[PATCH v3 0/2] staging: iio: cdc: ad7746: add dt properties for capacitive channel setup

[Lucas Stankus]

This patch series aims to replace the platform_struct for the ad7746 driver
in favor of device tree bindings, creating the dt-binding documentation in
the process.

Since the header file was only used to define the struct and the excitation
level values, it was possible to remove the file entirely.

Changelog v2 -> v3:
- Add application reference note for the inverted EXCX dt bindings
- Replace macro with lookup table for setting the capacitive channel
  excitation voltage

    AD7746

[PATCH v3 2/2] staging: iio: cdc: ad7746: use dt for capacitive channel setup.

[Lucas Stankus]

Ditch platform_data fields in favor of device tree properties for
configuring EXCA and EXCB output pins and setting the capacitive channel
excitation level.

As this covers all current use cases for the platform_data struct, remove
ad7746.h header file since it's no longer needed.

This test is reversed.  I wonder if the static checkers can catch the
uninitialized variable bug...  It's probably better to write it as:

	if (device_property_read_u32(dev, "adi,excitation-vdd-permille",
				     &vdd_permille) {

So it matches the others.

Oops.  Sorry for the noise.  I was wrong on this.  I looked at the
device_property_read_bool() code instead of the device_property_read_u32().

It's disappointing that the returns are reversed.

Looks good to me.  Thanks!

Will leave time for Rob or anyone else to take a look etc before applying.

If I seem to have lost it then feel free to give me a poke in a few weeks
(it's happened a few times in the past :( 

Thanks,
