[media] doc-rst: switch to new names for Full Screen/Aspect keys

2019-03-27T00:41:30+00:00

We defined better names for keys to activate full screen mode or
change aspect ratio (while keeping the existing keycodes to avoid
breaking userspace), so let's use them in the document.

extended-controls.rst: split up per control class

2019-02-18T19:55:41+00:00

The extended-controls.rst file had become too big. Split it up: each
control class reference gets its own rst file, and this file just
describes the Extended Control API.

Each control class reference is also moved up one level into the
table of contents to make it easier to find e.g. the codec control
reference.

Finally I rearranged the order so that all camera-related control
classes are grouped together, ditto for codec/jpeg and fm-rx/tx.

The ext-ctrls-codec.rst is still pretty big and it is a candidate
to split up further in the future, possibly per codec.

media: v4l: Add 32-bit packed YUV formats

2019-02-18T19:31:01+00:00

The formats added in this patch include:
 V4L2_PIX_FMT_AYUV32
 V4L2_PIX_FMT_XYUV32
 V4L2_PIX_FMT_VUYA32
 V4L2_PIX_FMT_VUYX32

These formats enable the trasmission of alpha channel data to other
drivers and userspace applications in addition to YUV data. For
example, buffers generated by drivers in one of these formats
can be used by the Weston compositor to display as a texture or
flipped directly onto the overlay planes with the help of a DRM
driver.

media: Documentation/media: rename "Codec Interface"

2019-01-25T20:54:18+00:00

The "Codec Interface" chapter is poorly named since codecs are just one
use-case of the Memory-to-Memory Interface. Rename it and clean up the
text a bit.

media: dev-effect.rst: remove unused Effect Interface chapter

2019-01-25T20:47:59+00:00

We never had an effect interface, and if you want to do such
things you use the mem2mem interface instead.

Just drop this from the spec.
