No, these are not allowed. You did not test your dts.

It does not look like you tested the DTS against bindings. Please run
`make dtbs_check W=1` (see
Documentation/devicetree/bindings/writing-schema.rst or
https://www.linaro.org/blog/tips-and-tricks-for-validating-devicetree-sources-with-the-devicetree-schema/
for instructions).

Drop, why do you need it? Do you see it anywhere else in the backlight
nodes in DTS?

Name all regulators regulator-n, where n is decimal number. Then order
the nodes by name.

Please confirm the status of dtbs_check for your board. I am pretty sure
it fails.
