(1 << TOUCHSCREEN_VCHANNEL1) | ^ LD [M] drivers/staging/iio/accel/adis16201.o drivers/staging/iio/adc/mxs-lradc.c: In function ‘mxs_lradc_buffer_preenable’: drivers/staging/iio/adc/mxs-lradc.c:322:42: warning: large integer implicitly truncated to unsigned type [-Woverflow] #define LRADC_DELAY_TRIGGER_LRADCS_MASK (0xff << 24) ^ drivers/staging/iio/adc/mxs-lradc.c:1308:29: note: in expansion of macro ‘LRADC_DELAY_TRIGGER_LRADCS_MASK’ mxs_lradc_reg_clear(lradc, LRADC_DELAY_TRIGGER_LRADCS_MASK | ^ drivers/staging/iio/adc/mxs-lradc.c: In function ‘mxs_lradc_buffer_postdisable’: drivers/staging/iio/adc/mxs-lradc.c:322:42: warning: large integer implicitly truncated to unsigned type [-Woverflow] #define LRADC_DELAY_TRIGGER_LRADCS_MASK (0xff << 24) ^ drivers/staging/iio/adc/mxs-lradc.c:1327:29: note: in expansion of macro ‘LRADC_DELAY_TRIGGER_LRADCS_MASK’ mxs_lradc_reg_clear(lradc, LRADC_DELAY_TRIGGER_LRADCS_MASK | The simplest fix is to force LRADC_DELAY_TRIGGER_LRADCS_MASK to be a shift of an unsigned 0xff rather than a signed one. This is ugly considering it is the only constant in the driver which is so forced, but it does deal with the issue.

git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next Jonathan writes: First set of new device support, features and cleanups for IIO in the 4.5 cycle Usual mixed bag, but the big item perhaps in this series is the DMA buffer support added by Lars-Peter Clausen. It's been in the works for a long time and it will be interesting to see what hardware support shows up now that this is available. New core features + associate cleanup. * Add generic DMA buffer infrastructure * Add a DMAengine framework based buffer Also associated minor changes. - Set the device buffer watermark based on the minimum watermark for all attached buffers rather than just the 'primary' one. - iio_buffer_init - only set the watermark default if one hasn't already been provided. This allows simple support for devices with a fixed watermark. - read only attribute for watermark on fixed watermark devices. - add explicit buffer enable/disable callbacks to allow the buffer to do more than trivial actions when it is being turned on and off. * IIO_VAL_INT support in write_raw_get_fmt function. New device support * Freescale MMA7455/7456L accelerometers * Memsic MXC6255XC accelerometer * ST lis2dh12 accelerometer * TI ADS8688 ADC * TI Palamas (twl6035/7) gpadc New driver features * mma8452 - support either of the available interrupt pins to cope with the case where board layout has lead to a particular one being connected. Staging graduation * Dummy driver - this driver acts as both an example and a test device for those with out hardware to develop userspace code against. Cleanups and minor bits and bobs. * treewide - Sort out the ordering of iio_device_register/unregister vs runtime pm function calls so that it's all nice and consistent and not race prone. - Check sscanf return values. None of the cases will actually happen as the strings are supplied internally, but best to be consistent on this. * ad7780 - switch over to the gpio descriptor interface and remove the now unused platform data which gets rid of a header entirely. * ad7793 - drop a pointless else statement. * at91_adc - Swap kmalloc_array in for a kmalloc doing the same job. * dummy - get rid of some commented out lines that snuck in during the move of the driver. * lm3533-als - Print an error message on provision of an invalid resistance. * mcp320x - Add compatible strings with vendor prefix and deprecate those with no vendor prefix. * mxs-lradc - Use BIT macro in various places rather than shifted ones. * pa12203001 - Power off the chip if the registration fails. * pulsedlight-lidar-lite - add runtime PM support. * xilinx XADC - constify an iio_buffer_setup_ops structure.
2015-11-25staging/ad7606: Actually build the interface modulesMichal Marek
The ad7606_par and ad7606_spi drivers are not built if CONFIG_AD7606=m, because kbuild does not currently support <objname>-m syntax. Even if we add kbuild support, ad7606 fails to link, because of duplicate module_init definitions. Make the two drivers separate modules, as the Kconfig help text already suggests. Also, CONFIG_IIO_BUFFER is a dependency of CONFIG_AD7606, so there is no need to test for it in the Makefile. Signed-off-by: Michal Marek <mmarek@suse.com>

Otherwise we report an error on all writes. - Fix a shift for ad5629 and ad5669 which gives incorrect DAC output on these parts. * ad7793 - The product ID on the datasheet is wrong. Fix it in the driver. * IIO_DUMMY_EVGEN - select IRQ_WORK as a dependency. * lpc32xx - make sure clock is prepared before enabling. * si7020 - data byte order was reversed. Fix it. * vf610 - Internal temperature calculation was wrong if a different reference voltage was used. Now use a linear interpolation function to make it work over the full range. - Fix a division by zero in the case of a device tree property not being present (same issue two fixes). * xilinx XADC - VREFN scale was wrong - fix it.

2015-05-10Staging: iio: Allow compile test of GPIO consumers if !GPIOLIBGeert Uytterhoeven
The GPIO subsystem provides dummy GPIO consumer functions if GPIOLIB is not enabled. Hence drivers that depend on GPIOLIB, but use GPIO consumer functionality only, can still be compiled if GPIOLIB is not enabled. Relax the dependency on GPIOLIB if COMPILE_TEST is enabled, where appropriate.
