+Freescale Pixel Pipeline
+========================
+
+The Pixel Pipeline (PXP) is a memory-to-memory graphics processing engine
+that supports scaling, colorspace conversion, alpha blending, rotation, and
+pixel conversion via lookup table. Different versions are present on various
+i.MX SoCs from i.MX23 to i.MX7.
+
+Required properties:
+- compatible: should be "fsl,<soc>-pxp", where SoC can be one of imx23, imx28,
+ imx6dl, imx6sl, imx6ul, imx6sx, imx6ull, or imx7d.
+- reg: the register base and size for the device registers
+- interrupts: the PXP interrupt, two interrupts for imx6ull and imx7d.
+- clock-names: should be "axi"
+- clocks: the PXP AXI clock
+
+Example:
+
+pxp@21cc000 {
+ compatible = "fsl,imx6ull-pxp";
+ reg = <0x021cc000 0x4000>;
+ interrupts = <GIC_SPI 8 IRQ_TYPE_LEVEL_HIGH>,
+ <GIC_SPI 18 IRQ_TYPE_LEVEL_HIGH>;
+ clock-names = "axi";
+ clocks = <&clks IMX6UL_CLK_PXP>;

+Intel D4xx UVC Cameras Metadata
+
+
+Description
+===========
+
+Intel D4xx (D435 and other) cameras include per-frame metadata in their UVC
+payload headers, following the Microsoft(R) UVC extension proposal [1_]. That
+means, that the private D4XX metadata, following the standard UVC header, is
+organised in blocks. D4XX cameras implement several standard block types,
+proposed by Microsoft, and several proprietary ones. Supported standard metadata
+types are MetadataId_CaptureStats (ID 3), MetadataId_CameraExtrinsics (ID 4),
+and MetadataId_CameraIntrinsics (ID 5). For their description see [1_]. This
+document describes proprietary metadata types, used by D4xx cameras.
+
+V4L2_META_FMT_D4XX buffers follow the metadata buffer layout of
+V4L2_META_FMT_UVC with the only difference, that it also includes proprietary
+payload header data. D4xx cameras use bulk transfers and only send one payload
+per frame, therefore their headers cannot be larger than 255 bytes.
+
+Below are proprietary Microsoft style metadata types, used by D4xx cameras,
+where all fields are in little endian order:
