I have a patch series of 26 patches to convert fixed and GPIO regulators to use only GPIO descriptors.
That is fine stuff for the next merge window (v4.17). But it'd be nice to get the preperatory work into gpiolib already now so we avoid cross-tree dependencies. These patches parses the quirky regulators that use nonstandard GPIO line names an line flags, and exposes a function to get a named GPIO line from a device tree node that does not have a corresponding Linux device.
