git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-linus Jonathan writes: Second round of IIO fixes for the 4.0 cycle (or round one part two really!) These are fixes for patches in the recent merge window and are in a separate branch to avoid rebasing the main fixes-togreg branch. * jsa1212 - select missing REGMAP_I2C * ssp_common - build warning fix for PM functions when PM not in use. * ak8975 - the addition of a utility library for this driver (as part of adding new device support) led to a dependency not being inforced for the original driver (I2C and GPIOLIB).

git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-linus Jonathan writes: First round of fixes for IIO in the 4.0 cycle. Note a followup set dependent on patches in the recent merge windows will follow shortly. * dht11 - fix a read off the end of an array, add some locking to prevent the read function being interrupted and make sure gpio/irq lines are not enabled for irqs during output. * iadc - timeout should be in jiffies not msecs * mpu6050 - avoid a null id from ACPI emumeration being dereferenced. * mxs-lradc - fix up some interaction issues between the touchscreen driver and iio driver. Mostly about making sure that the adc driver only affects channels that are not being used for the touchscreen. * ad2s1200 - sign extension fix for a result of c type promotion. * adis16400 - sign extension fix for a result of c type promotion. * mcp3422 - scale table was transposed. * ad5686 - use _optional regulator get to avoid a dummy reg being allocate which would cause the driver to fail to initialize. * gp2ap020a00f - select REGMAP_I2C * si7020 - revert an incorrect cleanup up and then fix the issue that made that cleanup seem like a good idea.

2015-02-14IIO: si7020: Allocate correct amount of memory in devm_iio_device_allocAndrey Smirnov
Since only a pointer to struct i2c_client is stored in a private area of IIO device created by the driver there's no need to allocate sizeof(struct i2c_client) worth of storage. Pushed to stable as this is linked to the revert patch previously. Without this followup the original patch looks sensible.

2015-02-14Revert "iio:humidity:si7020: fix pointer to i2c client"Jonathan Cameron
This reverts commit e0922e5e3ccb78aa0152e93dfbd1755ac39c8582. Requested by Andrey Smirnov. It incorrectly assumes that the level of indirection is not needed which is not true(probably because the driver incorrectly allocates sizeof(*client) instead of sizeof(*data) via devm_iio_device_alloc). If you look at the code of the probe function(see below) it is easy to see that what is being stored in the private memory of the IIO device instance is not a copy of a 'struct i2c_client' but a pointer to an instance passed as an argument to the probe function. struct i2c_client **data; int ret; < Some code skipped > indio_dev = devm_iio_device_alloc(&client->dev, sizeof(*client)); if (!indio_dev) return -ENOMEM; data = iio_priv(indio_dev); *data = client; Without reverting this change any read of a raw value of this sensor leads to a kernel oops due to a NULL pointer de-reference on my hardware setup.

2015-02-03Input: ti_am335x_tsc - interchange touchscreen and ADC stepsBrad Griffis
This patch makes the initial changes required to workaround TSC-false pen-up interrupts. It is required to implement these changes in order to remove udelay in the TSC interrupt handler and false pen-up events. The charge step is to be executed immediately after sampling X+. Hence TSC is made to use higher numbered steps (steps 5 to 16 for 5 co-ordinate readouts, 4 wire TSC configuration) and ADC to use lower ones. Further X co-ordinate readouts must be the last to be sampled, thus co-ordinates are sampled in the order Y-Z-X.

2015-01-30iio: add driver for Freescale MMA9553Irina Tirdea
Add support for Freescale MMA9553L Intelligent Pedometer Platform. The following functionalities are supported: - step counter (counts the number of steps using a HW register) - step detector (generates an iio event at every step the user takes) - activity recognition (rest, walking, jogging, running) - speed - calories - distance To get accurate pedometer results, the user's height, weight and gender need to be configured. The specifications can be downloaded from: http://www.freescale.com/files/sensors/doc/ref_manual/MMA955xLSWRM.pdf http://www.freescale.com/files/sensors/doc/ref_manual/MMA9553LSWRM.pdf Signed-off-by: Irina Tirdea <irina.tirdea@intel.com> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
2015-01-29iio: core: Introduce IIO_CHAN_INFO_DEBOUNCE_COUNT and _TIMEIrina Tirdea
The pedometer needs to filter out false steps that might be generated by tapping the foot, sitting, etc. To do that it computes the number of steps that occur in a given time and decides the user is moving only if this value is over a threshold. E.g.: the user starts moving only if he takes 4 steps in 3 seconds. This filter is applied only when the user starts moving. A device that has such pedometer functionality is Freescale's MMA9553L: http://www.freescale.com/files/sensors/doc/ref_manual/MMA9553LSWRM.pdf. To export this feature, this patch introduces IIO_CHAN_INFO_DEBOUNCE_COUNT and IIO_CHAN_INFO_DEBOUNCE_TIME. For the pedometer, in_steps_debounce_count will specify the number of steps that need to occur in in_steps_debounce_time seconds so that the pedometer decides the user is moving.

2015-01-25iio: hid_sensor_hub: Common PM functionsSrinivas Pandruvada
To improvement power and performance, both regular and run time callbacks are introduced. Because of auto suspend delay, two consecutive read don't have to go through full power on/off procedure. The auto suspend time can be adjusted using regular power attributes of PM sysfs.

2015-01-25iio: Add new operating mode for non triggered sw buffersKarol Wrona
There was a need for non triggered software buffer type. It can be used when triggered model does not fit and INDIO_BUFFER_HARDWARE causes confusion because the data stream can be obtained not directly form hardware backend.
