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;
@exists@

...
-indio_dev->dev.of_node = parent->of_node;

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.

!!'s behaviour isn't that obvious and sparse complained about it, so
let's replace it with a ternary condition.

The X-Powers AXP813 PMIC is really close to what is already done for
AXP20X/AXP22X.
There are two pairs of bits to set the rate (one for Voltage and Current
measurements and one for TS/GPIO0 voltage measurements) instead of one.
The register to set the ADC rates is different from the one for
AXP20X/AXP22X.
GPIO0 can be used as an ADC (measuring Volts) unlike for AXP22X.
The scales to apply to the different inputs are unlike the ones from
AXP20X and AXP22X.

To prepare for a future patch that will add a DT node for the ADC, make
axp20x_adc able to probe from DT and get the per-variant data from
of_device_id.data since platform_device_id.driver_data won't be set when
probing by DT.
Leave the ability to probe via platform for driver compatibility with
old DTs.

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.

The X-Powers AXP20X and AXP22X PMICs have multiple ADCs. They expose the
battery voltage, battery charge and discharge currents, AC-in and VBUS
voltages and currents, 2 GPIOs muxable in ADC mode and PMIC temperature.
This adds support for most of AXP20X and AXP22X ADCs.
