2015-10-12iio:measurement specialties core: Fix endian sparse warnings.Jonathan Cameron
This patch changes various types to the appropriate endian specific versions. Also introduces an additional local variable to avoid a single variable being used for both be and cpu endianness. These aren't bugs as such, but clearing them up does make the code clearer.

Commit 845c877009cf014b ("i2c / ACPI: Assign IRQ for devices that have GpioInt automatically") automatically assigns the first ACPI GPIO interrupt in client->irq, so we can remove the probing code from drivers that use only one interrupt.

Since commit dab472eb931bc291 ("i2c / ACPI: Use 0 to indicate that device does not have interrupt assigned") 0 is not a valid i2c client irq anymore, so change all driver's checks accordingly.

2015-10-03iio: mlx96014: Error checking from positive to negativeCrt Mori
Dan Carpenter reported a static checker report and after his mail I noticed that we actually return from function if positive value is obtained from i2c read. This was remainder from when code was not in separate function (which I changed during the review process). Static checker reported drivers/iio/temperature/mlx90614.c:167 mlx90614_iir_search() warn: this cast is a no-op which meant that cast before negating is useless. Dan also proposed a solution on nicer bit operation form. Also changed magic number to macro in process as that was confusing.

Tools * event-monitor - report unsupported events. We keep expanding what can come from drivers so give a helpful error if one turns up in an out of date userspace program. * generic-buffer - helpful message about needing to enable a channel to start the buffer.

This platform driver has a OF device ID table but the OF module alias information is not created so module autoloading won't work. Signed-off-by: Luis de Bethencourt <luisbg@osg.samsung.com> Signed-off-by: Jonathan Cameron <jic23@kernel.org>

2015-09-23iio: mma8452: leave sysfs namings to the iio coreMartin Kepplinger
This doesn't actually change anything since the core names the sysfs folder for the iio event attributes "events" anyways. It only leaves the job to the core.

2015-09-23iio: mma8452: add support for MMA8652FC and MMA8653FCMartin Kepplinger
MMA8652FC and MMA8653FC don't provide the transient interrupt source, so the motion interrupt source is used by providing a new iio_chan_spec definition, so that other supported devices are not affected by this. Datasheets for the newly supported devices are available at Freescale's website: http://cache.freescale.com/files/sensors/doc/data_sheet/MMA8652FC.pdf http://cache.freescale.com/files/sensors/doc/data_sheet/MMA8653FC.pdf Signed-off-by: Martin Kepplinger <martin.kepplinger@theobroma-systems.com> Signed-off-by: Christoph Muellner <christoph.muellner@theobroma-systems.com> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
2015-09-23iio: mma8452: add freefall / motion interrupt sourceMartin Kepplinger
This adds the freefall / motion interrupt source definitions to the driver. It is used in this series' next patch, for chips that don't support the transient interrupt source.

2015-09-23iio: mma8452: add support for MMA8453Q accelerometer chipMartin Kepplinger
This adds support for the 10 bit version if Freescale's accelerometers of this series. The datasheet is available at Freescale's website: http://cache.freescale.com/files/sensors/doc/data_sheet/MMA8453Q.pdf It creates a devicetree bindings file to document the new functionality and removes the driver from the trivial-devices list.

2015-09-23iio: mma8452: refactor for seperating chip specific dataMartin Kepplinger
This adds a struct mma_chip_info to hold data that will remain specific to the chip in use. It is provided during probe() and linked in struct of_device_id. Also this suggests that the driver is called "mma8452" and now handles the MMA8452Q device, but is not limited to it.
