usb: uvc: Enumerate valid values for color matching

2023-03-11T12:57:37+00:00

[ Upstream commit e16cab9c1596e251761d2bfb5e1467950d616963 ] The color matching descriptors defined in the UVC Specification contain 3 fields with discrete numeric values representing particular settings. Enumerate those values so that later code setting them can be more readable.

usb: webcam: Invalid size of Processing Unit Descriptor

2021-03-18T08:02:27+00:00

According with USB Device Class Definition for Video Device the Processing Unit Descriptor bLength should be 12 (10 + bmControlSize), but it has 11. Invalid length caused that Processing Unit Descriptor Test Video form CV tool failed. To fix this issue patch adds bmVideoStandards into uvc_processing_unit_descriptor structure. The bmVideoStandards field was added in UVC 1.1 and it wasn't part of UVC 1.0a.

usb: ch9: Add USB 3.2 SSP attributes

2021-01-18T17:38:47+00:00

In preparation for USB 3.2 dual-lane support, add sublink speed attribute macros and enum usb_ssp_rate. A USB device that operates in SuperSpeed Plus may operate at different speed and lane count. These additional macros and enum values help specifying that.

USB: usbtmc: Add separate USBTMC_IOCTL_GET_SRQ_STB

2020-12-28T14:50:30+00:00

This new ioctl only returns the status byte (STB) that was originally sent by the device due to a service request (SRQ) condition. This ioctl checks the srq_asserted bit of the associated file descriptor. If set, the srq_asserted bit is reset and the cached STB with original SRQ information is returned. Otherwise the ioctl returns the error code ENOMSG. This ioctl is useful to support non USBTMC-488 compliant devices. Time sensitive applications can read the cached STB without incurring the cost of an urb transaction over the bus.

USB: usbtmc: Add USBTMC_IOCTL_GET_STB

2020-12-28T14:50:30+00:00

This new ioctl reads the status byte (STB) from the device and returns the STB unmodified to the application. The srq_asserted bit is not taken into account and not changed. This ioctl is useful to support non USBTMC-488 compliant devices.

USB: ch9: add "USB_" prefix in front of TEST defines

2020-06-24T13:01:24+00:00

For some reason, the TEST_ defines in the usb/ch9.h files did not have the USB_ prefix on it, making it a bit confusing when reading the file, as well as not the nicest thing to do in a uapi file. So fix that up and add the USB_ prefix on to them, and fix up all in-kernel usages. This included deleting the duplicate copy in the net2272.h file.

Several newer USB Device classes are not presently reported individually at /sys/kernel/debug/usb/devices, (reported as "unk."). This patch adds the following classes: 0fh (Personal Healthcare devices), 10h (USB Type-C combined Audio/Video devices) 11h (USB billboard), 12h (USB Type-C Bridge).

usb: raw-gadget: support stalling/halting/wedging endpoints

2020-05-14T09:30:18+00:00

Raw Gadget is currently unable to stall/halt/wedge gadget endpoints, which is required for proper emulation of certain USB classes. This patch adds a few more ioctls: - USB_RAW_IOCTL_EP0_STALL allows to stall control endpoint #0 when there's a pending setup request for it. - USB_RAW_IOCTL_SET/CLEAR_HALT/WEDGE allow to set/clear halt/wedge status on non-control non-isochronous endpoints.
