Merge tag 'media/v3.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media
Pull media updates from Mauro Carvalho Chehab: - Two new dvb frontend drivers: mn88472 and mn88473 - A new driver for some PCIe DVBSky cards - A new remote controller driver: meson-ir - One LIRC staging driver got rewritten and promoted to mainstream: igorplugusb - A new tuner driver (m88rs6000t) - The old omap2 media driver got removed from staging. This driver uses an old DMA API and it is likely broken on recent kernels. Nobody cared enough to fix it - Media bus format moved to a separate header, as DRM will also use the definitions there - mem2mem_testdev were renamed to vim2m, in order to use the same naming convention taken by the other virtual test driver (vivid) - Added a new driver for coda SoC (coda-jpeg) - The cx88 driver got converted to use videobuf2 core - Make DMABUF export buffer to work with DMA Scatter/Gather and Vmalloc cores - Lots of other fixes, improvements and cleanups on the drivers. * tag 'media/v3.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media: (384 commits) [media] mn88473: One function call less in mn88473_init() after error [media] mn88473: Remove uneeded check before release_firmware() [media] lirc_zilog: Deletion of unnecessary checks before vfree() [media] MAINTAINERS: Add myself as img-ir maintainer [media] img-ir: Don't set driver's module owner [media] img-ir: Depend on METAG or MIPS or COMPILE_TEST [media] img-ir/hw: Drop [un]register_decoder declarations [media] img-ir/hw: Fix potential deadlock stopping timer [media] img-ir/hw: Always read data to clear buffer [media] redrat3: ensure dma is setup properly [media] ddbridge: remove unneeded check before dvb_unregister_device() [media] si2157: One function call less in si2157_init() after error [media] tuners: remove uneeded checks before release_firmware() [media] arm: omap2: rx51-peripherals: fix build warning [media] stv090x: add an extra protetion against buffer overflow [media] stv090x: Remove an unreachable code [media] stv090x: Some whitespace cleanups [media] em28xx: checkpatch cleanup: whitespaces/new lines cleanups [media] si2168: add support for firmware files in new format [media] si2168: debug printout for firmware version ...

+ <para>Color exists only in the eye and brain and is the result of how strongly
+color receptors are stimulated. This is based on the Spectral
+Power Distribution (SPD) which is a graph showing the intensity (radiant power)
+of the light at wavelengths covering the visible spectrum as it enters the eye.
+The science of colorimetry is about the relationship between the SPD and color as
+perceived by the human brain.</para>
+
+ <para>Since the human eye has only three color receptors it is perfectly
+possible that different SPDs will result in the same stimulation of those receptors
+and are perceived as the same color, even though the SPD of the light is
+different.</para>
+
+ <para>In the 1920s experiments were devised to determine the relationship
+between SPDs and the perceived color and that resulted in the CIE 1931 standard
+that defines spectral weighting functions that model the perception of color.
+Specifically that standard defines functions that can take an SPD and calculate
+the stimulus for each color receptor. After some further mathematical transforms
+these stimuli are known as the <emphasis>CIE XYZ tristimulus</emphasis> values
+and these X, Y and Z values describe a color as perceived by a human unambiguously.
+These X, Y and Z values are all in the range [0&hellip;1].</para>
+
+ <para>The Y value in the CIE XYZ colorspace corresponds to luminance. Often
+the CIE XYZ colorspace is transformed to the normalized CIE xyY colorspace:</para>
+
+ <para>x = X / (X + Y + Z)</para>
+ <para>y = Y / (X + Y + Z)</para>
+
+ <para>The x and y values are the chromaticity coordinates and can be used to
+define a color without the luminance component Y. It is very confusing to
+have such similar names for these colorspaces. Just be aware that if colors
+are specified with lower case 'x' and 'y', then the CIE xyY colorspace is
+used. Upper case 'X' and 'Y' refer to the CIE XYZ colorspace. Also, y has nothing
+to do with luminance. Together x and y specify a color, and Y the luminance.
+That is really all you need to remember from a practical point of view. At
+the end of this section you will find reading resources that go into much more
+detail if you are interested.
+</para>
+
+ <para>A monitor or TV will reproduce colors by emitting light at three
+different wavelengths, the combination of which will stimulate the color receptors
+in the eye and thus cause the perception of color. Historically these wavelengths
+were defined by the red, green and blue phosphors used in the displays. These
+<emphasis>color primaries</emphasis> are part of what defines a colorspace.</para>
+
+ <para>Different display devices will have different primaries and some
+primaries are more suitable for some display technologies than others. This has
+resulted in a variety of colorspaces that are used for different display
+technologies or uses. To define a colorspace you need to define the three
+color primaries (these are typically defined as x,&nbsp;y chromaticity coordinates
+from the CIE xyY colorspace) but also the white reference: that is the color obtained
+when all three primaries are at maximum power. This determines the relative power
+or energy of the primaries. This is usually chosen to be close to daylight which has
+been defined as the CIE D65 Illuminant.</para>
+
+ <para>To recapitulate: the CIE XYZ colorspace uniquely identifies colors.
+Other colorspaces are defined by three chromaticity coordinates defined in the
+CIE xyY colorspace. Based on those a 3x3 matrix can be constructed that
+transforms CIE XYZ colors to colors in the new colorspace.
+</para>
+
+ <para>Both the CIE XYZ and the RGB colorspace that are derived from the
+specific chromaticity primaries are linear colorspaces. But neither the eye,
+nor display technology is linear. Doubling the values of all components in
+the linear colorspace will not be perceived as twice the intensity of the color.
+So each colorspace also defines a transfer function that takes a linear color
+component value and transforms it to the non-linear component value, which is a
+closer match to the non-linear performance of both the eye and displays. Linear
+component values are denoted RGB, non-linear are denoted as R'G'B'. In general
+colors used in graphics are all R'G'B', except in openGL which uses linear RGB.
+Special care should be taken when dealing with openGL to provide linear RGB colors
+or to use the built-in openGL support to apply the inverse transfer function.</para>
+
+ <para>The final piece that defines a colorspace is a function that
+transforms non-linear R'G'B' to non-linear Y'CbCr. This function is determined
+by the so-called luma coefficients. There may be multiple possible Y'CbCr
+encodings allowed for the same colorspace. Many encodings of color
+prefer to use luma (Y') and chroma (CbCr) instead of R'G'B'. Since the human
+eye is more sensitive to differences in luminance than in color this encoding
+allows one to reduce the amount of color information compared to the luma
+data. Note that the luma (Y') is unrelated to the Y in the CIE XYZ colorspace.
+Also note that Y'CbCr is often called YCbCr or YUV even though these are
+strictly speaking wrong.</para>
+
+ <para>Sometimes people confuse Y'CbCr as being a colorspace. This is not
+correct, it is just an encoding of an R'G'B' color into luma and chroma
+values. The underlying colorspace that is associated with the R'G'B' color
+is also associated with the Y'CbCr color.</para>
+
+ <para>The final step is how the RGB, R'G'B' or Y'CbCr values are
+quantized. The CIE XYZ colorspace where X, Y and Z are in the range
+[0&hellip;1] describes all colors that humans can perceive, but the transform to
+another colorspace will produce colors that are outside the [0&hellip;1] range.
+Once clamped to the [0&hellip;1] range those colors can no longer be reproduced
+in that colorspace. This clamping is what reduces the extent or gamut of the
+colorspace. How the range of [0&hellip;1] is translated to integer values in the
+range of [0&hellip;255] (or higher, depending on the color depth) is called the
+quantization. This is <emphasis>not</emphasis> part of the colorspace
+definition. In practice RGB or R'G'B' values are full range, i.e. they
+use the full [0&hellip;255] range. Y'CbCr values on the other hand are limited
+range with Y' using [16&hellip;235] and Cb and Cr using [16&hellip;240].</para>
+
+ <para>Unfortunately, in some cases limited range RGB is also used
+where the components use the range [16&hellip;235]. And full range Y'CbCr also exists
+using the [0&hellip;255] range.</para>
+
+ <para>In order to correctly interpret a color you need to know the
+quantization range, whether it is R'G'B' or Y'CbCr, the used Y'CbCr encoding
+and the colorspace.
+From that information you can calculate the corresponding CIE XYZ color
+and map that again to whatever colorspace your display device uses.</para>
+
+ <para>The colorspace definition itself consists of the three
+chromaticity primaries, the white reference chromaticity, a transfer
+function and the luma coefficients needed to transform R'G'B' to Y'CbCr. While
+some colorspace standards correctly define all four, quite often the colorspace
+standard only defines some, and you have to rely on other standards for
+the missing pieces. The fact that colorspaces are often a mix of different
+standards also led to very confusing naming conventions where the name of
+a standard was used to name a colorspace when in fact that standard was
+part of various other colorspaces as well.</para>
+
+ <para>If you want to read more about colors and colorspaces, then the
+following resources are useful: <xref linkend="poynton" /> is a good practical
+book for video engineers, <xref linkend="colimg" /> has a much broader scope and
+describes many more aspects of color (physics, chemistry, biology, etc.).
+The <ulink url="http://www.brucelindbloom.com">http://www.brucelindbloom.com</ulink>
+website is an excellent resource, especially with respect to the mathematics behind
+colorspace conversions. The wikipedia <ulink url="http://en.wikipedia.org/wiki/CIE_1931_color_space#CIE_xy_chromaticity_diagram_and_the_CIE_xyY_color_space">CIE 1931 colorspace</ulink> article
+is also very useful.</para>

+ <title>Defining Colorspaces in V4L2</title>
+ <para>In V4L2 colorspaces are defined by three values. The first is the colorspace
+identifier (&v4l2-colorspace;) which defines the chromaticities, the transfer
+function, the default Y'CbCr encoding and the default quantization method. The second
+is the Y'CbCr encoding identifier (&v4l2-ycbcr-encoding;) to specify non-standard
+Y'CbCr encodings and the third is the quantization identifier (&v4l2-quantization;)
+to specify non-standard quantization methods. Most of the time only the colorspace
+field of &v4l2-pix-format; or &v4l2-pix-format-mplane; needs to be filled in. Note
+that the default R'G'B' quantization is always full range for all colorspaces,
+so this won't be mentioned explicitly for each colorspace description.</para>
