Add VTM bindings documentation. In the Voltage Thermal
Management Module(VTM), K3 J72XX supplies a voltage
reference and a temperature sensor feature that are gathered in the band
gap voltage and temperature sensor (VBGAPTS) module. The band
gap provides current and voltage reference for its internal
circuits and other analog IP blocks. The analog-to-digital
converter (ADC) produces an output value that is proportional
to the silicon temperature.

Eh, I wished people used automatically scripts/get_maintainers.pl, so
there will be no need to Cc someone. It's actually a bit weird because I
was reviewing v6...

In any case this misses all the review-tags, so I don't know what we are
supposed to do here.


Keerthy,
Please add Acked-by/Reviewed-by tags when posting new versions. However,
there's no need to repost patches *only* to add the tags. The upstream
maintainer will do that for acks received on the version they apply.

https://elixir.bootlin.com/linux/v5.13/source/Documentation/process/submitting-patches.rst#L543

If a tag was not added on purpose, please state why and what changed.

No items, you have only one item.
