It does not features a USB overcurrent pin as GPIO, thus this pin needs to be routed in PIO controller to fixed 1 (by writing 1 to SYS_IOMUX_CFGSAIF__SYSCFG_FMUX_32[22:16]). I think this kind of situation needs to be considered as part of DT binding. BTW if you have any difficulty refactoring the DT binding to standard pinconf one, I am free to provide help.
