USB: add missing SPDX lines to Kconfig and Makefiles There are a few remaining drivers/usb/ files that do not have SPDX identifiers in them, all of these are either Kconfig or Makefiles. Add the correct GPL-2.0 identifier to them to make scanning tools happy. Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

usb: Introduce DesignWare USB3 DRD Driver The DesignWare USB3 is a highly configurable IP Core which can be instantiated as Dual-Role Device (DRD), Peripheral Only and Host Only (XHCI) configurations. Several other parameters can be configured like amount of FIFO space, amount of TX and RX endpoints, amount of Host Interrupters, etc. The current driver has been validated with a virtual model of version 1.73a of that core and with an FPGA burned with version 1.83a of the DRD core. We have support for PCIe bus, which is used on FPGA prototyping, and for the OMAP5, more adaptation (or glue) layers can be easily added and the driver is half prepared to handle any possible configuration the HW engineer has chosen considering we have the information on one of the GHWPARAMS registers to do runtime checking of certain features. More runtime checks can, and should, be added in order to make this driver even more flexible with regards to number of endpoints, FIFO sizes, transfer types, etc. While this supports only the device side, for now, we will add support for Host side (xHCI - see the updated series Sebastian has sent [1]) and OTG after we have it all stabilized.

These must be updated in peripheral mode for DWC3 if vbus lines are not connected to hardware block. Otherwise RX termination in SS mode or DP pull-up is not applied by device controller. - pwr_events_irq_stat support to check if USB2 PHY is in L2 state before glue driver proceeds with suspend. - Support for wakeup interrupts lines that are asserted whenever there is any wakeup event on USB3 or USB2 bus. - Support to replace pip3 clock going to DWC3 with utmi clock for hardware configuration where SSPHY is not used with DWC3.

usb: dwc3: qcom: Add support for booting with ACPI In Linux, the DWC3 core exists as its own independent platform device. Thus when describing relationships in Device Tree, the current default boot configuration table option, the DWC3 core often resides as a child of the platform specific node. Both of which are given their own address space descriptions and the drivers can be mostly agnostic to each other. However, other Operating Systems have taken a more monolithic approach, which is evident in the configuration ACPI tables for the Qualcomm Snapdragon SDM850, where all DWC3 (core and platform) components are described under a single IO memory region. To ensure successful booting using the supplied ACPI tables, we need to devise a way to chop up the address regions provided and subsequently register the DWC3 core with the resultant information, which is precisely what this patch aims to achieve.

usb: Introduce DesignWare USB3 DRD Driver The DesignWare USB3 is a highly configurable IP Core which can be instantiated as Dual-Role Device (DRD), Peripheral Only and Host Only (XHCI) configurations. Several other parameters can be configured like amount of FIFO space, amount of TX and RX endpoints, amount of Host Interrupters, etc. The current driver has been validated with a virtual model of version 1.73a of that core and with an FPGA burned with version 1.83a of the DRD core. We have support for PCIe bus, which is used on FPGA prototyping, and for the OMAP5, more adaptation (or glue) layers can be easily added and the driver is half prepared to handle any possible configuration the HW engineer has chosen considering we have the information on one of the GHWPARAMS registers to do runtime checking of certain features. More runtime checks can, and should, be added in order to make this driver even more flexible with regards to number of endpoints, FIFO sizes, transfer types, etc. While this supports only the device side, for now, we will add support for Host side (xHCI - see the updated series Sebastian has sent [1]) and OTG after we have it all stabilized.
