According to latest schematics [1], GPIO_1/VBUSDET on TPS659038 is tied to AM57x GPIO4_21. We can use that as a VBUS interrupt, instead of relying on PMIC's VBUS interrupts which don't seem to be firing on x15 at all.
A follow up patch will add support for using this GPIO-based interrupt mechanism for notifying about VBUS.
