13 HSUART High-Speed Serial Port Support
14 -------------------------------------
16 The Apollo Lake UARTs are NS16550-compatible, with "high-speed" capability.
18 Baud rates beyond 115.2kbps (up to 3.6864Mbps) are supported, with additional
20 in turn outputs the baud master clock. The PLL is controlled by a per-UART
21 32-bit register called ``PRV_CLOCK_PARAMS`` (aka the ``PCP``), the format of
24 +--------+---------+--------+--------+
28 +--------+---------+--------+--------+
30 The resulting baud master clock frequency is ``(n/m)`` * master.
