I just booted the imx6q SabreAuto with 5.4.0-rc1 (and media-tree HEAD
3ff3a712a9ea), I am getting:
arm:~ % uname -r
5.4.0-rc1-13672-g3ff3a712a9ea
arm:~ % dmesg | grep 'ipu[12]_csi[01]_mux'
[ 13.042519] imx-media: ipu1_csi0_mux:2 -> ipu1_csi0:0
[ 13.042590] imx-media: ipu2_csi1_mux:2 -> ipu2_csi1:0
[ 13.042656] imx-media: adv7180 3-0021:0 -> ipu1_csi0_mux:1
arm:~ % dmesg | grep adv7180
[ 12.905157] adv7180 3-0021: chip found @ 0x21 (i2c-2-mux (chan_id 1))
[ 13.042656] imx-media: adv7180 3-0021:0 -> ipu1_csi0_mux:1
So the adv7180 i2c-bus and pad numbers have not changed. The adv7180 is
still on bus 3, and the output pad from the IPU-CSI video muxes are
still pad 2. The video muxes have no such pad 5 in fact. I'd be curious
in learning how you came about that pad number.

Thanks for catching that, it was left over from a pipeline configuration
script of mine.
