Where is the driver?
This ended up in spam folder, so you might need to fix up your setup
just like other folks in Mediatek did.

This looks incomplete. How does it bind? Further pieces also suggest you
send something incomplete.

I have now doubts whether you define generic regulators or quite
specific regulators you have on your board... Are the names used in the
device datasheet in register API description?

Drop the labels here and further. Why you do not have here any regular
constraints like min/max voltage?

Where do you explain the meaning of modes?

Empty node? What does it do?
