iio: accel: kxsd9: Fix scaling bug

2016-10-06T02:40:20+00:00

[ Upstream commit 307fe9dd11ae44d4f8881ee449a7cbac36e1f5de ] All the scaling of the KXSD9 involves multiplication with a fraction number < 1. However the scaling value returned from IIO_INFO_SCALE was unpredictable as only the micros of the value was assigned, and not the integer part, resulting in scaling like this: $cat in_accel_scale -1057462640.011978 Fix this by assigning zero to the integer part.

iio: accel: kxsd9: Fix raw read return

2016-09-12T22:59:48+00:00

[ Upstream commit 7ac61a062f3147dc23e3f12b9dfe7c4dd35f9cb8 ] Any readings from the raw interface of the KXSD9 driver will return an empty string, because it does not return IIO_VAL_INT but rather some random value from the accelerometer to the caller.

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

2015-08-27T17:26:03+00:00

[ Upstream commit b136faff9bc2f4adea050ed2119c01199f9a86a5 ] '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.

iio: bmc150: change sampling frequency

2015-04-24T21:13:51+00:00

[ Upstream commit 0ba8da961bd868c67a8dae3dbbee145514515e9c ] Currently driver reports device bandwidth list as available sampling frequency. But sampling frequency is actually twice the device bandwidth. This patch fixes this issue.

iio: accel: bmc150: set low default thresholds

2014-11-16T20:25:00+00:00

Set the threshold to low by default. With this thresholds any movement on the device with this sensor will generate event. Signed-off-by: Srinivas Pandruvada Signed-off-by: Jonathan Cameron

iio: accel: bmc150: Fix iio_event_spec direction

2014-11-16T20:23:48+00:00

Change event spec direction from IIO_EV_DIR_RISING | IIO_EV_DIR_FALLING to IIO_EV_DIR_EITHER Suggested-by: Daniel Baluta Signed-off-by: Srinivas Pandruvada Signed-off-by: Jonathan Cameron

iio: accel: bmc150: Send x, y and z motion separately

2014-11-16T20:22:39+00:00

This chip is capable to identify motion across x, y and z axes. So send different events. Signed-off-by: Srinivas Pandruvada Signed-off-by: Jonathan Cameron

iio: accel: bmc150: Error handling when mode set fails

2014-11-16T20:22:34+00:00

When mode set fails due to some transient failures, it will atleast reset the state of runtime usage count and also let the runtime suspend retry from the driver framework. Signed-off-by: Srinivas Pandruvada Signed-off-by: Jonathan Cameron

iio: accel: kxcjk-1013: Fix kxcjk10013_set_range

2014-11-15T16:11:28+00:00

Currently, we get the new GSEL bits by OR-ing the old values with the new ones. This only works first time when the old values are 0. Startup: * GSEL0 = 0, GSEL1 = 0 Set range to 4G: (GSEL0 = 1, GSEL1 = 0) * GSEL0 = 0 | 1 = 1 * GSEL1 = 0 | 0 = 0 * correct Change range to 2G: (GSEL0 = 0, GSEL1 = 0) * GSEL0 = 1 | 0 = 1 * GSEL1 = 0 | 0 = 0 * wrong, GSEL0 should be 0 This has the nice effect that we can use the full scale range, exported in in_accel_scale_available.

io: accel: kxcjk-1013: Fix iio_event_spec direction

2014-11-05T18:33:46+00:00

Because IIO_EV_DIR_* are not bitmasks but enums, IIO_EV_DIR_RISING | IIO_EV_DIR_FALLING is not equal with IIO_EV_DIR_EITHER. This could lead to potential misformatted sysfs attributes like: * in_accel_x_thresh_(null)_en * in_accel_x_thresh_(null)_period * in_accel_x_thresh_(null)_value or even memory corruption.
