Ultra-wideband (UWB) is a short-range wireless communication protocol.

NXP has SR1XX family of UWB Subsystems (UWBS) devices. SR1XX SOCs
are FiRa Compliant. SR1XX SOCs are flash less devices and they need
Firmware Download on every device boot. More details on the SR1XX Family
can be found at https://www.nxp.com/products/:UWB-TRIMENSION

The sr1xx driver work the SR1XX Family of UWBS, and uses UWB Controller
Interface (UCI).  The corresponding details are available in the FiRa
Consortium Website (https://www.firaconsortium.org/).

This is a confusing tag... Why do you need it and what does it mean in
Linux kernel process?

No references to driver. Please describe here the title of the hardware.

The same. Additionally use proper white-spaces. Before every '('. After
every '.'.

This is wrong and does not make any sense. You also did not test the
bindings.

Please test them before submitting. No need to waste reviewers time for
basic automation tasks.

Also do not include any wildcards (1xx) but specific model name.

No need for alias.

No point of enabling this.

The indentation and look of it is unacceptable...

This check can fail if there are any dependencies. The base for a patch
series is generally the most recent rc1.

If you already ran 'make dt_binding_check' and didn't see the above
error(s), then make sure 'yamllint' is installed and dt-schema is up to
date:

pip3 install dtschema --upgrade

Please check and re-submit.
