Alexander A. Klimov 3593cd5396 Replace HTTP links with HTTPS ones: drivers/iio
Rationale:
Reduces attack surface on kernel devs opening the links for MITM
as HTTPS traffic is much harder to manipulate.

Deterministic algorithm:
For each file:
  If not .svg:
    For each line:
      If doesn't contain `\bxmlns\b`:
        For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`:
          If both the HTTP and HTTPS versions
          return 200 OK and serve the same content:
            Replace HTTP with HTTPS.

Alexandru Ardelean 8f73a13f74 iio: remove left-over parent assignments
These were found by doing some shell magic:
------------
for file in $(git grep -w devm_iio_device_alloc | cut -d: -f1 | sort | uniq) ; do
	if grep 'parent =' $file | grep -v trig | grep -vq devm_; then
		echo "$file -> $(grep "parent =" $file)"
	fi
done
-----------

The output is bearable [after the semantic patch is applied].
There is a mix of trigger assignments with some iio device parent
assignments that are removed via this patch.

JC: A few more added via inspection of all parent =
statements in drivers/iio. Some of these may just have crossed with this
series, others were less obvious to scripting due to some cross
file / module boundary calls.

Jonathan Cameron a62e256b14 iio:proximity: 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.

Andreas Klinger dc2696ba46 iio: srf08: add support for srf02 in i2c mode
srf02 added with support for i2c interface

Attributes for setting max range or sensitivity are omitted for the case of
srf02 type sensor, because they are not supported by the hardware.

Andreas Klinger c5bf4a0446 iio: srf08: add sensor type srf10
Ultrasonic sensor srf10 is quite similar to srf08 and now also supported by
the driver as device tree compatible string.

It was necessary to prepare the source for supplementary sensors. This is
done by enum srf08_sensor_type.

The most significiant difference between srf08 and srf10 is another range
and values of register gain (in the driver it's call sensitivity).
Therefore the array of it is extended and dependent of the sensor type.

Andreas Klinger c02b3a113d iio: srf08: add device tree table
Added MODULE_DEVICE_TABLE for device tree bindings.

It used to work without it by using the i2c_device_id table, but adding the
table makes everything clear and documented.

Andreas Klinger 78f839029e iio: distance: srf08: add IIO driver for us ranger
This is the IIO driver for devantech srf08 ultrasonic ranger which can be
used to measure the distances to an object.

The sensor supports I2C with some registers.

Supported Features include:
 - read the distance in ranging mode in centimeters
 - output of the driver is directly the read value
 - together with the scale the driver delivers the distance in meters
 - only the first echo of the nearest object is delivered
 - set sensitivity as analog value in the range of 0-31  means setting
   gain register on device
 - set range registers; userspace enters max. range in millimeters in
   43 mm steps

Features not supported by this driver:
 - ranging mode in inches or in microseconds
 - ANN mode
 - change I2C address through this driver
 - light sensor

The driver was added in the directory "proximity" of the iio subsystem and
the menu in den config is now called "Proximity and distance sensors"
