iio: adis16480: Fix scale factors

2015-09-21T17:00:07+00:00

commit 7abad1063deb0f77d275c61f58863ec319c58c5c upstream.

The different devices support by the adis16480 driver have slightly
different scales for the gyroscope and accelerometer channels.

iio: bmg160: IIO_BUFFER and IIO_TRIGGERED_BUFFER are required

2015-09-21T17:00:07+00:00

commit 06d2f6ca5a38abe92f1f3a132b331eee773868c3 upstream.

This patch adds selects for IIO_BUFFER and IIO_TRIGGERED_BUFFER. Without
IIO_BUFFER, the driver does not compile.

iio: DAC: ad5624r_spi: fix bit shift of output data value

2015-08-03T16:29:43+00:00

commit adfa969850ae93beca57f7527f0e4dc10cbe1309 upstream.

The value sent on the SPI bus is shifted by an erroneous number of bits.
The shift value was already computed in the iio_chan_spec structure and
hence subtracting this argument to 16 yields an erroneous data position
in the SPI stream.

iio: adis16400: Compute the scan mask from channel indices

2015-06-22T23:55:52+00:00

commit c2a8b623a089d52c199e305e7905829907db8ec8 upstream.

We unfortunately can't use ~0UL for the scan mask to indicate that the
only valid scan mask is all channels selected. The IIO core needs the exact
mask to work correctly and not a super-set of it. So calculate the masked
based on the channels that are available for a particular device.

iio: adis16400: Use != channel indices for the two voltage channels

2015-06-22T23:55:51+00:00

commit 7323d59862802ca109451eeda9777024a7625509 upstream.

Previously, the two voltage channels had the same ID, which didn't cause
conflicts in sysfs only because one channel is named and the other isn't;
this is still violating the spec though, two indexed channels should never
have the same index.

iio: imu: Use iio_trigger_get for indio_dev->trig assignment

2015-04-19T08:10:49+00:00

commit 4ce7ca89d6e8eae9e201cd0e972ba323f33e2fb4 upstream.

This patch uses iio_trigger_get to increment the reference
count of trigger device, to avoid incorrect assignment.
Can result in a null pointer dereference during removal if the
trigger has been changed before removal.

This patch refers to a similar situation encountered through the
following discussion:

iio: inv_mpu6050: Clear timestamps fifo while resetting hardware fifo

commit 4dac0a8eefd55bb1f157d1a5a084531334a2d74c upstream.

A hardware fifo reset always imply an invalidation of the
existing timestamps, so we'll clear timestamps fifo on
successfull hardware fifo reset.

iio: imu: adis16400: Fix sign extension

2015-03-18T12:22:29+00:00

commit 19e353f2b344ad86cea6ebbc0002e5f903480a90 upstream.

The intention is obviously to sign-extend a 12 bit quantity. But
because of C's promotion rules, the assignment is equivalent to "val16
&= 0xfff;". Use the proper API for this.
