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.

2015-11-08iio: Reconcile operation order between iio_register/unregister and pm functionsAdriana Reus1-10/+9
At probe, runtime pm should be setup before registering the sysfs interface so that all the power attributes are accurate and functional when registering. Also, when removing the device we should unregister first to make sure that the interfaces that may result in wakeups are no longer available. Fix this behaviour for the following drivers: bmc150, bmg160, kmx61, kxcj-1013, mma9551, mma9553, rpr0521.

Second version of this pull request as a small fix to a fix turned up before Greg pulled it for a cc10001 patch near the top of the tree. One core fix * Set updated for a iio kfifo was incorrectly set to false during a failed update, resulting in atttempts to repeat the failed operation appearing to succeed. This time I've decided to list the driver fixes in alphabetical order rather than 'randomly'. * axp288_adc - a recent change added a check for valid info masks when reading channels from consumer drivers. * bmp280 - temperature compensation was failing to read the tfine value, hence causing a temperature of 0 to always be returned and incorrect presure measurements. * cc10001 - Fix channel number mapping when some channels are reserved for remote CPUs. Fix an issue with the use of the power-up/power-down register (basically wrong polarity). Fix an issue due to the missinterpretting the return value from regulator_get_voltage. Add a delay before the start bit as recommended for the hardware to avoid data corruption. * hid pressure - fix channel spec of modfiied, but no modifier (which makes no sense!) * hid proximity - fix channel spec of modified, but no modifier (which makes no sense!). Fix a memory leak in the probe function. * mcp320x - occasional incorrect readings on dma using spi busses due to cacheline corruption. Fixed by forcing ___cacheline_aligned for the buffers. * mma9551 - buffer overrun fix (miss specified maximum length of buffers) * mma9553 - endian fix on status message. Add an enable element for activity channel. Input checking for activity period to avoid rather unpredictable results. * spmi-vadc - fix an overflow in the output value normalization seen on some boards. * st-snesors - oops due to use of a mutex that is not yet initialized during probe. * xilinx adc - Some wrong register addresses, a wrong address for vccaux channel, incorrect scale on VREFP and incorrect sign on VREFN.

git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging Pull staging driver updates from Greg KH: "Here's the big staging tree pull request for 3.19-rc1. We continued to delete more lines than were added, always a good thing, but not at a huge rate this release, only about 70k lines removed overall mostly from removing the horrid bcm driver. Lots of normal staging driver cleanups and fixes all over the place, well over a thousand of them, the shortlog shows all the horrid details. The "contentious" thing here is the movement of the Android binder code out of staging into the "real" part of the kernel. This is code that has been stable for a few years now and is working as-is in the tens of millions of devices with no issues. Yes, the code is horrid, and the userspace api leaves a lot to be desired, but it's not going to change due to legacy issues that we have no control over. Because so many devices and companies rely on this, and the code is stable, might as well promote it out of staging. This was all discussed at the Linux Plumbers conference, and everyone participating agreed that this was the best way forward. There is work happening to replace the binder code with something new that is happening right now, but I don't expect to see the results of that work for another year at the earliest. If that ever happens, and Android switches over to it, I'll gladly remove this version. As for maintainers, I'll be glad to maintain this code, I've been doing it for the past few years with no problems. I'll send a MAINTAINERS entry for it before 3.19-final is out, still need to talk to the Google developers about if they are willing to help with it or not, last I checked they were, which was good.

2014-11-16iio: gyro: bmg160: Don't let interrupt mode to be open drainSrinivas Pandruvada1-0/+16
Change the mode to push/pull type instead of open drain as some platforms fails to drive the GPIO pin with open drain. Signed-off-by: Srinivas Pandruvada <srinivas.pandruvada@linux.intel.com> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
2014-11-16iio: gyro: bmg160: Error handling when mode set failsSrinivas Pandruvada1-1/+13
When mode set fails due to some transient failures, it will atleast reset the state of runtime usage count and also let the runtime suspend retry from the driver framework. Signed-off-by: Srinivas Pandruvada <srinivas.pandruvada@linux.intel.com> Signed-off-by: Jonathan Cameron <jic23@kernel.org>

git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next Jonathan writes: First round of new drivers, features and cleanups for IIO in the 3.19 cycle. New drivers / supported parts * rockchip - rk3066-tsadc variant * si7020 humidity and temperature sensor * mcp320x - add mcp3001, mcp3002, mcp3004, mcp3008, mcp3201, mcp3202 * bmp280 pressure and temperature sensor * Qualcomm SPMI PMIC current ADC driver * Exynos_adc - support exynos7 New features * vf610-adc - add temperature sensor support * Documentation of current attributes, scaled pressure, offset and scaled humidity, RGBC intensity gain factor and scale applied to differential voltage channels. * Bring iio_event_monitor up to date with newer modifiers. * Add of_xlate function to allow for complex channel mappings from the device tree. * Add -g parameter to generic_buffer example to allow for devices with directly fed (no trigger) buffers. * Move exynos driver over to syscon for PMU register access. Cleanups, fixes for new drivers * lis3l02dq drop an unneeded else. * st sensors - renam st_sensors to st_sensor_settings (for clarity) * st sensors - drop an unused parameter from all the probe utility functions. * vf610 better error handling and tidy up. * si7020 - cleanups following merge * as3935 - drop some unnecessary semicolons. * bmp280 - fix the pressure calculation.

2014-09-14iio: gyro: bmi055 gyro sensor driverIrina Tirdea2-13/+28
Add support for the BMI055 gyroscope sensor. BMI055 is a package consisting of an acceleration sensor and a gyroscope. This patch adds support for the gyroscope only. Spec downloaded from: http://ae-bst.resource.bosch.com/media/products/dokumente/bmi055/BST-BMI055-DS000-06.pdf The BMI055 gyroscope uses the same register definition as BMG160, but does not specify a temp register. However, the temp register seems to be working in the same way as for BMG160, so this patch does not remove the temp channel for BMI055.

2014-09-14iio: gyro: bmg160: only set power state if PM_RUNTIME is definedIrina Tirdea1-0/+2
When CONFIG_PM_RUNTIME is not defined and bmg160 tries to power off the device, bmg160_set_power_state will call pm_runtime_put_autosuspend, which is not implemented (wil return -ENOSYS). Only call bmg160_set_power_state when CONFIG_PM_RUNTIME is defined.
