This is the fourth version 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 peripheral This patch series is dependent on https://patchwork.kernel.org/cover/10966353/ --- v4: * patch 1 - no changes * corrected companion device search based on inputs from Thierry in patch 2 * removed unneeded dev variable and corrected value read in tegra210_utmi_port_reset function in patch 3 * dt binding doc and dtb files are corrected for alignments. Replaced extcon-usb-gpio with usb role switch. * Added support for USB role switch instead of extcon-usb-gpio and other minor comments as suggested by Chunfeng. * Enabled xudc driver as module instead of part of kernel in patch 8 --- V3: * Rebased patch 1 to top of tree. * Fixed bug in patch 2, where xudc interrupts dont get generated if USB host mode fails to probe. Moved fake port detection logic to generic xusb.c. fake usb port data is updated based on soc flag need_fake_usb3_port. * Added extra lines whereever necessary to make code more readable in patch 3 and 7. * dt binding doc is corrected for typos and extcon references. Also added details for clocks and removed xusb_ references to clock and power-domain names and accordingly patch 5 is updated. * removed avdd-pll-utmip-supply in patch 6, as its now part of padctl driver. * Patch 8 has no changes. --- 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.
