* media: v4l: Documentation: Raw Bayer formats are not RGB formatsSakari Ailus2019-08-157-1323/+1330
| | | | | | | | | | | | The raw Bayer formats have been listed under the label of RGB formats but in fact they're quite different. The latter are readily usable as such whereas the former require quite bit of image processing before useful. Split them into RGB and raw Bayer formats.

* media: v4l: Documentation: Serial busses use parallel mbus codesSakari Ailus2019-08-151-0/+8
| | | | | | | | | | | | | | | When the support for serial busses was introduced in V4L2, it was decided to use the existing parallel bus media bus pixel codes to describe them. While this was a practical choice at the time, it necessitates choosing which one of the many parallel mbus pixel codes to use, for on the serial busses these formats are effectively all equivalent. The practice has always been to use the pixel code that describes a bus that transfers a single sample per clock. Document this.

The list of FIELD values was outdated, so it was a bit confusing. The FIELD_NONE description said that 'The driver may also indicate this order when it cannot distinguish between V4L2_FIELD_TOP and V4L2_FIELD_BOTTOM'. This is false, NONE really means a full frame and userspace depends on that. So drop this line completely. There are no drivers that do this anyway. FIELD_TOP/BOTTOM/ALTERNATE indicate that the number of lines in the buffer are that of a field, not frame, so returning NONE here would cause huge problems.

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 formatsVivek Kasireddy2019-02-181-1/+169
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | 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.

This control directly corresponds to the chroma_qp_index_offset field of the h.264 picture parameter set.
