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.

since v1:

- Add description for raw Bayer formats

- Fix reference clash (rename _pixfmt-rgb to _pixfmt-bayer in
  pixfmt-bayer.rst)

- Remove _rgb-formats: and refer to _pixfmt-rgb: instead. Same for
  _rgb-formats-deprecated.

+Description
+===========
+
+The raw Bayer formats are used by image sensors before much if any processing is
+performed on the image. The formats contain green, red and blue components, with
+alternating lines of red and green, and blue and green pixels in different
+orders. See also `the Wikipedia article on Bayer filter
+<https://en.wikipedia.org/wiki/Bayer_filter>`__.

-.. note:: Bit 7 is the most significant bit.
-
-The usage and value of the alpha bits (a) in the ARGB and ABGR formats
-(collectively referred to as alpha formats) depend on the device type
-and hardware operation. :ref:`Capture <capture>` devices (including
-capture queues of mem-to-mem devices) fill the alpha component in
-memory. When the device outputs an alpha channel the alpha component
-will have a meaningful value. Otherwise, when the device doesn't output
-an alpha channel but can set the alpha bit to a user-configurable value,
-the :ref:`V4L2_CID_ALPHA_COMPONENT <v4l2-alpha-component>` control
-is used to specify that alpha value, and the alpha component of all
-pixels will be set to the value specified by that control. Otherwise a
-corresponding format without an alpha component (XRGB or XBGR) must be
-used instead of an alpha format.
-
-:ref:`Output <output>` devices (including output queues of mem-to-mem
-devices and :ref:`video output overlay <osd>` devices) read the alpha
-component from memory. When the device processes the alpha channel the
-alpha component must be filled with meaningful values by applications.
-Otherwise a corresponding format without an alpha component (XRGB or
-XBGR) must be used instead of an alpha format.
-
-The XRGB and XBGR formats contain undefined bits (-). Applications,
-devices and drivers must ignore those bits, for both
-:ref:`capture` and :ref:`output` devices.

+These formats are designed to match the pixel formats of typical PC
+graphics frame buffers. They occupy 8, 16, 24 or 32 bits per pixel.
+These are all packed-pixel formats, meaning all the data for a pixel lie
+next to each other in memory.

+.. note:: Bit 7 is the most significant bit.
+
+The usage and value of the alpha bits (a) in the ARGB and ABGR formats
+(collectively referred to as alpha formats) depend on the device type
+and hardware operation. :ref:`Capture <capture>` devices (including
+capture queues of mem-to-mem devices) fill the alpha component in
+memory. When the device outputs an alpha channel the alpha component
+will have a meaningful value. Otherwise, when the device doesn't output
+an alpha channel but can set the alpha bit to a user-configurable value,
+the :ref:`V4L2_CID_ALPHA_COMPONENT <v4l2-alpha-component>` control
+is used to specify that alpha value, and the alpha component of all
+pixels will be set to the value specified by that control. Otherwise a
+corresponding format without an alpha component (XRGB or XBGR) must be
+used instead of an alpha format.
+
+:ref:`Output <output>` devices (including output queues of mem-to-mem
+devices and :ref:`video output overlay <osd>` devices) read the alpha
+component from memory. When the device processes the alpha channel the
+alpha component must be filled with meaningful values by applications.
+Otherwise a corresponding format without an alpha component (XRGB or
+XBGR) must be used instead of an alpha format.
+
+The XRGB and XBGR formats contain undefined bits (-). Applications,
+devices and drivers must ignore those bits, for both
+:ref:`capture` and :ref:`output` devices.

> +The raw Bayer formats are used by image sensors before much if any processing is
> +performed on the image. The formats contain green, red and blue components, with
> +alternating lines of red and green, and blue and green pixels in different
> +orders. See also `the Wikipedia article on Bayer filter
