iio:magnetometer: bugfix magnetometers gain values

2014-09-14T17:21:23+00:00

This patch fix gains values. The first driver was designed using engineering samples, in mass production the values are changed. Signed-off-by: Denis Ciocca Cc: Stable@vger.kernel.org Signed-off-by: Jonathan Cameron

Jonathan writes: Fourth round of IIO new drivers, functionality and cleanups for the 3.17 cycle New functionality * A new modifier to indicate that a rotation is relative to either true or magnetic north. This is to be used by some magnetometers that provide data in this way. * hid magnetometer now supports output rotations from various variants on North * HMC5843 driver converted to regmap and reworked to allow easy support of other similar devices. Support for HMC5983 added via both i2c and SPI. * Rework of Exynos driver to simplify extension to support more devices. * Addition of support for the Exynos3250 ADC (which requires an additional clock) Support for quite a few more devices on its way. Cleanups * ad7997 - a number of cleanups and tweaks to how the events are controlled to make it more intuitive. * kxcjk - cleanups and minor fixes for this new driver.

iio: hid-sensor-magn-3d: Add support for rotation from north

2014-07-20T12:39:35+00:00

Add the HID usage attribute ID's and IIO channel info for rotation from north support. Signed-off-by: Reyad Attiyat Acked-by: Srinivas Pandruvada Signed-off-by: Jonathan Cameron

iio: hid-sensor-magn-3d: Scan for usage attributes before setting up iio channels

2014-07-20T12:37:52+00:00

Scan for and count the HID usage attributes supported by the driver. This allows for the driver to only setup the IIO channels for the sensor usages present in the HID USB reports.

iio: st_sensors: add devicetree probing support

2014-07-11T20:09:49+00:00

The I2C devices that make up the STMicroelectronics MEMS sensors may be sneakily enabled by cleverly giving the device node the same name as a string match from the platform device ID table. However the right method is to use the compatible string. On detection, the ST sensors use the ID string to probe and instatiate the right sensor driver, so pass the kernel-internal ID string in the .data field of the OF match table, and set the I2C client name to this name when a compatible match is used. This avoids having misc Linux-specific strings floating around in the device tree. Cc: Lee Jones Cc: Denis CIOCCA Signed-off-by: Linus Walleij Signed-off-by: Jonathan Cameron

iio: hid-sensor-magn-3d: Fix return values

2014-07-05T10:07:12+00:00

IIO_CHAN_INFO_SAMP_FREQ and IIO_CHAN_INFO_HYSTERESIS cases ignored the actual return values (which could be -EINVAL) and instead returned IIO_VAL_INT_PLUS_MICRO always. Return the actual value obtained from the functions. Both functions return IIO_VAL_INT_PLUS_MICRO upon success. Signed-off-by: Sachin Kamat Cc: Srinivas Pandruvada Signed-off-by: Jonathan Cameron

Jonathan writes: Second round of new drivers and cleanups for IIO in the 3.17 cycle. New drivers * mcp4902, mcp4912 and mcp4922 SPI DAC driver. * max1027, max1029 and max1031 SPI ADC driver. Cleanups * cm32181 - use devm APIs to simplify error paths. * ak8975 - use devm APIs to simplify error paths. * ad9850 - drop some unused defines and an unnecessary goto. * hmc5843 - add missing devices to the device id table and the documentation. * ad9832 - small formatting cleanups. * sca3000 - hide direct use of the stufftoread element by adding a data_available function. This is a precursor for the addition of buffer watermarks to the subsystem but stands as a good cleanup on its own.
