This patch introduce new Cadence USBSS DRD driver to linux kernel. The Cadence USBSS DRD Controller is a highly configurable IP Core which can be instantiated as Dual-Role Device (DRD), Peripheral Only and Host Only (XHCI)configurations. The current driver has been validated with FPGA burned. We have support for PCIe bus, which is used on FPGA prototyping. The host side of USBSS-DRD controller is compliance with XHCI specification, so it works with standard XHCI Linux driver. The device side of USBSS DRD controller is compliant with XHCI. The architecture for device side is almost the same as for host side, and most of the XHCI specification can be used to understand how this controller operates. This controller and driver support Full Speed, Hight Speed, Supper Speed and Supper Speed Plus USB protocol. The prefix cdnsp used in driver has chosen by analogy to cdn3 driver. The last letter of this acronym means PLUS. The formal name of controller is USBSSP but it's to generic so I've decided to use CDNSP. The patch 1: adds support for DRD CDNSP. The patch 2: separates common code that can be reusable by cdnsp driver. The patch 3: moves reusable code to separate module. The patch 4: changes prefixes in reusable code from cdns3 to common cdns. The patch 5: adopts gadget_dev pointer in cdns structure to make possible use it in both drivers. The patches 6-8: add the main part of driver and has been intentionally split into 3 part. In my opinion such division should not affect understanding and reviewing the driver, and cause that main patch (7/8) is little smaller. Patch 6 introduces main header file for driver, 7 is the main part that implements all functionality of driver and 8 introduces tracepoints. The patch 9: Adds cdns3 prefixes to files related with USBSS driver. the patch 10: Adds USBSSP DRD IP driver entry to MAINTAINERS file. Changlog from v3: - added 'T' to MAINTAINERS file for CDNSP entry - updated common code with latest cdns3 fixes Changlog from v2: - removed not used pdev parameter from cdnsp_read/wite_64 functions - fixed incorrect value assigned to CDNSP_ENDPOINTS_NUM (32 -> 31) - replaced some constant value with CDNSP_ENDPOINTS_NUM macro - replaced 'true' with '1' in bits description in cdnsp-gadget.h file - fixed some typos - some other less important changes suggested by Peter Chen Changlog from v1: - updated common code to latest cdns3 driver - moved cdnsp driver files to cdns3 as sugested by Peter Chan - removed duplicate code from cdnsp_ep0_set_config function - added cdns3 prefixes to file related with USBSS driver - updated MAINTAINERS file - fixed issue with U1 - fixed issue with L1 - some less improtant changes sugested by Chunfeng Yun --- Pawel Laszczak (10): usb: cdns3: Add support for DRD CDNSP usb: cdns3: Split core.c into cdns3-plat and core.c file usb: cdns3: Moves reusable code to separate module usb: cdns3: Refactoring names in reusable code usb: cdns3: Changed type of gadget_dev in cdns structure usb: cdnsp: Device side header file for CDNSP driver usb: cdnsp: cdns3 Add main part of Cadence USBSSP DRD Driver usb: cdnsp: Add tracepoints for CDNSP driver usb: cdns3: Change file names for cdns3 driver.
