Currently serdev core doesn't provide functions to retrieve common UART settings like data bits, stop bits or parity. This patch adds the interface to the core and the necessary implementation for serdev-ttyport.
It doesn't provide them because why do you need to know? The attached device should request the settings it needs and be done with it. Maybe some devices can support a number of settings and you could want negotiate the settings with the UART, though surely 8N1 is in that list. It's rare to see something that's not 8N1 from what I've seen. Rob
