1* ARM SBSA defined generic UART 2This UART uses a subset of the PL011 registers and consequently lives 3in the PL011 driver. It's baudrate and other communication parameters 4cannot be adjusted at runtime, so it lacks a clock specifier here. 5 6Required properties: 7- compatible: must be "arm,sbsa-uart" 8- reg: exactly one register range 9- interrupts: exactly one interrupt specifier 10- current-speed: the (fixed) baud rate set by the firmware 11
