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.

Missing signoff here.

depends on ARM || ARM64 || COMPILE_TEST?
