of course you can , the operation maybe as follow:
1. prepare at least one irq resource to this device.
2. Config your EMIF interface , assigning a chip memmory space for this device.
3. Add some code to initial the device and add ports in linux kernel ,
first add a structure to meet the require resource for this device
static struct uart_port serial_platform_data = {
.membase = the pysical memory space start address for your device assigned
in EMIF
.mapbase = the virtual address of .membase , you must do a extern
ioremap() function to convert membase to mapbase forward.
.iotype = UPIO_MEM,
.irq = irq assign for
.uartclk = 27000000,
.regshift = 2,
.type = PORT_16550A,
.line = sequcece of serial ports on your Soc board
};
your may enable the device's ports as:
#ifdef CONFIG_SERIAL_8250
early_serial_setup(&serial_platform_data);
#endif

Subject: Asynchronous communication element(TL16C554A) driver
Hi,
I have a board with DM6446 Soc.
I want to use Asynchronous communication element (TL16C554A) on my board for
4 new UART ports.
The chip will be connected through EMIF of DM6446.
Does anybody know if the davinci linux driver is available for TL16C554A?
Thanks in advance,
Joyab
