2022-12-08usb: gadget: udc: drop obsolete dependencies on COMPILE_TESTJean Delvare1-2/+2
Since commit 0166dc11be91 ("of: make CONFIG_OF user selectable"), it is possible to test-build any driver which depends on OF on any architecture by explicitly selecting OF. Therefore depending on COMPILE_TEST as an alternative is no longer needed. It is actually better to always build such drivers with OF enabled, so that the test builds are closer to how each driver will actually be built on its intended target. Building them without OF may not test much as the compiler will optimize out potentially large parts of the code. In the worst case, this could even pop false positive warnings. Dropping COMPILE_TEST here improves the quality of our testing and avoids wasting time on non-existent issues.

2022-11-09usb: fotg210: Collect pieces of dual mode controllerLinus Walleij1-11/+0
The Faraday FOTG210 is a dual-mode OTG USB controller that can act as host, peripheral or both. To be able to probe from one hardware description and to follow the pattern of other dual- mode controllers such as MUSB or MTU3 we need to collect the two, currently completely separate drivers in the same directory. After this, users need to select the main symbol USB_FOTG210 and then each respective subdriver. We pave the road to compile both drivers into the same kernel and select the one we want to use at probe() time, and possibly add OTG support in the end. This patch doesn't do much more than create the new symbol and collect the drivers in one place. We also add a comment for the section of dual-mode controllers in the Kconfig file so people can see what these selections are about. Also add myself as maintainer as there has been little response on my patches to these drivers.

Pull ARM SoC platform updates from Arnd Bergmann: "The main change this time around is a cleanup of some of the oldest platforms based on the XScale and ARM9 CPU cores, which are between 10 and 20 years old. The Kendin/Micrel/Microchip KS8695, Winbond/Nuvoton W90x900 and Intel IOP33x/IOP13xx platforms are removed after we determined that nobody is using them any more. The TI Davinci and NXP LPC32xx platforms on the other hand are still in active use and are converted to the ARCH_MULTIPLATFORM build, meaning that we can compile a kernel that works on these along with most other ARMv5 platforms. Changes toward that goal are also merged for IOP32x, but additional work is needed to complete this. Patches for the remaining ARMv5 platforms have started but need more work and some testing. Support for the new ASpeed AST2600 gets added, this is based on the Cortex-A7 ARMv7 core, and is a newer version of the existing ARMv5 and ARMv6 chips in the same family. Other changes include a cleanup of the ST-Ericsson ux500 platform and the move of the TI Davinci platform to a new clocksource driver" [ The changes had marked INTEL_IOP_ADMA and USB_LPC32XX as being buildable on other platforms through COMPILE_TEST, but that causes new warnings that I most definitely do not want to see during the merge window as that could hide other issues.

2018-07-30usb: gadget: udc: renesas_usb3: Add register of usb role switchYoshihiro Shimoda1-0/+1
This patch adds role switch support for R-Car SoCs into the USB 3.0 peripheral driver. Some R-Car SoCs (e.g. R-Car H3) have USB 3.0 dual-role device controller which has the USB 3.0 xHCI host and Renesas USB 3.0 peripheral. Unfortunately, the mode change register (DRD_CON) contains the USB 3.0 peripheral controller side only. So, this renesas_usb3 driver manages the DRD_CON now. However, in peripheral mode, the host should stop. Also the host hardware needs to reinitialize its own registers when the mode changes from peripheral to host mode. Otherwise, the host cannot work correctly (e.g. detect a device as high-speed). To achieve this reinitialization by a driver, this driver also registers a role switch driver to manage the DRD_CON and get a device pointer of usb 3.0 host from "companion" property of OF. Then, when the usb role is changed, renesas_usb3_role_switch_set() will attach/release the xhci-plat driver to reinitialize the host hardware.

2018-05-15usb/gadget: Add driver for Aspeed SoC virtual hubBenjamin Herrenschmidt1-0/+2
The Aspeed BMC SoCs support a "virtual hub" function. It provides some HW support for a top-level USB2 hub behind which sit 5 gadget "ports". This driver adds support for the full functionality, emulating the hub standard requests and exposing 5 UDC gadget drivers corresponding to the ports. The hub itself has HW provided dedicated EP0 and EP1 (the latter for hub interrupts). It also has dedicated EP0s for each function. For other endpoints, there's a pool of 15 "generic" endpoints that are shared among the ports. The driver relies on my previous patch adding a "dispose" EP op to handle EP allocation between ports. EPs are allocated from the shared pool in the UDC "match_ep" callback and assigned to the UDC instance (added to the gadget ep_list). When the composite driver gets unbound, the new hook will allow the UDC to clean things up and return those EPs to the shared pool.

In most cases this other symbol is an architecture or platform specific symbol, or PCI.

New members are added to the UDC data structure for having platform device support along with extcon and phy support. Kconfig and Makefiles are modified to select platform driver for compilation.

Apart from your expected set of non-critical fixes, and other miscellaneous items, we have most of the changes in dwc3 (52.5%) with all other UDCs following with 34.8%. As for the actual changes, the most important of them are all the recent changes to reduce memory footprint of dwc3, bare minimum dual-role support on dwc3 and reworked endpoint count and initialization routines.

2017-04-11usb: gadget: udc: amd5536: split core and PCI layerRaviteja Garimella1-0/+18
This patch splits the amd5536udc driver into two -- one that does pci device registration and the other file that does the rest of the driver tasks like the gadget/ep ops etc for Synopsys UDC. This way of splitting helps in exporting core driver symbols which can be used by any other platform/pci driver that is written for the same Synopsys USB device controller. The current patch also includes a change in the Kconfig and Makefile. A new config option USB_SNP_CORE will be selected automatically when any one of the platform or pci driver for the same UDC is selected. Main changes: - amd5536udc_pci.c: PCI device registration is moved to this file. - amd5536udc.c: This file does rest of the core UDC fucntionality. 9 symbols are exported so as to be used by amd5536udc_pci.c. Module parameter definitions are moved to header file. - amd5536udc.h: Function declarations, module parameters definitions and few common header file includes are added to this file - Kconfig: New USB_SNP_CORE option is added which will be auto selected when any pci or platform driver config option for the UDC is chosen. - Makefile: Compiles the core and pci files separately.

2017-01-24usb: gadget: udc: atmel: Update endpoint allocation schemeCristian Birsan1-0/+14
This patch updates the usb endpoint allocation scheme for atmel usba driver to make sure all endpoints are allocated in order. This requirement comes from the datasheet of the controller. The allocation scheme is decided by fifo_mode parameter. For fifo_mode = 0 the driver tries to autoconfigure the endpoints fifo size. All other modes contain fixed configurations optimized for different purposes. The idea is somehow similar with the approach used on musb driver.

2016-03-04usb: fsl: drop USB_FSL_MPH_DR_OF Kconfig symbolArnd Bergmann1-1/+0
The USB_FSL_MPH_DR_OF symbol is used to ensure the code that interprets the DR device node is built whenever one of the two drivers (EHCI or UDC) for the platform is enabled. However, if CONFIG_USB is disabled and we only support gadget mode, this causes a Kconfig warning: warning: (USB_FSL_USB2) selects USB_FSL_MPH_DR_OF which has unmet direct dependencies (USB_SUPPORT && USB) We can avoid this warning by simply no longer using the symbol, and making sure we enter the drivers/usb/host/ directory when the UDC driver is enabled that needs the file, and then we use Makefile syntax to ensure the file is built-in if needed. There is currently a dependency on CONFIG_OF, but this is redundant, as we already know that this is set unconditionally for the platforms that use this driver.
