Why This File Exists

Repeatable hardware-adapter layer. Deep compatibility for every driver is out of scope; this atlas records patterns, probe lifecycles, bus glue, IRQ/DMA usage, and links back to core abstractions.

config VIDEO_V4L2_I2C
	bool
	depends on I2C && VIDEO_DEV
	default y

config VIDEO_V4L2_SUBDEV_API
	bool
	depends on VIDEO_DEV && MEDIA_CONTROLLER
	help
	  Enables the V4L2 sub-device pad-level userspace API used to configure
	  video format, size and frame rate between hardware blocks.

	  This API is mostly used by camera interfaces in embedded platforms.

config VIDEO_ADV_DEBUG
	bool "Enable advanced debug functionality on V4L2 drivers"
	help
	  Say Y here to enable advanced debugging functionality on some
	  V4L devices.
	  In doubt, say N.

config VIDEO_FIXED_MINOR_RANGES
	bool "Enable old-style fixed minor ranges on drivers/video devices"
	help
	  Say Y here to enable the old-style fixed-range minor assignments.
	  Only useful if you rely on the old behavior and use mknod instead of udev.

	  When in doubt, say N.
