-* ARM SBSA defined generic UART
-This UART uses a subset of the PL011 registers and consequently lives
-in the PL011 driver. It's baudrate and other communication parameters
-cannot be adjusted at runtime, so it lacks a clock specifier here.

-Required properties:
-- compatible: must be "arm,sbsa-uart"
-- reg: exactly one register range
-- interrupts: exactly one interrupt specifier
-- current-speed: the (fixed) baud rate set by the firmware
