iio: resolver: ad2s1210: remove of_match_ptr()

2023-10-14T12:53:45+00:00

To be consistent with the rest of iio, remove of_match_ptr(). It does
not do anything useful here.

iio: resolver: ad2s1210: remove DRV_NAME macro

2023-10-14T12:53:45+00:00

The DRV_NAME macro is only used in one place in the ad2s1210 driver and
is not really needed so let's remove it.

iio: resolver: ad2s1210: move out of staging

This moves the ad2s1210 resolver driver out of staging. The driver has
been fixed up and is ready to graduate.

iio: resolver: ad2s90: Fix alignment for DMA safety

2022-06-14T10:53:19+00:00

____cacheline_aligned is an insufficient guarantee for non-coherent DMA
on platforms with 128 byte cachelines above L1.  Switch to the updated
IIO_DMA_MINALIGN definition.

Fixes tag is probably not where the issue was first introduced, but
is likely to be far beyond the point where anyone considers
backporting this fix.

iio:resolver:ad2s1200: Drop of_match_ptr protection

2020-09-21T17:41:31+00:00

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.

iio: remove explicit IIO device parent assignment

2020-06-14T10:49:59+00:00

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.
