How to use UART0 and UAR1 at the same time on DM365?

Hello

I am trying to use UART0 and UART1.

UART0 is for just debug port which is currenty working well.

Now I am adding UART1 (GPIO34: RX, GPIO25: TX) to communicate with other device but I can't get it work.

I can see /dev/ttyS1

but on booting log message show there are two ports but it only enabed uart0.
====================================================
boot log
====================================================
Serial: 8250/16550 driver, 2 ports, IRQ sharing disabled
serial8250.0: ttyS0 at MMIO 0x1c20000 (irq = 40) is a 16550A
console [ttyS0] enabled
====================================================

Also cat /proc/tty/driver/serial show unknown device for UART1
====================================================
serinfo:1.0 driver revision:
0: uart:16550A mmio:0x01C20000 irq:40 tx:2593 rx:34 RTS|CTS|DTR|DSR
1: uart:unknown mmio:0x01C20400 irq:41
====================================================

I changed pin mux as follow in dm365.c

MUX_CFG(DM365, UART1_TXD, 3,   29,    3,    3,     false)   // GPIO 25 : UART1_TXD
MUX_CFG(DM365, UART1_RXD, 4,   14,    3,    3,  false)     // GPIO 34 : UART1_RXD

and changed in board-dm365-evm.c
static struct davinci_uart_config uart_config __initdata = {
 .enabled_uarts = (1 << 0) | (1 << 1),
};

What's am I missing?

Thank you for your help in advance.
