iio: bmg160: IIO_BUFFER and IIO_TRIGGERED_BUFFER are required

2015-08-12T18:24:13Z

This patch adds selects for IIO_BUFFER and IIO_TRIGGERED_BUFFER. Without IIO_BUFFER, the driver does not compile. Signed-off-by: Markus Pargmann Reviewed-by: Srinivas Pandruvada Cc: Signed-off-by: Jonathan Cameron

iio: adis16136: Add ADIS16137 support

2015-08-08T14:09:21Z

The ADIS16137 is register map compatible to the ADIS16136, but has a different scale factor for the gyroscope output. Signed-off-by: Lars-Peter Clausen Signed-off-by: Jonathan Cameron

iio: adis16260: Add ADIS16266 support

2015-08-08T11:58:15Z

The ADIS16266 is mostly register compatible to the ADIS16260. The difference is a different gyroscope scale factor as well not having the relative angular displacement channel. Signed-off-by: Lars-Peter Clausen Signed-off-by: Jonathan Cameron

iio: st-sensors: add configuration for WhoAmI address

2015-07-23T19:43:04Z

This patch permits to configure the WhoAmI register address because some device could have not a standard address for this register. Signed-off-by: Giuseppe Barba Reviewed-by: Denis Ciocca Acked-by: Denis Ciocca Signed-off-by: Jonathan Cameron

iio: Drop owner assignment from i2c_driver

2015-07-11T17:50:07Z

i2c_driver does not need to set an owner because i2c_register_driver() will set it. Signed-off-by: Krzysztof Kozlowski Signed-off-by: Jonathan Cameron

Jonathan writes: Second set of new driver, functionality and cleanups for IIO in the 4.2 cycle. Core functionality * i and q modifiers from quadrature channels. * IIO_CHAN_INFO_OVERSAMPLING_RATIO added. * High pass filter attributes added to mirror the existing low pass filter ones. Core cleanups * Make IIO tools building more cross compiler friendly. * Substantial rework of the function __iio_update_buffers to greatly simplify a hideously evolved function. New drivers and support * ACPI0008 ambient light sensor driver. This one has been around a long time to will be good to finally get it into mainline. * Berlin SOC ADC support. * BMC150 magnetometer. The accelerometer in the same package has been supported for quite some time, so good to have this half as well. * m62332 DAC driver * MEMSIC MMC35420 magnetometer. * ROHM BH1710 and similar ambient light sensors. * Sensortek STK3310 light sensor. * Sensortek STK8312 accelerometer. * Sensortek STK8BA50 accelerometer. * ti-adc128s052 gains support form the adc122s021 2 channel ADC. Driver cleanups and functionality. * Allow various drivers to compile with !GPIOLIB if COMPILE_TEST enabled. * bmc150 - decouple trigger from buffer to allow other triggers to be used. * bmg160 - decouple trigger from buffer to allow other triggers to be used. Fix a trivial unused field. * Constify a load of platform_device_id structures. * inv_mpu6050 - device tree bindings. * hid-sensors - fix a memory leak during probe if certain errors occur. * ltr501 - illuminance channel derived (in an non obvious fashion) from the intensity channels. * ltr501 - fix a boundary check on the proximity threshold. * mlx90614 - drop a pointless return. * mma8452 - Debugfs register access and fix a bug that had no effect (by coincidence) * ti_am335x_adc - add device tree bindings for sample-delay, open-delay and averaging. The ideal settings for these tend to be board design specific.

iio: gyro: bmg160: decouple buffer and triggers

2015-05-17T09:26:54Z

Make it possible to use buffering with an external trigger, such as one based on sysfs or hrtimer. Signed-off-by: Vlad Dogaru Signed-off-by: Jonathan Cameron

iio: gyro: bmg160: remove redundant field

2015-05-17T09:24:36Z

Replace the 'timestamp' field in struct bmg160_data with the identically named field in iio_poll_func and with calls to iio_get_time_ns(). The reported timestamps may be slightly different, but the advantage is that we no longer assume that the buffer of bmg160 is triggered by its own trigger.

iio: gyro: hid-sensor-gyro-3d: Fix memory leak in probe()

2015-05-17T08:09:49Z

'channels' is allocated via kmemdup and it is never freed in the subsequent error paths. Use 'indio_dev->channels' directly instead, so that we avoid such memory leak problem. Signed-off-by: Fabio Estevam Reviewed-by: Srinivas Pandruvada Signed-off-by: Jonathan Cameron

Jonathan writes: The usual mixed bag of fixes for IIO in the 4.1 cycle. 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.
