This is the second verion of series "Tegra XUSB gadget driver support" Patches 1-3 are phy driver changes to add support for device mode. Patches 4-7 are changes related to XUSB device mode controller driver. Patch 8 is to enable XUDC driver in defconfig Test Steps(USB 2.0): - Enable "USB Gadget precomposed configurations" in defconfig - Build, flash and boot Jetson TX1 - Connect Jetson TX1 and Ubuntu device using USB A to Micro B cable - After boot on Jetson TX1 terminal usb0 network device should be enumerated - Assign static ip to usb0 on Jetson TX1 and corresponding net device on ubuntu - Run ping test and transfer test(used scp) to check data transfer communication SS mode is verified by enabling Type A port as device Above patches are dependent on below patch for functional evaluation https://patchwork.ozlabs.org/patch/976332/ --- V2: * Patches 1-3 are new patches in this series, which splits unified features patch to speprated features and removes need of port-fake entry in DT. * Patch 4 is re-arragend dt-bindings patch which incorporates previous patch comments to sort DT entries alphabetically, addresses name changes and PM domain details added. * Patch 5-6 are re-arranged DT patches with major changes - sort entries alphabetically, and adds clock names. * Patch 7 is UDC driver tegra XUSB device mode controller with major changes - remove un-used module params, lockinng for device_mode flag, moving un-needed info logs to debug level, making changes feature flag dependent rather than SOC based macros and other error handling in probe. * Patch 8 has no changes.
