2020-05-09usb: dwc3: select USB_ROLE_SWITCHArnd Bergmann1-0/+1
Calling into the role switch API requires that these functions are loaded, if they are in a loadable module and dwc3 itself is built-in, this produces a link error: drivers/usb/dwc3/drd.o: In function `dwc3_usb_role_switch_get': drd.c:(.text+0x26): undefined reference to `usb_role_switch_get_drvdata' drivers/usb/dwc3/drd.o: In function `dwc3_usb_role_switch_set': drd.c:(.text+0x97): undefined reference to `usb_role_switch_get_drvdata' drivers/usb/dwc3/drd.o: In function `dwc3_drd_init': drd.c:(.text+0x1ca7): undefined reference to `usb_role_switch_register' drivers/usb/dwc3/drd.o: In function `dwc3_drd_exit': drd.c:(.text+0x1e92): undefined reference to `usb_role_switch_unregister' Select the USB_ROLE_SWITCH symbol from dwc3 in that configuration.

2019-06-18usb: dwc3: qcom: Add support for booting with ACPILee Jones1-1/+1
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.

2019-05-03usb: dwc3: Add Amlogic G12A DWC3 glueNeil Armstrong1-0/+10
Adds support for Amlogic G12A USB Control Glue HW. The Amlogic G12A SoC Family embeds 2 USB Controllers : - a DWC3 IP configured as Host for USB2 and USB3 - a DWC2 IP configured as Peripheral USB2 Only A glue connects these both controllers to 2 USB2 PHYs, and optionnally to an USB3+PCIE Combo PHY shared with the PCIE controller. The Glue configures the UTMI 8bit interfaces for the USB2 PHYs, including routing of the OTG PHY between the DWC3 and DWC2 controllers, and setups the on-chip OTG mode selection for this PHY. This drivers supports the on-probe setup of the OTG mode, and manually via a debugfs interface. The IRQ mode change detect is yet to be added in a future patchset, mainly due to lack of hardware to validate on.

Some of its uses are described below resulting in need to have a separate glue driver instead of using dwc3-of-simple: - It exposes register interface to override vbus-override and lane0-pwr-present signals going to hardware. 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.

If dr_mode is "otg" then support dual role mode of operation. Currently this mode is only supported when an extcon handle is present in the dwc3 device tree node. This is needed to get the ID status events of the port. We're using a workqueue to manage the dual-role state transitions as the extcon notifier (dwc3_drd_notifier) is called in an atomic context by extcon_sync() and this doesn't go well with usb_del_gadget_udc() causing a lockdep and softirq warning.

2013-07-29usb: dwc3: make glue layers selectableFelipe Balbi1-0/+32
Glue layers are starting to have separate requirements. For example, OMAP's glue layer is starting to use extcon framework which no one else needs. In order to make it clear the proper dependencies, we are now allowing glue layers to be selectable so that each glue layer can list their own dependencies without messing with the core IP driver.

2012-08-31usb: gadget: get rid of USB_GADGET_{DUAL,SUPER}SPEEDMichal Nazarewicz1-2/+0
This commit removes USB_GADGET_DUALSPEED and USB_GADGET_SUPERSPEED Kconfig options. Since now kernel allows many UDC drivers to be compiled, those options may turn to no longer be valid. For instance, if someone decides to build UDC that supports super speed and UDC that supports high speed only, the latter will be "assumed" to support super speed since USB_GADGET_SUPERSPEED will be selected by the former. The test of whether CONFIG_USB_GADGET_*SPEED was defined was just an optimisation which removed otherwise dead code (ie. if UDC is not dual speed, there is no need to handle cases that can happen if speed is high). This commit removes those checks. Signed-off-by: Michal Nazarewicz <mina86@mina86.com> Signed-off-by: Felipe Balbi <balbi@ti.com>

2011-08-22usb: Introduce DesignWare USB3 DRD DriverFelipe Balbi1-0/+25
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.
