And just looking at my patch, I remember I wrote this a month or so ago, 
thought it had been checked - but a couple of changes didn't make it in:

1) "bluetoooth" is spelled "bluetooth"
2) The realtek compatible should be wrapped in a "#ifdef 
CONFIG_BT_HCIUART_RTL" as hci_h5 needs that to have the realtek links in

I'll make these changes in a few days, but leave this patch here - in 
case there are any other comments.

Would hope to get basic nod by next week (yes know bad time for people 
over Christmas), as its free time I have to do the device tree that 
needs these in ...

Regards,

David.
