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