Merge branch 'v4l_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media

Browse source 
Pull media updates from Mauro Carvalho Chehab:
 "This series contains:
   - Exynos s5p-mfc driver got support for VP8 encoder
   - Some SoC drivers gained support for asynchronous registration
     (needed for DT)
   - The RC subsystem gained support for RC activity LED;
   - New drivers added: a video decoder(adv7842), a video encoder
     (adv7511), a new GSPCA driver (stk1135) and support for Renesas
     R-Car (vsp1)
   - the first SDR kernel driver: mirics msi3101.  Due to some troubles
     with the driver, and because the API is still under discussion, it
     will be merged at staging for 3.12.  Need to rework on it
   - usual new boards additions, fixes, cleanups and driver
     improvements"

<title>Description</title>
<para>This is a multi-planar, two-plane version of the YUV 4:2:0 format.
The three components are separated into two sub-images or planes.
<constant>V4L2_PIX_FMT_NV16M</constant> differs from <constant>V4L2_PIX_FMT_NV16
</constant> in that the two planes are non-contiguous in memory, i.e. the chroma
plane does not necessarily immediately follows the luma plane.
The luminance data occupies the first plane. The Y plane has one byte per pixel.
In the second plane there is chrominance data with alternating chroma samples.
The CbCr plane is the same width and height, in bytes, as the Y plane.
Each CbCr pair belongs to four pixels. For example,
Cb<subscript>0</subscript>/Cr<subscript>0</subscript> belongs to
Y'<subscript>00</subscript>, Y'<subscript>01</subscript>,
Y'<subscript>10</subscript>, Y'<subscript>11</subscript>.
<constant>V4L2_PIX_FMT_NV61M</constant> is the same as <constant>V4L2_PIX_FMT_NV16M</constant>
except the Cb and Cr bytes are swapped, the CrCb plane starts with a Cr byte.</para>
<para><constant>V4L2_PIX_FMT_NV16M</constant> and
<constant>V4L2_PIX_FMT_NV61M</constant> are intended to be used only in drivers
and applications that support the multi-planar API, described in

* Analog Devices adv7343 video encoder
The ADV7343 are high speed, digital-to-analog video encoders in a 64-lead LQFP
package. Six high speed, 3.3 V, 11-bit video DACs provide support for composite
(CVBS), S-Video (Y-C), and component (YPrPb/RGB) analog outputs in standard
definition (SD), enhanced definition (ED), or high definition (HD) video
formats.
Required Properties :
- compatible: Must be "adi,adv7343"
Optional Properties :
- adi,power-mode-sleep-mode: on enable the current consumption is reduced to
micro ampere level. All DACs and the internal PLL
circuit are disabled.
- adi,power-mode-pll-ctrl: PLL and oversampling control. This control allows
internal PLL 1 circuit to be powered down and the
oversampling to be switched off.
- ad,adv7343-power-mode-dac: array configuring the power on/off DAC's 1..6,
0 = OFF and 1 = ON, Default value when this
property is not specified is <0 0 0 0 0 0>.
- ad,adv7343-sd-config-dac-out: array configure SD DAC Output's 1 and 2, 0 = OFF
and 1 = ON, Default value when this property is
not specified is <0 0>.
Example:
i2c0@1c22000 {
...
...
adv7343@2a {
compatible = "adi,adv7343";
reg = <0x2a>;
port {
adv7343_1: endpoint {
adi,power-mode-sleep-mode;
adi,power-mode-pll-ctrl;
/* Use DAC1..3, DAC6 */
adi,dac-enable = <1 1 1 0 0 1>;
/* Use SD DAC output 1 */
adi,sd-dac-enable = <1 0>;

* Texas Instruments TV7002 video decoder
The TVP7002 device supports digitizing of video and graphics signal in RGB and
YPbPr color space.
Required Properties :
- compatible : Must be "ti,tvp7002"
Optional Properties:
- hsync-active: HSYNC Polarity configuration for the bus. Default value when
this property is not specified is <0>.
- vsync-active: VSYNC Polarity configuration for the bus. Default value when
this property is not specified is <0>.
- pclk-sample: Clock polarity of the bus. Default value when this property is
not specified is <0>.
- sync-on-green-active: Active state of Sync-on-green signal property of the
endpoint.
0 = Normal Operation (Active Low, Default)
1 = Inverted operation
- field-even-active: Active-high Field ID output polarity control of the bus.
Under normal operation, the field ID output is set to logic 1 for an odd field
(field 1) and set to logic 0 for an even field (field 0).
0 = Normal Operation (Active Low, Default)
1 = FID output polarity inverted
For further reading of port node refer Documentation/devicetree/bindings/media/
video-interfaces.txt.
Example:
i2c0@1c22000 {
...
...
tvp7002@5c {
