The Broadcom 7211 has new functionality that allows some USB low speed side band signals, that go from the XHCI host controller to pins on the chip, to be remapped to use any GPIO pin instead of the limited set selectable by hardware. This can be done without changing the standard driver for the host controller. There is currently support for three USB signals, PWRON, VBUS_PRESENT and PWRFLT. This driver will allow the remapping of any of these three signals based on settings in the Device Tree node for the driver. The driver was written so that it could handle additional signals added in the future by just adding the correct properties to the DT node.
