Hi,

I think we request a full name here and as patch author.

please use a consistent comment style ... in the "/* foobar */" style

so this regulator controls all of those?

In that case maybe do it similarly to vcc1v8-s3 and use multiple labels
for the node - i.e. the line name leading to the consumer from the
schematics.

That way comparing schematics against the dts gets easier.

See
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/arch/arm64/boot/dts/rockchip/rk3328-rock64.dts#n40
for an example
