This patchset is composed with : - dt bindings of XUSB Pad Controller - dt bindings for XUSB device Driver - Tegra PHY driver for usb-role-switch and usb-phy - Tegra XUSB host mode driver to support OTG mode - Tegra XUSB device mode driver to use usb-phy and multi device mode - dts for XUSB pad controller - dts for xudc Tegra Pad controller driver register for role switch updates for OTG/peripheral capable USB ports and adds usb-phy for that corresponding USB ports. Host and Device mode drivers gets usb-phy from USB2's phy and registers notifier for role changes to perform corresponding role tasks. Tests done: - device mode support using micro-B USB cable connection between ubuntu host and DUT on micro-B port - host mode support by connecting pen-drive to micro USB port on DUT using micro-B OTG cable. - toggling between these 2 modes by hot plugging corresponding cables. DUT: Jetson-tx1, Jetson tx2. V2: - Updated usb-role-switch documentation for Padctl driver. - Update XUDC bindings doc as suggested by Rob. - Used standard error codes for error return. - Added of_platform_depopulate during error and driver removal. - Updated error variable during phy initialization in XUDC driver. - Updated Tegra210 soc dtb file as per changes to binding doc.
