I managed to write a more or less complete implementation based on your code (although I think it was mostly rewritten). Can you have a look at the PR here: https://github.com/apache/incubator-nuttx/pull/2717 ? (I couldn't find your github username).
I haven't tested this yet, as I'm unsure about GPIO handling (don't want to fry any pins or the I2C device).
