The USB ID pin on DRA7xx is connected via the gpio expander pcf8575. The interrupt line of the same is connected to the gpio 11 of bank 6. The following driver relies on the gpio interrupt to notify the actual ID pin values by which the dwc3 driver determines the HOST/Peripheral roles. These patches are on top of following merges. v3.11-rc3 dra7 baseport tree [1] , with balbi/next ,control-usb multi instance support [2], chanwoo/extcon-next, roger's patches for USB host adaptation[3],Laurent Pinchart's patch to Enable pcf857x GPIO expander for Device Tree[4] and pcf857x cleanup patch [5].
