Perhaps these should be 2 separate strings. Something like
'"nokia,n900-bt", "brcm,bcm2048"'. However, if they are in no way
compatible with the default version from the vendors, then just a single
string is fine, but it doesn't need to be aligned to the vendor
compatible string. So just "nokia,n900-bcm2048" or similar is fine.

Should be interrupt instead?

State direction and active state for gpios.

I want to see a common serial device binding doc before accepting any
device bindings. It's not going to say much initially other than devices
are child nodes of uarts. Perhaps something on baudrate settings.
