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 sabrea Signed-off-by: Fabio Estevam <festevam@gmail.com> --- Changes since v2: - Fix I2C and CSI mux numbering (Steve) - Passed the v4l2-ctl configuration (Steve) Documentation/media/v4l-drivers/imx.rst | 58 +++++++++++++++++++++++++ 1 file changed, 58 insertions(+)
