Why do you need an output name here?
Also, where does this clock come from? Is it an oscillator on the board?

For all of these regulators, please put "regular-" as a prefix for the
node names.

Conor.

The output name can be unnecessary.

This clock come from imx219, not the VisionFive 2 board.

If the camera is not on the visionfive 2 board, why are you adding this
to visionfive-2.dtsi?

It seems that I need to use dtso. Right?

Yes. FWIW, the same comments as applied for the sound card Walker tried
to add applies here too, unless this ships with the boards:

I figure this is a similar case as that?

Yes, I will drop the IMX219 node in next version.
