Please do not use "This commit/patch/change", but imperative mood. See
longer explanation here:
https://elixir.bootlin.com/linux/v5.17.1/source/Documentation/process/submitting-patches.rst#L95

A nit, subject: drop second/last, redundant "devicetree bindings". The
"dt-bindings" prefix is already stating that these are bindings.

Instead: "add Bosch FULL NAME OF THE DEVICE"

I don't understand why you mention above. It does not support interrupt,
just like it does not support AXI bus, 500 GPIOs etc. It suggests you
speak about driver, not hardware.

Just describe what this device is - like first sentence.

With some improvements here:

This is an automated instruction, just in case, because many review tags
are being ignored. If you know the process, you can skip it (please do
not feel offended by me posting it here - no bad intentions intended).
If you do not know the process, here is a short explanation:

Please add Acked-by/Reviewed-by/Tested-by tags when posting new
versions, under or above your Signed-off-by tag. Tag is "received", when
provided in a message replied to you on the mailing list. Tools like b4
can help here. However, there's no need to repost patches *only* to add
the tags. The upstream maintainer will do that for tags received on the
version they apply.
