Hi Folks,
I have added the following
uart1_pins: pinmux_uart1_pins {
pinctrl-single,pins = <
0x170 0x30 /* (E15) uart0_rxd.uart0_rxd, PIN_INPUT |
MUX_MODE0 */
0x174 0x00 /* (E16) uart0_txd.uart0_txd, PIN_OUTPUT |
MUX_MODE0 */
>;
};
uart2_pins: pinmux_uart2_pins {
pinctrl-single,pins = <
0x180 0x30 /* (D16) uart1_rxd.uart1_rxd, PIN_INPUT |
MUX_MODE0 */
0x184 0x00 /* (D15) uart1_txd.uart1_txd, PIN_OUTPUT |
MUX_MODE0 */
>;
};
This worked for me
uart1: serial@44e09000 {
status = "okay";
pinctrl-names = "default";
pinctrl-0 = <&uart1_pins>;
};
uart2: serial@48022000 {
status = "okay";
pinctrl-names = "default";
pinctrl-0 = <&uart2_pins>;
};
