Is there any reason not to consider submitting this as a TTY driver now - are there known problems other than the issues with ACPI in general (I've not reviewed the code at all)? The ACPI binding in this case seems particularly safe since it's a purposely basic and unconfigurable IP. I guess we may want to consider handoff to the full pl011 driver at some point but there's a bunch of stuff with clocks to worry about before then. > > Signed-off-by: Graeme Gregory <[email protected]> > --- Missing signoff here. > +config SBSAUART_TTY > + tristate "SBSA UART TTY Driver" > + help > + Console and system TTY driver for the SBSA UART which is defined > + in the Server Base System Architecure document for ARM64 servers. > + depends on ARM || ARM64 || COMPILE_TEST?
