The tsadc supports two reset methods: the cru and the otp_gpio. All boards except veyron and the evb simply use the cru-method and reuse the pin for something else. On the Firefly-RK3288 this is for example the case with the headphone. To prevent pinctrl-conflicts with these don't set the otp-gpio pinctrl by default but only in the boards using it.
