Yeah, so things work fine for them right now but that can be improved by
changing the sequence of boot here. And that's what Amit is trying to do here.

Even if android builds this as a module later, things will continue to work but
that may not be the best performance/boot-time wise.

When I had a discussion about this with Amit earlier, I asked him to send
patches even if he doesn't have any performance numbers for it as this is a
platform driver and I find it okay for them to decide the boot sequence that
they think is the best :)
