Extend the AD4000 series device tree documentation to also describe
PulSAR devices.
The single-channel series of PulSAR devices is similar to the AD4000 series
except PulSAR devices sample at slower rates and don't have a
configuration register. Because PulSAR devices don't have a configuration
register, they don't support all features of AD4000 devices and thus fewer
interfaces are provided to user space. Also, while AD4000 may have their
SDI pin connected to SPI host MOSI line, PulSAR SDI pin is never connected
to MOSI.
Some devices within the PulSAR series are just faster versions of others.
From fastest to slowest, AD7980, AD7988-5, AD7686, AD7685, and AD7988-1 are
all 16-bit pseudo-differential pin-for-pin compatible ADCs. Devices that
only vary on the sample rate are documented with a common fallback
compatible.
Signed-off-by: Marcelo Schmitt <marcelo.schmitt@analog.com>

Change log v4 -> v5
- Added const items for fallback compatibles.

Look, you have here enum for all single-compatible cases. Add all of
other cases here as well. That's the convention in 99% of bindings.

The ADC data is pushed to the IIO buffer along with timestamp but no
timestamp channel was provided to retried the time data.
Add a timestamp channel to provide sample capture time.

H Marcelo,
Given you are going to be spinning a v6 anyway, trivial comments inline.
Thanks,

Add a trailing ,
In theory we can add more channels after this.

As above. Trailing comma should be here.
The only exception to that is when we have a terminator entry (NULL or similar)
where we want to make it hard to add anything after it.

The SPI transfers for AD4020, AD4021, and AD4022 have slightly different
timing specifications. Use device specific timing constraints to set SPI
transfer parameters. While tweaking time constraints, remove time related
defines including unused AD4000_TQUIET1_NS.

The ADI PulSAR series of single-channel devices comprises differential and
pseudo-differential ADCs that don't require any input data from the host
controller. By not requiring a data input line, PulSAR devices can operate
with a 3-wire only data bus in some setups.
The AD4000 series and the single-channel PulSAR series of devices have
similar SPI transfer specifications and wiring configurations.
Single-channel PulSAR devices are slower than AD4000 and don't have a
configuration register. That taken into account, single-channel PulSARs can
be supported by the ad4000 driver without any increase in code complexity.
Extend the AD4000 driver to also support single-channel PulSAR devices.
