Merge tag 'media/v4.1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media

Pull media updates from Mauro Carvalho Chehab:

 - a new frontend driver for new ATSC devices: lgdt3306a

 - a new sensor driver: ov2659

 - a new platform driver: xilinx

 - the m88ts2022 tuner driver was merged at ts2020 driver

 - the media controller gained experimental support for DVB and hybrid
   devices

 - lots of random cleanups, fixes and improvements on media drivers

+
+The Omnivision OV2659 is a 1/5-inch SOC camera, with an active array size of
+1632H x 1212V. It is programmable through a SCCB. The OV2659 sensor supports
+multiple resolutions output, such as UXGA, SVGA, 720p. It also can support
+YUV422, RGB565/555 or raw RGB output formats.
+
+Required Properties:
+- compatible: Must be "ovti,ov2659"
+- reg: I2C slave address
+- clocks: reference to the xvclk input clock.
+- clock-names: should be "xvclk".
+- link-frequencies: target pixel clock frequency.
+
+For further reading on port node refer to
+Documentation/devicetree/bindings/media/video-interfaces.txt.

+DT bindings for Xilinx video IP cores
+-------------------------------------
+
+Xilinx video IP cores process video streams by acting as video sinks and/or
+sources. They are connected by links through their input and output ports,
+creating a video pipeline.
+
+Each video IP core is represented by an AMBA bus child node in the device
+tree using bindings documented in this directory. Connections between the IP
+cores are represented as defined in ../video-interfaces.txt.
+
+The whole  pipeline is represented by an AMBA bus child node in the device
+tree using bindings documented in ./xlnx,video.txt.
+
+Common properties
+-----------------
+
+The following properties are common to all Xilinx video IP cores.
+
+- xlnx,video-format: This property represents a video format transmitted on an
+  AXI bus between video IP cores, using its VF code as defined in "AXI4-Stream
+  Video IP and System Design Guide" [UG934]. How the format relates to the IP
+  core is decribed in the IP core bindings documentation.
+
+- xlnx,video-width: This property qualifies the video format with the sample
+  width expressed as a number of bits per pixel component. All components must
+  use the same width.
+
+- xlnx,cfa-pattern: When the video format is set to Mono/Sensor, this property
+  describes the sensor's color filter array pattern. Supported values are
+  "bggr", "gbrg", "grbg", "rggb" and "mono". If not specified, the pattern
+  defaults to "mono".

+
+  - reg: Physical base address and length of the registers set for the device.

+Xilinx Video IP Pipeline (VIPP)
+-------------------------------
+
+General concept
+---------------
+
+Xilinx video IP pipeline processes video streams through one or more Xilinx
+video IP cores. Each video IP core is represented as documented in video.txt
+and IP core specific documentation, xlnx,v-*.txt, in this directory. The DT
+node of the VIPP represents as a top level node of the pipeline and defines
+mappings between DMAs and the video IP cores.
+
+Required properties:
+
+- compatible: Must be "xlnx,video".
+
+- dmas, dma-names: List of one DMA specifier and identifier string (as defined
+  in Documentation/devicetree/bindings/dma/dma.txt) per port. Each port
+  requires a DMA channel with the identifier string set to "port" followed by
+  the port index.
+
+- ports: Video port, using the DT bindings defined in ../video-interfaces.txt.
+
+Required port properties:
+
+- direction: should be either "input" or "output" depending on the direction
+  of stream.
+
+Example:
+
+	video_cap {
+		compatible = "xlnx,video";
