I.MX How configure the Uart port

[Saenghee]

Dear NXP

We use below pins for uart. 

1. How configure the Uart kernel drv? (Kernel config, Dts configure...)

2. How to config below pins for Uart purpose pin?(dts config)

 ENET2_RX_ER support UART RTS function ? (it will connect BT UART CTS)

 ENET2_TX_CLK support UART CTS function?(it will connect BT UART RTS)

 ENET2_TX_DATA1 support UART TXD function?(it will connect BT UART RXD)

 ENET2_TX_EN support UART RXD function? (it will connect BT UART TXD)

3. How to set the tty port num? or Which tty port it be used?

I use IMX6ULLCEC . It be needed to porting the Bluetooth.

This uart will use for bluetooth interface.
