There is one dependency patch: "regulator: core: Provide a dummy regulator with full constraints".
From the dependency patch, we can see that using regulator_get_optional() instead can resovle the problem you descripted above.
When or will this dependency patch be merged into the -next tree ?
That patch is already in mainline.
I'd expect to see a commit description that describes how the driver currently tries to handle this, why it doesn't work and how the patch fixes it.
The SGTL5000 requires 2 external power supplies: VDDA and VDDIO. An optional third external power supply VDDD may be provided externally
You need to put your working through of this stuff in the commit message.
