From 2539f517acbdc8471f0aebdffe894eb571103368 Mon Sep 17 00:00:00 2001 From: Philipp Zabel Date: Mon, 12 Jun 2017 11:23:56 -0700 Subject: [PATCH] ARM: dts: imx6qdl: Add video multiplexers, mipi_csi, and their connections 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.
