2017-01-10iio:kfifo_buf header include push down.Jonathan Cameron
As a precursor to splitting buffer.h, lets make sure all drivers include the relevant headers rather than relying on picking them up from kfifo_buf.h. Signed-off-by: Jonathan Cameron <jic23@kernel.org> Reviewed-by: Lars-Peter Clausen <lars@metafoo.de>
2015-10-28spi: Drop owner assignment from spi_driversAndrew F. Davis
An spi_driver does not need to set an owner, it will be populated by the driver core. Signed-off-by: Andrew F. Davis <afd@ti.com> Acked-by: Jonathan Cameron <jic23@kernel.org> Signed-off-by: Mark Brown <broonie@kernel.org>
2015-07-05iio: ssp_sensors: Remove redundant spi driver bus initializationAntonio Borneo
In ancient times it was necessary to manually initialize the bus field of an spi_driver to spi_bus_type. These days this is done in spi_register_driver(), so we can drop the manual assignment.

2015-01-31iio:common:ssp_sensors fix warnings due to 32 bit instead of 64 bit passed ↵Jonathan Cameron
to do_div Also change to div64_u64 in one place to avoid loss of precision (was dividing a 32 bit number by a 64 bit number, but casting this to 64 bit divided by 32 bit) Those divide functions certainly have esoteric naming! Fixes warnings with asm-generic/div64.h do_div such as: In file included from drivers/iio/common/ssp_sensors/ssp_iio.c:20:0: drivers/iio/common/ssp_sensors/ssp_iio_sensor.h: In function 'ssp_convert_to_freq': >> drivers/iio/common/ssp_sensors/ssp_iio_sensor.h:56:16: warning: comparison of distinct pointer types lacks a cast [enabled by default] drivers/iio/common/ssp_sensors/ssp_iio_sensor.h:56:2: warning: right shift count >= width of type [enabled by default] >> drivers/iio/common/ssp_sensors/ssp_iio_sensor.h:56:2: warning: passing argument 1 of '__div64_32' from incompatible pointer type [enabled by default] include/asm-generic/div64.h:35:17: note: expected 'uint64_t *' but argument is of type 'int *' drivers/iio/common/ssp_sensors/ssp_iio.c: In function 'ssp_common_process_data': include/linux/iio/buffer.h:142:32: warning: 'calculated_time' may be used uninitialized in this function [-Wuninitialized] drivers/iio/common/ssp_sensors/ssp_iio.c:83:10: note: 'calculated_time' was declared here Fixed by using straight coded version as per the description in the div64.h header, thus ensuring no issue with 32 bit integers.

2015-01-29iio: common: ssp_sensors: Add sensorhub driverKarol Wrona
Sensorhub is MCU dedicated to collect data and manage several sensors. Sensorhub is a spi device which provides a layer for IIO devices. It provides some data parsing and common mechanism for sensorhub sensors. Adds common sensorhub library for sensorhub driver and iio drivers which uses sensorhub MCU to communicate with sensors.
