  Clock and supplies are external to IMX274 sensor and are dependent
on camera module design.

So, this patch moves them to required properties.

If these have been optional in the past I don't think we can start
requiring them now.

The framework will just give the driver a dummy regulator if one isn't
found.

One more comment.

Jacopo has been working on converting this to YAML format. Could you rebase
your patch on his? I believe he's still working on some changes. The
subject is "[PATCH v3] dt-bindings: media: imx274: Convert to json-schema".

These were added recently with my patches. So I hope should be ok to 
make them required as they are external to sensor

The bindings were added back in 2017, so they're not really recent.

Also made them required as they are external to sensor and also to use 
bulk_enable/disable APIs, devm_regulator_bulk_get()

does not use OPTIONAL_GET.

Sure, will keep them as optional and will rebase dt-bindings on 
json-schema patch
