Comment (by lsoltero):
still having the issue on CC r43400. Trying to get the serial port
working on an AsiaRF AWM002 eval board with RT5350.
here is the dts file.
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 = "pcm uartf";
};
};
};
here is the output from dmesg showing the same error as above.
