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.

iio: accel: Add bma150/smb380 support to bma180

2020-05-16T15:06:00+00:00

The bma150/smb380 are very similar to the bma023 but have a temperature
channel as well.

iio: accel: bma180: Rename center_temp to temp_offset

2020-05-16T15:04:38+00:00

The bma180 driver is being extended to support the bma150.
Its temperature channel is unsigned so the center_temp naming
no longer makes.

iio: accel: bma180: Add support for bma023

2020-05-16T15:03:31+00:00

The bma023 chip is similar enough to the bma180 and bma25x that the
same driver can support all of them.  The biggest differences are
the lack of a temperature channel and no low power but still working
mode.

The bma150 is a close relative of the bma023, but it does have a
temperature channel so support is not added for it.

iio: accel: bma180: Prepare for different reset values

2020-05-16T14:58:19+00:00

Some variants of the bma180 (eg bma023) have different reset
values.  In preparation for adding support for them, factor
out the reset value into the chip specific data.

iio: accel: bma180: BMA254 support

2019-12-30T16:29:09+00:00

This adds support for the BMA254 variant of this
accelerometer. The only difference for the simple IIO
driver is that values are 12 bit and the temperature
offset differs by 1 degree.

Whilst wildcards in naming are normally frowned upon:

The cases where I have labeled variables "25x" is where the
models are identical, so as to make things easier for people
that want to add support for BMA253 and BMA255.

iio: accel: bma180: Use explicit member assignment

2019-12-29T15:20:08+00:00

This uses the C99 explicit .member assignment for the
variant data in struct bma180_part_info. This makes it
easier to understand and add new variants.

This brings up the VDD and VDDIO regulators using the

Having a shorthand "dev" instead of &client->dev everywhere
