Subject: [PATCH v2 02/19] ARM: dts: imx6qdl: Add mipi_ipu1/2 multiplexers, mipi_csi, and their connections

From: Philipp Zabel <p.zabel@...gutronix.de>

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.

Signed-off-by: Philipp Zabel <p.zabel@...gutronix.de>

- Removed some dangling/unused endpoints (ipu2_csi0_from_csi2ipu)
- Renamed the mipi virtual channel endpoint labels, from "mipi_csiX_..."
  to "mipi_vcX...".
- Added input endpoints to the video muxes for the connections from parallel
  sensors.
- Added input endpoints to the mipi_csi for the connections from mipi csi-2
  sensors.
- The video multiplexer node has compatible string "imx-video-mux" instead
  of "video-multiplexer".
- The video multiplexer node indicates GPR register via reg propert only,
  (register offset and bitmask), instead of specifying with "bit-mask" and
  "bit-shift" properties.
