AM3359: UART junk data

Part Number: AM3359

Sir,

UART 0 & UART 1 of the am3359 is working properly. but the UART 2 & UART 3 giving junk data.

Here i given the device tree which consist of the UART2 & UART3 pin mux configuration,

whether i have to change this configuration ?? if its kindly share the mode & pin no for am3359 UART2 & UART3

 uart2_pins: pinmux_uart2 {
                pinctrl-single,pins = <
                        0x12C (PIN_INPUT_PULLUP | MUX_MODE1)    /* mii1_tx_clk.uart2_rxd */
                        0x130 (PIN_OUTPUT_PULLDOWN | MUX_MODE1) /* mii1_rx_clk.uart2_txd */
                >;
        };

        uart3_pins: pinmux_uart3 {
                pinctrl-single,pins = <
                        0x134 (PIN_INPUT_PULLUP | MUX_MODE1)    /* mii1_rxd3.uart3_rxd */
                        0x138 (PIN_OUTPUT_PULLDOWN | MUX_MODE1) /* mii1_rxd2.uart3_txd */
                >;
        };

&uart2 {
        pinctrl-names = "default";
        pinctrl-0 = <&uart2_pins>;
        status = "okay";
};

&uart3 {
        pinctrl-names = "default";
        pinctrl-0 = <&uart3_pins>;
        status = "okay";
};

thanks
