This is totally unreadable.  include/linux/pci_ids.h exists for a 
please use it.   At least the vendor should be in there.

If you want to define the device id with the same naming convention
but in the local source file, I won't object.

Looking back at the rest of the patch:
> +#define GET_64BIT(prop, i)     ((((u64) (prop)[(i)]) << 32) | 
> (prop)[(i)+1])

Please use the (new) helper of_read_number in prom.h.


PS: how about create instead of wrote in the subject?
