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

iio: remove .owner field for driver using module_platform_driver

2014-08-26T20:08:38+00:00

This patch removes the .owner field for drivers which use the platform_driver_register api because this is overriden in _platform_driver_register. Signed-off-by: Sanjeev Sharma Signed-off-by: Jonathan Cameron

iio: hid-sensor-magn-3d: Fix build warning

2014-07-27T13:16:29+00:00

Fix build warning, sizeof() called on dynamically sized pointer, by removing the call and the dependent function parameter. It is not needed or used in this driver, when pushing values to an iio buffer. Changes from v1 - Fix mistake in varible name Signed-off-by: Reyad Attiyat 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.
