title: ARM SBSA UART

maintainers:
  - Andre Przywara <andre.przywara@arm.com>

description:
  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.
