2018-03-07iio: Replace occurrences of magic number 0 by IIO_CHAN_INFO_RAWRodrigo Siqueira1-1/+1
Usually, functions responsible for reading raw data typically relies on values from iio_chan_info_enum to correctly identify the type of data to be read. There is a set of a device driver that uses the magic number 0 instead of IIO_CHAN_INFO_RAW. This patch improves the readability by replaces the magic number 0 for the appropriate IIO_CHAN_INFO_RAW in six devices driver in the IIO subsystem.

2017-08-22iio:light: drop assign iio_info.driver_module and iio_trigger_ops.ownerJonathan Cameron1-1/+0
The equivalent of both of these are now done via macro magic when the relevant register calls are made. The actual structure elements will shortly go away. Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com> Reviewed-by: Lars-Peter Clausen <lars@metafoo.de>
2017-04-02iio: light: lm3533-als: constify attribute_group structuressimran singhal1-2/+2
Check for attribute_group structures that are only stored in the event_attrs filed of iio_info structure. As the event_attrs field of iio_info structures is constant, so these attribute_group structures can also be declared constant. Done using coccinelle: @r1 disable optional_qualifier @ identifier i; position p; @@ static struct attribute_group i@p = {...}; @ok1@ identifier r1.i; position p; struct iio_info x; @@ x.event_attrs=&i@p; @bad@ position p!={r1.p,ok1.p}; identifier r1.i; @@ i@p @depends on !bad disable optional_qualifier@ identifier r1.i; @@ static +const struct attribute_group i={...}; @depends on !bad disable optional_qualifier@ identifier r1.i; @@ +const struct attribute_group i; As the attrs field of iio_info structures is also constant, so these attribute_group structures can also be declared constant.

2016-06-30iio:core: timestamping clock selection supportGregor Boirie1-1/+1
Adds a new per-device sysfs attribute "current_timestamp_clock" to allow userspace to select a particular POSIX clock for buffered samples and events timestamping. Following clocks, as listed in clock_gettime(2), are supported: CLOCK_REALTIME, CLOCK_MONOTONIC, CLOCK_MONOTONIC_RAW, CLOCK_REALTIME_COARSE, CLOCK_MONOTONIC_COARSE, CLOCK_BOOTTIME and CLOCK_TAI.

2013-01-03Drivers: iio: remove __dev* attributes.Greg Kroah-Hartman1-10/+9
CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, and __devexit from these drivers. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand.

2012-06-04iio: add LM3533 ambient-light-sensor driverJohan Hovold1-0/+932
Add sub-driver for the ambient-light-sensor interface on National Semiconductor / TI LM3533 lighting power chips. The sensor interface can be used to control the LEDs and backlights of the chip through defining five light zones and three sets of corresponding output-current values. The driver provides raw and mean adc readings along with the current light zone through sysfs. A threshold event can be generated on zone changes. The ALS-control output values can be set per zone for the three current output channels.
