[PATCH] dt-bindings: iio: accel: adi,adis16201: add adis16203 compatible

[Shehryar Ahmad]

The ADIS16203 has the same external interface as the already
documented ADIS16201/ADIS16209, for the properties covered by this
binding (compatible/reg, the DIO-based interrupt pin, and VDD
supply), verified by datasheets Table 5, Pin Function Descriptions,
in the respective Analog Devices datasheets. Some Auxiliary pins
differ (e.g. adis16209 marks a few pins DNC where adis16201/adis16203
use them as AUX COM), but these are not represented in this binding.
Add adis16203 to the existing enum rather than creating a separate
file.

Tested with checkpatch.pl --strict and dt_binding_check; both pass
with no warnings.

Three prior attempts to document this part are visible on the
mailing list, all as separate files, each redirected toward this
existing binding approach instead: Saalim Quadri, March 2025 [2],
and Sheng Kun Chang, April 2026 [3]. See below for Jonathan
Cameron's earlier, related attempt [1].

A richer version adding reset-gpios and a second interrupt
(interrupt-names: dio0/dio1) was proposed by Jonathan Cameron in
2023 [1]. I tested the same additions locally for all three
parts; checkpatch and dt_binding_check both pass. It is not
included here, as it hasn't been verified against any real board
dts file, and none in-tree currently reference adis16201,
adis16203, or adis16209. Can send that as a follow-up if
wanted.

This is assumed, no need to record it forever in the commit.

Thanks for the history. It should be after the '---' so it too is not 
recorded in the commit.

Key thing here is that we generally don't take bindings for drivers
that are in staging and adis16203 remains there.

This patch looks good for when/if the driver is moved out of
staging.  There have been various series on list for that so
perhaps ask those authors what current status is (just reply
to that series).

e.g. 

https://lore.kernel.org/linux-iio/20260401162458.88110-1-nothingchang@mirrorstack.ai/

Which is the parent of the last link below and I think the last of
various attempts to do this.
