Jonathan Cameron 53469fa5c5 iio:adc:max1027: drop of_match_ptr and CONFIG_OF protections
These just prevent the driver being used with ACPI PRP0001
and provide no major benefits.

Part of clearing these out in general in IIO to avoid cut and paste
repetition in new drivers.  Also include mod_devicetable.h as we
directly make use of of_device_id which is defined in there.

Lars-Peter Clausen 8cb631ccbb iio: Remove superfluous of_node assignments
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, ...)
...
-indio_dev->dev.of_node = parent.of_node;

Alexandru Ardelean d3be83244c iio: remove explicit IIO device parent assignment
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.

Miquel Raynal 7af5257d84 iio: adc: max1027: Prepare the introduction of different resolutions
Maxim's max1027/29/31 series returns the measured voltages with a
resolution of 10 bits. There is a very similar series, max1227/29/31
which works identically but uses a resolution of 12 bits. Prepare the
support for these chips by turning the 'depth' into a macro parameter
instead of hardcoding it everywhere. Also reorganize just a bit the
macros at the top to avoid repeating tens of lines when adding support
for a new chip.

Miquel Raynal ffae106764 iio: adc: max1027: Make it optional to use interrupts
The chip has a 'start conversion' and a 'end of conversion' pair of
pins. They can be used but this is absolutely not mandatory as regular
polling of the value is totally fine with the current internal
clocking setup. Turn the interrupts optional and do not error out if
they are not inquired in the device tree. This has the effect to
prevent triggered buffers use though.

Miquel Raynal 038696f8bd iio: adc: max1027: Add debugfs register read support
Until now, only write operations were supported. Force two bytes read
operation when reading, which should fit most of the development
purposes. Of course, extended operations like buffered reads on
multiple channels or even temperature + voltage reads will not be read
entirely. Usually, just starting a new operation will work but in any
case a software reset (done through the debufs interface too) will
return the device in a usable state.

Kees Cook 3c4211ba8a treewide: devm_kmalloc() -> devm_kmalloc_array()
The devm_kmalloc() function has a 2-factor argument form,
devm_kmalloc_array(). This patch replaces cases of:

        devm_kmalloc(handle, a * b, gfp)

with:
        devm_kmalloc_array(handle, a * b, gfp)

as well as handling cases of:

        devm_kmalloc(handle, a * b * c, gfp)

with:

        devm_kmalloc(handle, array3_size(a, b, c), gfp)

as it's slightly less ugly than:

        devm_kmalloc_array(handle, array_size(a, b), c, gfp)

This does, however, attempt to ignore constant size factors like:

        devm_kmalloc(handle, 4 * 1024, gfp)

though any constants defined via macros get caught up in the conversion.

Any factors with a sizeof() of "unsigned char", "char", and "u8" were
dropped, since they're redundant.

Some manual whitespace fixes were needed in this patch, as Coccinelle
really liked to write "=devm_kmalloc..." instead of "= devm_kmalloc...".

The Coccinelle script used for this was:

Javier Martinez Canillas d1b895feda iio: adc: max1027: Set struct spi_driver .of_match_table
The driver has an OF id table but the .of_match_table is not set so
the SPI core can't do an OF style match and the table was unused.
