Hi Steve,

I have just tested the imx-media-staging-md-wip branch on a Nitrogen6X
with a tc358743 (BD_HDMI_MIPI HDMI to MIPI CSI-2 receiver board). Some
observations:

# Link pipeline
media-ctl -l "'tc358743 1-000f':0->'imx6-mipi-csi2':0[1]"
media-ctl -l "'imx6-mipi-csi2':1->'ipu1_csi0_mux':0[1]"
media-ctl -l "'ipu1_csi0_mux':2->'ipu1_csi0':0[1]"
media-ctl -l "'ipu1_csi0':2->'ipu1_csi0 capture':0[1]"

# Provide an EDID to the HDMI source
v4l2-ctl -d /dev/v4l-subdev2 --set-edid=file=edid-1080p.hex
# At this point the HDMI source is enabled and sends a 1080p60 signal
# Configure detected DV timings
media-ctl --set-dv "'tc358743 1-000f':0"

# Set pad formats
media-ctl --set-v4l2 "'tc358743 1-000f':0[fmt:UYVY/1920x1080]"
media-ctl --set-v4l2 "'imx6-mipi-csi2':1[fmt:UYVY2X8/1920x1080]"
media-ctl --set-v4l2 "'ipu1_csi0_mux':2[fmt:UYVY2X8/1920x1080]"

I noticed this seems to get ignored. The format is incorrectly set to
UYVY even though I request UYVY2X8 (see CSI2IPU chapter, Figure 19-10.
YUV422-8 data reception in the reference manual), but it seems to work
anyway.

regards
Philipp
