Hi list,
(long time no see!)
I switched from a Freescale kernel 5.4 to a vanilla 5.10 on IMX6Solo
board. The device is using a ADV7280 as analog-video-ADC.
I tried to apply the good options to my kernel-config, but I'm unable
to get the media-controller device appear. I see
[ 757.594463] irq: type mismatch, failed to map hwirq-21 for gpio@20a8000!
[ 757.655328] adv7180 2-0021: chip found @ 0x21 (21a8000.i2c)
that the adv7280 is found and attached, as well as the ipu and it's
video-devices.
[ 11.069123] videodev: Linux video capture interface: v2.00
[ 12.553347] ipu1_csi0: Registered ipu1_csi0 capture as /dev/video0
[ 12.681897] ipu1_ic_prpenc: Registered ipu1_ic_prpenc capture as /dev/video1
[ 12.785205] ipu1_ic_prpvf: Registered ipu1_ic_prpvf capture as /dev/video2
[ 12.914702] ipu1_csi1: Registered ipu1_csi1 capture as /dev/video3
I'm using the same device-tree as I used with fscl-5.4.
Before writing an even longer email pasting everything I did I'd like
to know which information is actually useful to debug this?
I'm hoping there is something obvious which I missed?
I'm wondering whether I shoud v4l-subdev to be created, which I don't
in dmesg.
Thanks in advance for any help,
--
Patrick.

I was missing CONFIG_MUX_MMIO. Strange that it's not activated by
default.
Should it?
