This change moves all iio_dev debugfs fields to the iio_dev_priv object.
It's not the biggest advantage yet (to the whole thing of abstractization)
but it's a start.
The iio_get_debugfs_dentry() function (which is moved in
industrialio-core.c) needs to also be guarded against the CONFIG_DEBUG_FS
symbol, when it isn't defined. We do want to keep the inline definition in
the iio.h header, so that the compiler can better infer when to compile out
debugfs code that is related to the IIO debugfs directory.

There was a recent discussion about this code:
https://lore.kernel.org/linux-iio/20200322165317.0b1f0674@archlinux/
This looks like a good time to removed this, since any issues about it
should pop-up under testing, because the iio_dev is having a bit of an
overhaul and stuff being moved to iio_dev_opaque.

There are plenty of bad designs we want to discourage or not have to review
manually usually about accessing private (marked as [INTERN]) fields of
'struct iio_dev'.
Sometimes users copy drivers that are not always the best examples.
A better idea is to hide those fields into the framework.
For 'struct iio_dev' this is a 'struct iio_dev_opaque' which wraps a public
'struct iio_dev' object.
In the next series, some fields will be moved to this new struct, each with
it's own rework.
This rework will not be complete-able for a while, as many fields need some
drivers to be reworked in order to finalize them (e.g. 'indio_dev->mlock').
But some fields can already be moved, and in time, all of them may get
there (in the 'struct iio_dev_opaque' object).
Since a lot of drivers also call 'iio_priv()', in order to preserve
fast-paths (where this matters), the public iio_dev object will have a
'priv' field that will have the pointer to the private information already
computed. The reference returned by this field should be guaranteed to be
cacheline aligned.
The opaque parts will be moved into the 'include/linux/iio/iio-opaque.h'
header. Should the hidden information be required for some debugging or
some special needs, it can be made available via this header.
Otherwise, only the IIO core files should include this file.

We may want to get rid of the iio_priv_to_dev() helper. The reason is that
we will hide some of the members of the iio_dev structure (to prevent
drivers from accessing them directly), and that will also mean hiding the
implementation of the iio_priv_to_dev() helper inside the IIO core.
Hiding the implementation of iio_priv_to_dev() implies that some fast-paths
may not be fast anymore, so a general idea is to try to get rid of the
iio_priv_to_dev() altogether.
The iio_priv() helper won't be affected by the rework, as the iio_dev
struct will keep a reference to the private information.
For this driver, not using iio_priv_to_dev(), means reworking some paths to
pass the iio device and using iio_priv() to access the private information,
and also keeping a reference to the iio device for some quirky paths.
One [quirky] path is the at91_adc_workq_handler() which requires the IIO
device & the state struct to push to buffers.
Since this requires the back-ref to the IIO device, the
at91_adc_touch_pos() also uses it. This simplifies the patch a bit. The
information required in this function is mostly for debugging purposes.
Replacing it with a reference to the IIO device would have been a slightly
bigger change, which may not be worth it (for just the debugging purpose
and given that we need the back-ref to the IIO device anyway).

Parts of the saradc probe rely on devm functions and later parts do not.
This makes it more difficult to for example enable triggers via their
devm-functions and would need more undo-work in remove.
So to make life easier for the driver, move the rest of probe calls
also to their devm-equivalents.
This includes moving the clk- and regulator-disabling to a devm_action
so that they gets disabled both during remove and in the error case
in probe, after the action is registered.

All devices using a triggered buffer need to attach and detach the trigger
to the device in order to properly work. Instead of doing this in each and
every driver by hand move this into the core.
At this point in time, all drivers should have been resolved to
attach/detach the poll-function in the same order.
This patch removes all explicit calls of iio_triggered_buffer_postenable()
& iio_triggered_buffer_predisable() in all drivers, since the core handles
now the pollfunc attach/detach.
The more peculiar change is for the 'at91-sama5d2_adc' driver, since it's
not immediately obvious that removing the hooks doesn't break anything.
Eugen was able to test on at91-sama5d2-adc driver, sama5d2-xplained board.

If a driver does not assign an of_node to a IIO device to IIO core will
automatically assign the of_node of the parent device. This automatic
assignment is done in the iio_device_register() function.
There is a fair amount of drivers that currently manually assign the
of_node of the IIO device. All but 4 of them can make use of the automatic
assignment though.
The exceptions are:
* mxs-lradc-adc: Which uses the of_node of the parent of the parent.
* stm32-dfsdm-adc, stm32-adc and stm32-dac: Which reference the of_node
assigned to the IIO device before iio_device_register() is called.
All other drivers are updated to use automatic assignment. This reduces
the amount of boilerplate code involved in setting up the IIO device.
The patch has mostly been auto-generated with the following semantic patch
// <smpl>
@exists@
expression indio_dev;
expression parent;
@@
indio_dev = \(devm_iio_device_alloc\|iio_device_alloc\)(&parent, ...)

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

This assignment is the more peculiar as it assigns the parent of the
platform-device's device (i.e. pdev->dev.parent) as the IIO device's
parent.
Since the devm_iio_device_alloc() [now] assigns the device argument as the
default parent (and since this is the more common case), for cases
where the parent needs to be different, the iio_device_set_parent helper
should be used.
That makes things a bit more obvious about the new behavior of
devm_iio_device_alloc() and makes it clearer that iio_device_set_parent()
should be used.

These were obtained by doing a 'git diff | grep \/\*', in the previous diff
to find comments. These needed a bit more manual review, as the semantic
patch isn't great for catching these.
The result is:
/* Initialize Counter device and driver data */
/* Initialize IIO device */
/* Establish that the iio_dev is a child of the spi device */
/* Estabilish that the iio_dev is a child of the spi device */
/* Initiate the Industrial I/O device */
/* Establish that the iio_dev is a child of the device */
- /* establish that the iio_dev is a child of the i2c device */
- /* establish that the iio_dev is a child of the i2c device */
/* This is only used for removal purposes */
/* setup the industrialio driver allocated elements */
/* variant specific configuration */
/* Setup for userspace synchronous on demand sampling. */
st->readback_delay_us += 5; /* Add tWAIT */
- /* Establish that the iio_dev is a child of the i2c device */
/* Establish that the iio_dev is a child of the i2c device */
Out of which, 4 are really left-over comments about parent assignment.
3 of them are removed by the semantic patch, as the comment removed (by
spatch) would be for an empty line.

This patch applies the semantic patch:
@@
expression I, P, SP;
@@
I = devm_iio_device_alloc(P, SP);
...
- I->dev.parent = P;
It updates 302 files and does 307 deletions.
This semantic patch also removes some comments like
'/* Establish that the iio_dev is a child of the i2c device */'
But this is is only done in case where the block is left empty.
The patch does not seem to cover all cases. It looks like in some cases a
different variable is used in some cases to assign the parent, but it
points to the same reference.
In other cases, the block covered by ... may be just too big to be covered
by the semantic patch.
However, this looks pretty good as well, as it does cover a big bulk of the
drivers that should remove the parent assignment.

By default, the device allocation will also assign a parent device to the
IIO device object. In cases where devm_iio_device_alloc() is used,
sometimes the parent device must be different than the device used to
manage the allocation.
In that case, this helper should be used to change the parent, hence the
requirement to call this between allocation & registration.
This pattern/requirement is not very common in the IIO space, and it may be
cleaned up later.
But until then, assigning the parent manually between allocation &
registration is slightly easier.

The change passes the parent device to the iio_device_alloc() call. This
also updates the devm_iio_device_alloc() call to consider the device object
as the parent device by default.
Having it passed like this, should ensure that any IIO device object
already has a device object as parent, allowing for neater control, like
passing the 'indio_dev' object for other stuff [like buffers/triggers/etc],
and potentially creating iiom_xxx(indio_dev) functions.
With this patch, only the 'drivers/platform/x86/toshiba_acpi.c' needs an
update to pass the parent object as a parameter.
In the next patch all devm_iio_device_alloc() calls will be handled.
