media: imx.rst: Provide instructions for the i.MX6DL sabreauto
The i.MX6DL sabreauto has different numbering on the I2C bus and I2C muxes compared to the i.MX6Q as shown in the kernel log below: [ 5.159423] imx-media: ipu1_csi0_mux:5 -> ipu1_csi0:0 [ 5.164618] imx-media: ipu1_csi1_mux:5 -> ipu1_csi1:0 [ 5.169953] imx-media: adv7180 4-0021:0 -> ipu1_csi0_mux:4 To avoid confusion, add an entry that shows how to setup the links and configure the pads that are specific to the i.MX6DL sabreauto.

i.MX6DL SabreAuto with ADV7180 decoder
|
||||
--------------------------------------
|
||||
|
||||
On the i.MX6DL SabreAuto, an on-board ADV7180 SD decoder is connected to the
|
||||
parallel bus input on the internal video mux to IPU1 CSI0.
|
||||
|
||||
The following example configures a pipeline to capture from the ADV7180
|
||||
video decoder, assuming NTSC 720x480 input signals, using simple
|
||||
interweave (unconverted and without motion compensation). The adv7180
|
||||
must output sequential or alternating fields (field type 'seq-bt' for
|
||||
NTSC, or 'alternate'):
|
||||
|
||||
.. code-block:: none
|
||||
|
||||
# Setup links
|
||||
media-ctl -l "'adv7180 4-0021':0 -> 'ipu1_csi0_mux':4[1]"
|
||||
media-ctl -l "'ipu1_csi0_mux':5 -> 'ipu1_csi0':0[1]"
|
||||
media-ctl -l "'ipu1_csi0':2 -> 'ipu1_csi0 capture':0[1]"
|
||||
# Configure pads
|
||||
media-ctl -V "'adv7180 4-0021':0 [fmt:UYVY2X8/720x480 field:seq-bt]"
|
||||
media-ctl -V "'ipu1_csi0_mux':5 [fmt:UYVY2X8/720x480]"
|
||||
media-ctl -V "'ipu1_csi0':2 [fmt:AYUV32/720x480]"
|
||||
# Configure "ipu1_csi0 capture" interface (assumed at /dev/video0)
|
||||
v4l2-ctl -d0 --set-fmt-video=field=interlaced_bt
|
||||
|
||||
Streaming can then begin on /dev/video0. The v4l2-ctl tool can also be
|
||||
used to select any supported YUV pixelformat on /dev/video0.
|
||||
|
||||
This example configures a pipeline to capture from the ADV7180
|
||||
video decoder, assuming PAL 720x576 input signals, with Motion
|
||||
Compensated de-interlacing. The adv7180 must output sequential or
|
||||
alternating fields (field type 'seq-tb' for PAL, or 'alternate').

|
||||
v4l2-ctl -d2 --set-fmt-video=field=none
|
||||
|
||||
Streaming can then begin on /dev/video2. The v4l2-ctl tool can also be
|
||||
used to select any supported YUV pixelformat on /dev/video2.
