Thanks but (unfortunately) there've been 2 new versions since then.
Specifically, Benjamin NACK'ed this patch and requested we NOT include
device/manufacturer-specific compatible properties here. In fact, the
binding is still rather generic and IMO (and in Benjamin's opinion)
doesn't really need to be restricted to a specific device.

Please consider reviewing Benjamin's requests and my recent changes.
Benjamin has one small remaining comment on v4, and I plan to send the
5th (and final?) version once I'm confident you and Benjamin agree :)

Thanks,
Brian
