This affects also at least Client (which I'm using). Also if you add new blob, there should be also one for RS485 (there is a GPIO to select between RS232/RS485). > Andrew wrote: > > I was going to take Aaro Koskinen patches, since they have Tested-by: > > etc. > > > > How about you ask Aaro to add the comment? I can add more verbose comments to mainline kernel .dts on how to enable serial port, and how to select between rs232/485. Andrew, do you want me to resend the current patches, or can it be done with an incremental patch? However, Debian probably needs to provide its own documentation how to modify the .dtb (probably some example how to convert the dtb to source with dtc, then how to do the modifications, and compile the source back to dtb).
