Not much help
there is a file i have found BB-BONE-AUDI-03-00A0.dts
that have other settings
fragment@0 {
target = <&am33xx_pinmux>;
__overlay__ {
bone_audio_cape_audio_pins: pinmux_bone_audio_cape_audio_pins {
pinctrl-single,pins = <
0x1ac 0x20 /* mcasp0_ahclkx, INPUT | MODE0 */
0x19c 0x22 /* mcasp0_axr2, INPUT | MODE2 */
0x194 0x20 /* mcasp0_fsx, INPUT | MODE0 */
0x198 0x08 /* mcasp0_axr0, OUTPUT | MODE0 */
0x190 0x20 /* mcasp0_aclkx, INPUT | MODE0 */
>;
};
};
};
seems closer but still backwards in my eye
