main_mcasp2_pins_default: main-mcasp2-default-pins {
pinctrl-single,pins = <
AM62X_IOPAD(0x178, PIN_INPUT, 2) /* (AC20) MCASP2_ACLKX */
AM62X_IOPAD(0x174, PIN_INPUT, 2) /* (AD21) MCASP2_AFSX */
AM62X_IOPAD(0x18c, PIN_OUTPUT, 2) /* (AC21) MCASP2_AXR0 */
AM62X_IOPAD(0x094, PIN_INPUT, 3) /* (N20) MCASP2_AXR12 */
>;
};

&mcasp2 {
status = "okay";
#sound-dai-cells = <0>;

pinctrl-names = "default";
pinctrl-0 = <&main_mcasp2_pins_default>;

op-mode = <0>; /* MCASP_IIS_MODE */
tdm-slots = <2>;

serial-dir = < /* 0: INACTIVE, 1: TX, 2: RX */
