- * 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
