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.

These drivers don't use the driver_data member of struct i2c_device_id,
so don't explicitly initialize this member.
This prepares putting driver_data in an anonymous union which requires
either no initialization or named designators. But it's also a nice
cleanup on its own.
While add it, also remove commas after the sentinel entries.

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.

.probe_new() doesn't get the i2c_device_id * parameter, so determine
that explicitly in the probe function.

Letting the compiler remove these functions when the kernel is built
without CONFIG_PM_SLEEP support is simpler and less error prone than the
use of #ifdef based config guards.
Removing instances of this approach from IIO also stops them being
copied into new drivers.

This change converts the driver to use device-managed functions in the
probe function. The power-down call is handled now via a
devm_add_action_or_reset() hook, and then devm_iio_device_register() can be
used to register the IIO device.
The final aim here would be for IIO to export only the device-managed
functions of it's API. That's a long way to go and this a small step in
that direction.

This prevents use of this driver with ACPI via PRP0001 and is
an example of an anti pattern I'm trying to remove from IIO.
Hence drop from this driver.

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.

The equivalent of this is now done via macro magic when
the relevant register call is made. The actual structure

The IIO ABI specifies the name field of the IIO device as:
Description of the physical chip / device for device X.
Typically a part number.
The tmp007 driver currently uses the name of the parent device instead.
Change this to the part name to be in accordance with the ABI.

This patch adds support for TI TMP007 - 16 bit IR thermopile sensor with integrated Math engine.
Sensor takes care of calculating the object temperature with the help of calibrated constants stored in non-volatile memory,
thereby reducing the calculation overhead.
