Alexandre Belloni 649ef114a0 iio:pressure:ms5637: add ms5803 support
The ms5803 is very similar to the ms5805 but has less resolution options
and has the 128bit PROM layout.

Alexandre Belloni 8c125f5f32 iio:pressure:ms5637: introduce hardware differentiation
Some sensors in the ms58xx family have a different PROM length and a
different number of available resolution. introduce struct ms_tp_hw_data to
handle those differences.

Jonathan Cameron 444f5f854b iio:pressure:ms5637: Drop of_match_ptr protection
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.

Alexandru Ardelean d3be83244c iio: remove explicit IIO device parent assignment
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.

Jonathan Cameron 6a15fef2cb iio:pressure: drop assign iio_info.driver_module and iio_trigger_ops.owner
The equivalent of both of these are now done via macro magic when
the relevant register calls are made.  The actual structure
elements will shortly go away.

Javier Martinez Canillas cdd469ad9e iio: Export I2C module alias information
The I2C drivers have an i2c_device_id array but that information isn't
exported to the modules using the MODULE_DEVICE_TABLE() macro. So the
modules autoloading won't work if the I2C device is registered using
OF or legacy board files due missing alias information in the modules.

The issue was found using Kieran Bingham's coccinelle semantic patch:
