2025-09-09media: i2c: ov6650: Drop unused driverLaurent Pinchart
The ov6650 driver was introduced in v2.6.37 to support the OMAP1-based Amstrad Delta video phone. The platform still has a board file in the kernel, but support for the camera was dropped in commit ce548396a433 ("media: mach-omap1: board-ams-delta.c: remove soc_camera dependencies") in v5.9. The driver has been unused since as it has received neither ACPI nor DT support. The ov6650 driver is one of the last sensor drivers calling clk_set_rate(). This is deprecated, and calls to the function are being removed to avoid cargo-cult. As the driver is unlikely to ever be used again, drop it instead of trying to avoid call clk_set_rate().

Instead of using hardwired video loopback limited to a single vivid instance, use the new 'Connected To' controls to only loopback if an HDMI or S-Video input is connected to another output, which can be in another vivid instance. Effectively this emulates connecting and disconnecting an HDMI/S-Video cable. The Loop Video control is dropped since it has now been replaced by the new 'Connected To' controls. The Display Present has also been dropped since it no longer fits.

"class:: toc-title" was a workaround for older Sphinx versions that are no longer supported. The canonical way to add a heading to the ToC is to use :caption:. Do that.

2023-10-07media: visl: use canonical ftrace pathRoss Zwisler
The canonical location for the tracefs filesystem is at /sys/kernel/tracing. But, from Documentation/trace/ftrace.rst: Before 4.1, all ftrace tracing control files were within the debugfs file system, which is typically located at /sys/kernel/debug/tracing. For backward compatibility, when mounting the debugfs file system, the tracefs file system will be automatically mounted at: /sys/kernel/debug/tracing Update the visl decoder driver documentation to use this tracefs path.
