The first 5 integers <mux_reg conf_reg input_reg mux_val 11f3ff96e9SFrank Li input_val> are specified using a PIN_FUNC_ID macro, which can be found in 12f3ff96e9SFrank Li imx6ul-pinfunc.h under device tree source folder. The last integer CONFIG is 13f3ff96e9SFrank Li the pad setting value like pull-up on this pin.
