+ Xilinx uart 16550 device registers are compatible with all standard
16540
+ and 16550 UARTs.

+ Required properties:
+ - current-speed : Baud rate of uart.
+ - clock-frequency : Baud rate generator reference clock. May be driven
+ by OPB_Clk (100 MHz).
+ - reg-shift : registers offset shift (standard uart_port field).
+ Property is optional if regshift is zero.

Xilinx hwicap devices provide access to the configuration logic
of the FPGA through the Internal Configuration Access Port
