| * 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 |
