iio: adis16480: Fix scale factors

2015-09-21T17:02:16+00:00

commit 7abad1063deb0f77d275c61f58863ec319c58c5c upstream.

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

iio: industrialio-buffer: Fix iio_buffer_poll return value

2015-09-21T17:02:15+00:00

commit 1bdc0293901cbea23c6dc29432e81919d4719844 upstream.

Change return value to 0 if no device is bound since
unsigned int cannot support negative error codes.

device has been unregistered")

iio: event: Remove negative error code from iio_event_poll

2015-09-21T17:02:15+00:00

commit 41d903c00051d8f31c98a8136edbac67e6f8688f upstream.

Negative return values are not supported by iio_event_poll since
its return type is unsigned int.

iio: bmg160: IIO_BUFFER and IIO_TRIGGERED_BUFFER are required

2015-09-21T17:02:15+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: adc: at91_adc: allow to use full range of startup time

2015-08-03T16:29:53+00:00

commit 2ab5f39bc7825808e0fa1e7e5f0b23e174563467 upstream.

The DT-Property "atmel,adc-startup-time" is stored in an u8 for a microsecond
value. When trying to increase the value of STARTUP in Register AT91_ADC_MR
some higher values can't be reached.

Change the type in function parameter and private structure field from u8 to
u32.

commit 8d05abfaeff52bdf66aba3a3a337dcdbdb4911bf upstream.

only SAMP_FREQ is writable

Will lead to SAMP_FREQ being written by any attempt to write
to the other exported attributes and hence a rather unexpected
result!

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

2015-08-03T16:29:53+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

2015-06-23T00:01:19+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

2015-06-23T00:01:19+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.
