Practically every Android has this, and those are irrelevant from a
driver's POV.

The Android graphics stack is roughly:
 - libEGL drivers - mesa vs proprietary solutions.
 - HAL(glue) - *gralloc* and *hwcomposer*.
 - Kernel + modules.

Although they should be mostly identical independent of the Android flavour.

I feel that you're leaning towards "getting it into some Android, to be
used/tested", whereas I'm thinking at "get it upstream, and spread the
word so that Androids can pick it up".

Integration can be a pain sometimes, so I'd guess a quick email towards
Android X, Y and Z to get the feel might be nice.

Something like "I'm doing GSoC about... Can we get someone to help out
during the integration with your project ?"
