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 for Jetson TX1 and TX2 - dts for Jetson-TK1 - dts for Jetson-Nano 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. Order of merging Patches: Please merge DT changes first followed Tegra PHY driver changes and then USB driver changes. Tests done: - device mode support using micro-B USB cable connection between ubuntu host and DUT on micro-AB port - host mode support by connecting pen-drive to micro-AB USB port on DUT using standard-A to micro-A converter. - toggling between these 2 modes by hot plugging corresponding cables. DUT: Jetson-tx1, Jetson tx2, Jetson Nano(device mode test only). V5: - Jetson Nano DT changes are added in the series - Removed select USB_ROLE_SWITCH from Kconfig in the change corresponding to removal off role switch support from XUDC driver. V4: - Owner info is updated to port->dev for which USB role switch is used. - Updated function name in logs, unsigned int usage as per comments. - usb_phy_event is used instead of usb_role to detect role changes as notifier arguments of usb-phy is used for charging current updates. - Added ACKed-by info for corresponding patches. - Jetson TK1 DT changes added to remove USB2-0 port from padctl node. V3: - Port and cable names updated in "Tests done" section of cover letter as per JC inputs. - Fixed arguments allignments in USB padctl driver. - Padctl driver aborts if usb-role-switch is not present in dt for peripheral/otg roles. - Added Reviewed and ACKed details for corresponding patches. 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.
