iio: Drop Duplicated "mount-matrix" parameter

2021-06-03T17:24:13+00:00

All of the users of iio_read_mount_matrix() are using the very same
property name. Moreover, the property name is hard coded in the API
documentation.

Make this clear and avoid duplication now and in the future.

iio: core: move @clock_id from struct iio_dev to struct iio_dev_opaque

2021-05-17T12:54:21+00:00

There is already an acessor function used to access it, making this
move straight forward.

No reason any driver should ever need access to this field, so hide it.

This lock is only of interest to the IIO core, so make it only

iio: core: move @trig_readonly from struct iio_dev to struct iio_dev_opaque

2021-05-17T12:49:13+00:00

This is only set via the iio_trig_set_immutable() call and later used
by the IIO core so there is no benefit in drivers being able to access
it.

iio: core: move @driver_module from struct iio_dev to struct iio_dev_opaque

2021-05-17T12:49:13+00:00

Continuing move to hide internal elements from drivers, move this structure
element over.  It's only accessed from iio core files so this one was
straight forward and no accessor functions are needed.

iio: core: move @id from struct iio_dev to struct iio_dev_opaque

2021-05-17T12:49:13+00:00

Continuing from Alexandru Ardelean's introduction of the split between
driver modifiable fields and those that should only be set by the core.

This could have been done in two steps to make the actual move after
introducing iio_device_id() but there seemed limited point to that
given how mechanical the majority of the patch is.

Includes fixup from Alex for missing mxs-lradc-adc conversion.

iio: set default trig->dev.parent

2021-03-25T19:13:50+00:00

When allocated with [devm_]iio_trigger_alloc(), set trig device parent to
the device the trigger is allocated for by default.

It can always be reassigned in the probe routine.

Change iio_trigger_alloc() API to add the device pointer to be coherent
with devm_iio_trigger_alloc, using similar interface to
iio_device_alloc().
