Mircea Caprioru 77f6a23092 staging: iio: adc: ad7192: Add low_pass_3db_filter_frequency
By adding this option we are able to remove the sync3 field and dt binding.
When setting the required cutoff frequency we also determine the ADC
configuration for chop and sync filter.

Mircea Caprioru 4be27c2a18 staging: iio: adc: ad7192: Remove platform data
This patch removes the reference voltage entry from the platform_data
structure. This is no longer needed since the reference voltage is obtained
from the device tree. With this we also remove the entire ad7192.h file.

The undefined reference voltage warning is promoted to an error signaling a
problem with the device tree.

Greg Kroah-Hartman c55cc97a25 Second set of IIO device support, features, cleanups and minor fixes for 5.3.

 they can't wait for the merge window.
 
 New Device Support
 * adf4371
   - New driver + bindings.

Alexandru Ardelean 10dd571c66 iio: adis162xx: fix low-power docs & reports
All current ADIS162XX drivers have incorrect values defined via comments.
Also, when an error is reported the printed value is incorrect.

The functionality itself isn't affected, so it's not a critical issue.

And since the change is trivial, it was included in a single patch that
fixes these in one go. All values were correlated with the ones specified
in the data-sheets.

Mircea Caprioru 2b0d1c6f12 staging: iio: adc: ad7192: Use read_avail for available attributes
This patch removes the in_voltage-voltage_scale_available and
in_voltage_scale_available attributes. These are replaced with available
attributes added in info_mask_shared_by_type_available.

With this modification the iio core will be responsible with naming the
attributes thus removing the checkpatch warning related to
in_voltage-voltage_scale_available naming.

Marcelo Schmitt 57565828ad staging: iio: ad5933: change attributes to match ABI
Change device attributes' names to match ABI documentation. Names were
chosen such that they tend to be similar to existing ABI so it should
be easier to standardize them when necessary.

Renato Lui Geh 9fb27f807e staging: iio: ad7780: moving ad7780 out of staging
Move ad7780 ADC driver out of staging and into the mainline.

The ad7780 is a sigma-delta analog to digital converter. This driver provides
reading voltage values and status bits from both the ad778x and ad717x series.
Its interface also allows writing on the FILTER and GAIN GPIO pins on the
ad778x.

Renato Lui Geh 4812a14a78 staging:iio:ad7780: add chip ID values and mask
The ad7780 supports both the ad778x and ad717x families. Each chip has
a corresponding ID. This patch provides a mask for extracting ID values
from the status bits and also macros for the correct values for the
ad7170, ad7171, ad7780 and ad7781.

Renato Lui Geh 33e1f90204 staging: iio: ad7780: set pattern values and masks directly
The AD7780 driver contains status pattern bits designed for checking
whether serial transfers have been correctly performed. Pattern macros
were previously generated through bit fields. This patch sets good
pattern values directly and masks through GENMASK.

Renato Lui Geh 0ee6d5ebe1 staging: iio: ad7780: add filter reading to ad778x
This patch adds the new feature of reading the filter odr value for
ad778x chips. This value is stored in the chip's state struct whenever a
read or write call is performed on the chip's driver.

This feature requires sharing SAMP_FREQ. Since the ad717x does not have
a filter option, the driver only shares the relevant info mask for the
ad778x family.
