usb: dwc2: add pci_device_id driver_data parse support

2023-08-22T12:49:12Z

The dwc2 driver has everything we need to run in PCI mode except for pci_device_id driver_data parse. With that to set Loongson dwc2 element and added identified as PCI_VENDOR_ID_LOONGSON and PCI_DEVICE_ID_LOONGSON_DWC2 in dwc2_pci_ids, the Loongson dwc2 controller will work.

usb: dwc2: platform: add support for utmi optional clock

2023-04-20T08:17:06Z

Add support for the utmi clock. It's needed on STM32MP15, when using the integrated full-speed PHY. This clock is an output of USBPHYC, but HS USBPHYC is not attached as PHY in this case: Full-Speed PHY is directly managed in dwc2 glue, through GGPIO register. Typical DT when using FS PHY &usbotg_hs { compatible = "st,stm32mp15-fsotg", "snps,dwc2"; pinctrl-names = "default"; pinctrl-0 = <&usbotg_hs_pins_a &usbotg_fs_dp_dm_pins_a>; vbus-supply = <&vbus_otg>; status = "okay"; }; In this configuration, USBPHYC clock output must be defined, so it can be properly enabled as a clock provider: clocks = <&rcc USBO_K>, <&usbphyc>; clock-names = "otg", "utmi"; Acked-by: Minas Harutyunyan Signed-off-by: Fabrice Gasnier Link: https://lore.kernel.org/r/20230414084137.1050487-4-fabrice.gasnier@foss.st.com Signed-off-by: Greg Kroah-Hartman

SPDX-License-Identifier have been added in commit 5fd54ace4721 ("USB: add SPDX identifiers to all remaining files in drivers/usb/") There is no point in keeping the now redundant license text.

USB: dwc2: Add OTG support for Ingenic SoCs.

2022-04-21T17:22:00Z

Add OTG support for the JZ4775 SoC, the JZ4780 SoC, the X1000 SoC, the X1600 SoC, the X1700 SoC, the X1830 SoC, and the X2000 SoC from Ingenic. Introduce support for disable Ingenic overcurrent detection, once selected, it enables the GOTGCTL register bits VbvalidOvEn and VbvalidOvVal to disable the VBUS overcurrent detection. This patch is derived from Dragan Čečavac (in the kernel 3.18.3 tree of CI20). It is very useful for the MIPS Creator CI20 (r1). Without this patch, OTG port of CI20 has a great probability to face overcurrent warning, which breaks the OTG functionality.

usb: dwc2: drd: fix soft connect when gadget is unconfigured

2022-02-17T15:10:21Z

When the gadget driver hasn't been (yet) configured, and the cable is connected to a HOST, the SFTDISCON gets cleared unconditionally, so the HOST tries to enumerate it. At the host side, this can result in a stuck USB port or worse. When getting lucky, some dmesg can be observed at the host side: new high-speed USB device number ... device descriptor read/64, error -110 Fix it in drd, by checking the enabled flag before calling dwc2_hsotg_core_connect(). It will be called later, once configured, by the normal flow: - udc_bind_to_driver - usb_gadget_connect - dwc2_hsotg_pullup - dwc2_hsotg_core_connect Fixes: 17f934024e84 ("usb: dwc2: override PHY input signals with usb role switch support") Cc: stable Signed-off-by: Fabrice Gasnier Link: https://lore.kernel.org/r/1644999135-13478-1-git-send-email-fabrice.gasnier@foss.st.com Signed-off-by: Greg Kroah-Hartman

When using usb-role-switch, while the usb role is not yet define (USB_ROLE_NONE), the user may want to configure the default mode to host or device. Use role-switch-default-mode for that purpose.
