Use `\t(\{ ?\},|\{\}|\{\s*/\*.*\*/\s*\},?)$` regex to find and replace
the array sentinel in all IIO drivers to the same style.
For some time, we've been trying to consistently use `{ }` (no trailing
comma, no comment, one space between braces) for array sentinels in the
IIO subsystem. Still nearly 50% of existing code uses a different style.
To save reviewers from having to request this trivial change as
frequently, let's normalize the style in all existing IIO drivers.
At least when code is copy/pasted to new drivers, the style will be
consistent.

write_event_config callback use an int for state, but it is actually a
boolean. iio_ev_state_store is actually using kstrtobool to check user
input, then gives the converted boolean value to write_event_config.
Fix signature and update all iio drivers to use the new signature.
This patch has been partially written using coccinelle with the
following script:
$ cat iio-bool.cocci
// Options: --all-includes
virtual patch
@c1@
identifier iioinfo;
identifier wecfunc;
@@
static const struct iio_info iioinfo = {
...,
.write_event_config =
(
wecfunc
|
&wecfunc
),
...,
};
@@
identifier c1.wecfunc;
identifier indio_dev, chan, type, dir, state;
@@
int wecfunc(struct iio_dev *indio_dev, const struct iio_chan_spec *chan, enum iio_event_type type, enum iio_event_direction dir,
-int
+bool
state) {
...
}
make coccicheck MODE=patch COCCI=iio-bool.cocci M=drivers/iio
Unfortunately, this script didn't match all files:
* all write_event_config callbacks using iio_device_claim_direct_scoped
were not detected and not patched.
* all files that do not assign and declare the write_event_config
callback in the same file.
iio.h was also manually updated.
The patch was build tested using allmodconfig config.

After commit b8a1a4cd5a98 ("i2c: Provide a temporary .probe_new()
call-back type"), all drivers being converted to .probe_new() and then
03c835f498b5 ("i2c: Switch .probe() to not take an id parameter") convert
back to (the new) .probe() to be able to eventually drop .probe_new() from
struct i2c_driver.

I2C does not by default use buffers directly for DMA so there is
no need to ensure they are DMA safe.

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.

Proximity sensor driver based on light/vcnl4000.c code.
For now supports only the single on-demand measurement.
The VCNL3020 is a fully integrated proximity sensor. Fully
integrated means that the infrared emitter is included in the
package. It has 16-bit resolution. It includes a signal
processing IC and features standard I2C communication
interface. It features an interrupt function.
