Revert "usb: dwc3: Support EBC feature of DWC_usb31"

2024-02-09T10:26:08Z

This reverts commit 398aa9a7e77cf23c2a6f882ddd3dcd96f21771dc. The update to the gadget API to support EBC feature is incomplete. It's missing at least the following: * New usage documentation * Gadget capability check * Condition for the user to check how many and which endpoints can be used as "fifo_mode" * Description of how it can affect completed request (e.g. dwc3 won't update TRB on completion -- ie. how it can affect request's actual length report) Let's revert this until it's ready.

usb: dwc3: Support EBC feature of DWC_usb31

2024-01-04T15:00:41Z

Support configuration and use of bulk endpoints in the so-called EBC mode described in the DBC_usb31 databook (appendix E) Added a bit fifo_mode to usb_ep to indicate to the UDC driver that a specific endpoint is to operate in the EBC (or equivalent) mode when enabled Added macros for bits 15 and 14 of DEPCFG parameter 1 to indicate EBC mode and write back behaviour. These bits will be set to 1 when configuring an EBC endpoint as described in the programming guide Signed-off-by: Manan Aurora Link: https://lore.kernel.org/r/20231031034641.660606-1-maurora@google.com Signed-off-by: Greg Kroah-Hartman

usb: typec: tcpci: add vconn over current fault handling to maxim_core

2023-12-04T13:29:51Z

Add TCPC_FAULT_STATUS_VCONN_OC constant and corresponding mask definition. Maxim TCPC is capable of detecting VConn over current faults, so add fault to alert mask. When a Vconn over current fault is triggered, put the port in an error recovery state via tcpm_port_error_recovery.

usb: new quirk to reduce the SET_ADDRESS request timeout

2023-11-23T12:32:44Z

This patch introduces a new USB quirk, USB_QUIRK_SHORT_SET_ADDRESS_REQ_TIMEOUT, which modifies the timeout value for the SET_ADDRESS request. The standard timeout for USB request/command is 5000 ms, as recommended in the USB 3.2 specification (section 9.2.6.1). However, certain scenarios, such as connecting devices through an APTIV hub, can lead to timeout errors when the device enumerates as full speed initially and later switches to high speed during chirp negotiation. In such cases, USB analyzer logs reveal that the bus suspends for 5 seconds due to incorrect chirp parsing and resumes only after two consecutive timeout errors trigger a hub driver reset.

The newly introduced quirks provide the flexibility to align with a 3-second time limit, as required in specific contexts like automotive applications. By reducing the SET_ADDRESS request timeout to 500 ms, the system can respond more swiftly to errors, initiate rapid recovery, and ensure efficient device enumeration. This change is vital for scenarios where rapid smartphone enumeration and screen projection are essential.

usb: xhci: Add timeout argument in address_device USB HCD callback

2023-11-23T12:32:44Z

- The HCD address_device callback now accepts a user-defined timeout value in milliseconds, providing better control over command execution times. - The default timeout value for the address_device command has been set to 5000 ms, aligning with the USB 3.2 specification. However, this timeout can be adjusted as needed. - The xhci_setup_device function has been updated to accept the timeout value, allowing it to specify the maximum wait time for the command operation to complete. - The hub driver has also been updated to accommodate the newly added timeout parameter during the SET_ADDRESS request.

Revert "usb: phy: add usb phy notify port status API"

2023-11-06T13:47:36Z

This reverts commit a08799cf17c22375752abfad3b4a2b34b3acb287. The recently added Realtek PHY drivers depend on the new port status notification mechanism which was built on the deprecated USB PHY implementation and devicetree binding. Specifically, using these PHYs would require describing the very same PHY using both the generic "phy" property and the deprecated "usb-phy" property which is clearly wrong. We should not be building new functionality on top of the legacy USB PHY implementation even if it is currently stuck in some kind of transitional limbo. Revert the new notification interface which is broken by design.
