2023-06-20dt-bindings: usb: dwc3: Add interrupt-names property support for wakeup ↵Piyush Mehta1-3/+3
interrupt The hibernation feature enabled for Xilinx Versal NET SoC in DWC3 IP. As the DWC3 IP supports the hibernation feature, to handle the wakeup or hibernation interrupt, add host mode "wakeup" interrupt-names optional property in the binding schema to capture remote-wakeup and connect/ disconnect event in the hibernation state and increased maxItems to 4 for the interrupts and interrupt-names property. We have a dedicated IRQ line specifically for the hibernation feature. When the "wakeup" IRQ line is triggered, it initiates a hibernation interrupt, causing the system to wake up from the hibernation state.

strlcpy() reads the entire source buffer first. This read may exceed the destination size limit. This is both inefficient and can lead to linear read overflows if a source string is not NUL-terminated [1]. In an effort to remove strlcpy() completely [2], replace strlcpy() here with strscpy(). Direct replacement is safe here since return value of -errno is used to check for truncation instead of PAGE_SIZE.

This adds support for the UHBR (Ultra High Bit Rate) bandwidths introduced with DisplayPort 2.0 (and refined in 2.1). These can go up to 80 Gbit/s and their support is represent in additional bits in the DP IN capability. This updates the DisplayPort tunneling to support these new rates too.

This is new TMU mode introduced with the USB4 v2. This mode is simpler than the existing ones and allows all CL states as well. Enable this for all links where both side routers are v2 and keep the existing functionality for the v1 and earlier links. Currently only support the MedRes rate.

Intel Barlow Ridge is the first USB4 v2 controller from Intel. The controller exposes standard USB4 PCI class ID in typical configurations, however there is a way to configure it so that it uses a special class ID to allow using s different driver than the Windows inbox one. For this reason add the Barlow Ridge PCI ID to the Linux driver too so that the driver can attach regardless of the class ID.

2023-06-16thunderbolt: Reset USB4 v2 host routerMika Westerberg2-8/+50
USB4 v2 added a bit that can be used to reset the host router so we use this to trigger reset when the driver probes. This will reset the already connected topology as well but doing this simplifies things a lot if for instance the link is already set to asymmetric. We also add a module parameter to prevent this in case of problems. While there rename the REG_HOP_COUNT to REG_CAPS to match the USB4 spec naming better.

USB4 v2 bumps the per-lane speed up to 40 Gb/s. Also the lanes are always bonded which gives 80 Gb/s symmetric link (and 120/40 Gb/s asymmetric). This updates the speed and width of routers and XDomain connections to support the Gen 4 link. For now we keep the link as is even if it is already asymmetric.

2023-06-13usb: update the ctime as well when updating mtime after an ioctlJeff Layton1-8/+8
In general, POSIX requires that when the mtime is updated that the ctime be updated as well. Add the missing timestamp updates to the usb ioctls.

2023-06-13usb: core: add sysfs entry for usb device stateRoy Luo4-4/+57
Expose usb device state to userland as the information is useful in detecting non-compliant setups and diagnosing enumeration failures. For example: - End-to-end signal integrity issues: the device would fail port reset repeatedly and thus be stuck in POWERED state. - Charge-only cables (missing D+/D- lines): the device would never enter POWERED state as the HC would not see any pullup. What's the status quo? We do have error logs such as "Cannot enable. Maybe the USB cable is bad?" to flag potential setup issues, but there's no good way to expose them to userspace. Why add a sysfs entry in struct usb_port instead of struct usb_device? The struct usb_device is not device_add() to the system until it's in ADDRESS state hence we would miss the first two states. The struct usb_port is a better place to keep the information because its life cycle is longer than the struct usb_device that is attached to the port.

2023-06-13usb: common: usb-conn-gpio: Set last role to unknown before initial detectionPrashanth K5-0/+10
Currently if we bootup a device without cable connected, then usb-conn-gpio won't call set_role() since last_role is same as current role. This happens because during probe last_role gets initialised to zero. To avoid this, added a new constant in enum usb_role, last_role is set to USB_ROLE_UNKNOWN before performing initial detection. While at it, also handle default case for the usb_role switch in cdns3, intel-xhci-usb-role-switch & musb/jz4740 to avoid build warnings.
