Hmm... Can you use 'reg-fixed-voltage' platform device instead?

One example, although gone from upstream, but available in the tree, I can
point to is this:

  git log -p -- arch/x86/platform/intel-mid/device_libs/platform_bcm43xx.c

It uses constant structures, but I think you may dynamically generate the
necessary ones.

I can experiment with this, though one thing is we have no actual idea
what voltages these are supplying...it doesn't look like that matters
from drivers/regulator/fixed.c, but I'd have to try it to be sure.

I believe it is likely 1.8v. But I can check if I have the schematics of a
reference design for something like this.

Hmm... Have I got it correctly that we can't have ena_gpio && led_gpio together?

No, just that we can only have led_gpio if we also have ena_gpio (at
least that's the intention...)

Okay, perhaps then a comment above?
