* usb: dwc2: override PHY input signals with usb role switch supportAmelie Delaunay2020-10-021-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | This patch adds support for usb role switch to dwc2, by using overriding control of the PHY voltage valid and ID input signals. iddig signal (ID) can be overridden: - when setting GUSBCFG_FORCEHOSTMODE, iddig input pin is overridden with 1; - when setting GUSBCFG_FORCEDEVMODE, iddig input pin is overridden with 0. avalid/bvalid/vbusvalid signals can be overridden respectively with: - GOTGCTL_AVALOEN + GOTGCTL_AVALOVAL - GOTGCTL_BVALOEN + GOTGCTL_BVALOVAL - GOTGCTL_VBVALEN + GOTGCTL_VBVALOVAL It is possible to determine valid sessions thanks to usb role switch: - if USB_ROLE_NONE then !avalid && !bvalid && !vbusvalid - if USB_ROLE_DEVICE then !avalid && bvalid && vbusvalid - if USB_ROLE_HOST then avalid && !bvalid && vbusvalid Acked-by: Minas Harutyunyan <hminas@synopsys.com> Acked-by: Martin Blumenstingl <martin.blumenstingl@googlemail.com> Signed-off-by: Amelie Delaunay <amelie.delaunay@st.com> Signed-off-by: Felipe Balbi <balbi@kernel.org>
* usb: remove redundant 'default n' from Kconfig-sBartlomiej Zolnierkiewicz2019-05-211-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 'default n' is the default value for any bool or tristate Kconfig setting so there is no need to write it explicitly. Also since commit f467c5640c29 ("kconfig: only write '# CONFIG_FOO is not set' for visible symbols") the Kconfig behavior is the same regardless of 'default n' being present or not: ... One side effect of (and the main motivation for) this change is making the following two definitions behave exactly the same: config FOO bool config FOO bool default n With this change, neither of these will generate a '# CONFIG_FOO is not set' line (assuming FOO isn't selected/implied). That might make it clearer to people that a bare 'default n' is redundant. ...

* USB: add missing SPDX lines to Kconfig and MakefilesGreg Kroah-Hartman2019-01-221-0/+2
| | | | | | | | 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: add CONFIG_USB_PCI for system have both PCI HW and non-PCI based USB HWyuan linyu2017-03-171-1/+1
| | | | | | | | | | | | a lot of embeded system SOC (e.g. freescale T2080) have both PCI and USB modules. But USB module is controlled by registers directly, it have no relationship with PCI module. when say N here it will not build PCI related code in USB driver.

* USB: dwc2-usb: add USB_GADGET dependencyArnd Bergmann2016-06-291-0/+1
| | | | | | | | | | | | | | | | | | | | The driver selects NOP_USB_XCEIV, which can only be built-in if USB_GADGET is either disabled or also built-in, so with USB_DWC2_PCI=y and USB_GADGET=m, NOP_USB_XCEIV is also built-in and we get this link error: drivers/usb/built-in.o: In function `nop_set_peripheral': (text+0x1927c): undefined reference to `usb_gadget_vbus_connect' drivers/usb/built-in.o: In function `nop_gpio_vbus_thread': (text+0x197a0): undefined reference to `usb_gadget_vbus_connect' (text+0x19830): undefined reference to `usb_gadget_vbus_disconnect' This adds the same dependency for the dwc2 driver to avoid that broken configuration.

* usb: dwc2: remove dwc2_platform.koMian Yousaf Kaukab2015-04-291-8/+0
| | | | | | | | | | | | | As dwc2 pci module is now exporting dwc2 platform device, include platform.o in dwc2-y and remove USB_DWC2_PLATFORM configuration option. Driver will be built as two modules, dwc2.ko and dwc2_pci.ko. dwc2.ko is the new platform driver. Remove all EXPORT_SYMBOL_GPL as they are not needed any more.

* usb: dwc2: pci: Add device mode to the dwc2-pci driverJohn Youn2015-03-111-3/+4
| | | | | | | | | | | | The pci driver now registers a platform driver, like in dwc3, and lets its probe function do all the initialization. This allows it to account for changes to the platform driver that were not added to the pci driver. Also future changes to the probe function don't have to be duplicated. This also has the effect of adding device and DRD mode to the pci driver. Tested on the Synopsys HAPS PCIe platform.

* usb: dwc2: fix USB core dependenciesArnd Bergmann2015-01-301-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It is currently possible to configure the dwc2 driver as built-in when host mode or dual-role is enabled, but the USB core is a loadable module.

* usb: dwc2: Update Kconfig to support dual-roleDinh Nguyen2014-11-141-27/+39
| | | | | | | | | | | | Update DWC2 kconfig and makefile to support dual-role mode. The platform file will always get compiled for the case where the controller is directly connected to the CPU. So for loadable modules, dwc2.ko is built for host, peripheral, and dual-role mode. The PCI bus interface will be called dwc2_pci.ko and the platform interface module will be called dwc2_platform.ko.

* usb: dwc2/s3c-hsotg: move s3c-hsotg into dwc2 directoryDinh Nguyen2014-04-241-14/+47
| | | | | | | | | | | | | | | | | | | | | | | | Moves the s3c-hsotg driver into the dwc2 directory and uses the dwc2 defines in hw.h. Renames s3c-hsotg.c to gadget.c. NOTE: You can build both host and peripheral as a dynamically linked module, but be aware that if you insmod dwc2_gadget, then rmmod it, then insmod dwc2 and dwc2_platform for host mode, this will not work. As the step to rmmod dwc2_gadget.ko will turn off the clock to the USB IP. The dwc2 host driver currently does not look to turn on a clock yet. A patch to fix that will be coming soon.

* Move DWC2 driver out of stagingPaul Zimmerman2014-01-131-0/+53
The DWC2 driver should now be in good enough shape to move out of staging. I have stress tested it overnight on RPI running mass storage and Ethernet transfers in parallel, and for several days on our proprietary PCI-based platform.
