This isn't that trivial so I'd like some device tree maintainer
input if possible.
For now I've backed out the driver from my tree (given timing we have
loads of time to sort this out!)
Anyhow, anyone device tree related able to take a look at this.
Adriana, btw these should be cc'd to the device tree maintainers in
the first place (now added).
