Rodrigo Siqueira 67464a54e5 iio: Replace occurrences of magic number 0 by IIO_CHAN_INFO_RAW
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.

Jonathan Cameron 4166b47c2b iio:light: drop assign iio_info.driver_module and iio_trigger_ops.owner
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.

simran singhal 98b6d2b676 iio: light: lm3533-als: constify attribute_group structures
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. Done manually.

Gregor Boirie bc2b7dab62 iio:core: timestamping clock selection support
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.

Greg Kroah-Hartman fc52692c49 Drivers: iio: remove __dev* attributes.
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.

Johan Hovold 9c8ea1b29b iio: add LM3533 ambient-light-sensor driver
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.
