* 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
