anyone have any ideas on how to get the RT5350 UART working?
here is the error in the log.
[ 0.460000] pinctrl core: add 1 pinmux maps
[ 0.460000] rt2880-pinmux pinctrl.1: found group selector 2 for uartf

here is the DTS config for the uart.
palmbus@10000000 {
uart@500 {
status = "okay";
};
i2c@900 {
status = "okay";
};
gpio0: gpio@600 {
status = "okay";
};
gpio1: gpio@660 {
status = "okay";
};
};
pinctrl {
state_default: pinctrl0 {
gpio {
ralink,group = "i2c", "jtag";
ralink,function = "gpio";
};
uartf {
ralink,group = "uartf";
ralink,function = "uartf";
};
};
};
Any info/hints on this are greatly appreciated.
Thanks,
