media: vimc: expand the names of vimc entity types

2022-07-15T13:42:14+00:00

When introducing the lens controller, it became apparent that the vimc
entity type names were hard to understand, e.g. vimc_len_type refers to the
lens. The names of the vimc entity types have been expanded to make the
code easier to understand. There is no functional change intended.

media: vimc: Add support for contiguous DMA buffers

2022-02-16T11:47:02+00:00

The vimc driver is used for testing purpose, and some test use cases
involve sharing buffers with a consumer device. Consumers often require
DMA contiguous memory, which vimc doesn't currently support. This leads
in the best case to usage of bounce buffers, which is very slow, and in
the worst case in a complete failure.

Add support for the dma-contig allocator in vimc to support those use
cases properly. The allocator is selected through a new "allocator"
module parameter, which defaults to vmalloc.

media: media/test-drivers: use vb2_video_unregister_device()

2020-08-28T13:05:40+00:00

Use vb2_video_unregister_device() to automatically stop streaming
at unregister time.

This avoids the use of vb2_queue_release() which should not be
called by drivers that set vdev->queue.

media: vimc: Make use of V4L2_CAP_IO_MC

Set the V4L2_CAP_IO_MC capability flag to report this vimc
inputs/outputs are controlled by the media graph.

media: vimc: cap: Report a colorspace

2020-04-29T10:02:30+00:00

The colorspace reported by a video nodes should not be
V4L2_COLORSPACE_DEFAULT. Instead a default colorspace should be picked
by the driver if V4L2_COLORSPACE_DEFAULT is given by userspace to
{G,S,TRY}_FMT.

The colorspace V4L2_COLORSPACE_SRGB is arbitrary chosen as the vimc
default format to report as it's used for most webcams.

media: media/test_drivers: rename to test-drivers

2020-04-16T08:38:31+00:00

We never use _ in directory names in the media subsystem, so
rename to test-drivers instead for consistency.

Also update MAINTAINERS with the new path.
