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.

staging: iio: ad2s1210: Fix SPI reading

2020-05-03T11:35:03+00:00

If the serial interface is used, the 8-bit address should be latched using
the rising edge of the WR/FSYNC signal.

This basically means that a CS change is required between the first byte
sent, and the second one.
This change splits the single-transfer transfer of 2 bytes into 2 transfers
with a single byte, and CS change in-between.

Note fixes tag is not accurate, but reflects a point beyond which there
are too many refactors to make backporting straight forward.

staging: iio: ad2s1210: Use device-managed API

2019-07-27T21:52:06+00:00

Use device-managed API to simplify the code.
The remove function is redundant now and can
be deleted.

staging: iio: ad2s1210: Remove platform data NULL check in probe

2019-06-17T20:06:43+00:00

The driver only needs to access GPIOs via GPIOLIB. And SPI can be
configured via device-tree or ACPI.

The platform data is a remnant from another time, and should not cause the
driver to error out during probing if it is NULL.
Also, it's not used.

staging: iio: add proper SPDX identifiers to remaining driver files

2019-04-03T09:10:17+00:00

There are a number of IIO staging drivers that do not have a proper SPDX
identifier on it.  So fix that up and at the same time, remove the "free
form" license text, as that's pretty much impossible for any tool to
parse.

This patch removes the license boilerplate text at the top of ad2s90.c

"WARNING: Missing or malformed SPDX-License-Identifier tag in line 1".
