Hi Freescale,
We are using UART2 on imx6 with hardware flow control to communicate with gps module.
The hardware pin connection now is:

MX6Q_PAD_SD3_DAT4__UART2_RXD ----------- GPS TXD
MX6Q_PAD_SD3_DAT5__UART2_TXD ----------- GPS RXD
MX6Q_PAD_SD3_CLK__UART2_RTS  ----------- GPS CTS
MX6Q_PAD_SD3_CMD__UART2_CTS  ----------- GPS RTS

But as we read in imx6 ref manual and some web pages, should the connection be as below?

UART2_RXD ----------- GPS TXD
UART2_TXD ----------- GPS RXD
UART2_CTS ----------- GPS CTS
UART2_RTS ----------- GPS RTS

Is that right? If that is right, can we config the uart pins by software as below to handle this?

MX6Q_PAD_SD3_DAT4__UART2_RXD ----------- GPS TXD
MX6Q_PAD_SD3_DAT5__UART2_TXD ----------- GPS RXD
MX6Q_PAD_SD3_CLK__UART2_CTS  ----------- GPS CTS
MX6Q_PAD_SD3_CMD__UART2_RTS  ----------- GPS RTS

Thanks and best regard.
