This patch adds the device tree graph connecting the input multiplexers to the IPU CSIs and the MIPI-CSI2 gasket on i.MX6. The MIPI_IPU multiplexers are added as children of the iomuxc-gpr syscon device node. On i.MX6Q/D two two-input multiplexers in front of IPU1 CSI0 and IPU2 CSI1 allow to select between CSI0/1 parallel input pads and the MIPI CSI-2 virtual channels 0/3. On i.MX6DL/S two five-input multiplexers in front of IPU1 CSI0 and IPU1 CSI1 allow to select between CSI0/1 parallel input pads and any of the four MIPI CSI-2 virtual channels. Changes from Steve Longerbeam: - Removed some dangling/unused endpoints (ipu2_csi0_from_csi2ipu) - Renamed the mipi virtual channel endpoint labels, from "mipi_csiX_..." to "mipi_vcX...". - Added input endpoint anchors to the video muxes for the connections from parallel sensors.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
