The above either misses a group number or an uart number. We need
pinctrl_uart<uartno>_<groupno>
Also this doesn't scale very good. For boards without RTS/CTS we would have
to add a completely different group. For the FEC I've seen different
groups with a dozen pins each which differ in only a single pin.
I therefore suggest (and Shawn acked the general idea already) to
do this:
pinctrl_uart1_1: uart1-1 {
fsl,pins = <
MX27_PAD_UART1_TXD__UART1_TXD 0x0
MX27_PAD_UART1_RXD__UART1_RXD 0x0
>;
};
pinctrl_uart1_rtscts_1: uart1-rtscts-1 {
fsl,pins = <
MX27_PAD_UART1_CTS__UART1_CTS 0x0
MX27_PAD_UART1_RTS__UART1_RTS 0x0
>;
};
