0001 * ARM SBSA defined generic UART
0002 This UART uses a subset of the PL011 registers and consequently lives
0003 in the PL011 driver. It's baudrate and other communication parameters
0004 cannot be adjusted at runtime, so it lacks a clock specifier here.
0005
0006 Required properties:
0007 - compatible: must be "arm,sbsa-uart"
0008 - reg: exactly one register range
0009 - interrupts: exactly one interrupt specifier
0010 - current-speed: the (fixed) baud rate set by the firmware
