[PATCH] media: dt-bindings: nxp,imx8mq-mipi-csi2: Fix example endpoint label typo

[Robby Cai]

The example in imx8mq-mipi-csi2.yaml uses imx8mm_mipi_csi_{in,out} endpoint
labels, which is confusing for an i.MX8MQ binding. Rename the labels to
imx8mq_mipi_csi_{in,out} for consistency.

Fixes: 37255747ecbd ("media: dt-bindings: media: document the nxp,imx8mq-mipi-csi2 receiver phy and controller")

Nothing to fix here. Otherwise explain the bug.

Drop the labels instead - they are not used.

This is just churn and for sure not a fix.

I think the label has value, it improves readability of the example by
making the purpose of the endpoints more explicit. I won't fight for it
though, I know it's hard to change your mind.

Then should not have imx8mq in the first place. The only information
coming here is that it is input endpoint. IMO it is close to obvious
from the opposite of "remote-endpoint = <&imx477_out>;" (if remote is
OUT, then this must be IN). But keeping the redundant data or actually
correcting wrong redundant data into correct redundant data, is still
undesirable. Such patterns then keep spreading to new code.

Best regards,
Krzysztof

Dropping the imx8mm_ prefix instead of renaming it is a good idea,
thanks for proposing it. As for the Fixes: tag, I don't see a need to
backport this, so I'd leave it out too.

Fixes is not only for backporting but indicating that there was a bug,
being fixed here. For example for stats. There was no bug, because DTS
example absolutely does not matter - it's example code - therefore
redundant incorrect information in label matters even less.
