+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.
