Hi all,
I have a setup on my TQMa6x (imx6q-mba6a.dts) with a tc358743 attached to the
MIPI CSI input.
I noticed that since commit 1f391df44607 ("media: v4l2-async: Use endpoints in
__v4l2_async_nf_add_fwnode_remote()") the async subdevice probing does not
work anymore. If I revert that, it is working again, even on next-20230425.
$ cat /sys/kernel/debug/v4l2-async/pending_async_subdevices
imx-media:
ipu2_csi1:
ipu2_csi0:
[fwnode] dev=21dc000.mipi, node=/soc/bus@2100000/mipi@21dc000/port@3/endpoint
ipu1_csi1:
[fwnode] dev=21dc000.mipi, node=/soc/bus@2100000/mipi@21dc000/port@2/endpoint
ipu1_csi0:
imx6-mipi-csi2:
ipu2_csi1_mux:
ipu1_csi0_mux:
[fwnode] dev=21dc000.mipi, node=/soc/bus@2100000/mipi@21dc000/port@1/endpoint
With revert:
$ cat /sys/kernel/debug/v4l2-async/pending_async_subdevices
imx-media:
ipu2_csi1:
ipu2_csi0:
ipu1_csi1:
ipu1_csi0:
imx6-mipi-csi2:
ipu2_csi1_mux:
ipu1_csi0_mux:
I also see these messages:
> video-mux 20e0000.iomuxc-gpr:ipu2_csi1_mux: Consider updating driver video-
mux to match on endpoints
> imx6-mipi-csi2 21dc000.mipi: Consider updating driver imx6-mipi-csi2 to
match on endpoints
> tc358743 0-000f: Consider updating driver tc358743 to match on endpoints
> video-mux 20e0000.iomuxc-gpr:ipu1_csi0_mux: Consider updating driver video-
mux to match on endpoints
But I'm unsure if this is related. As far as I can see match_fwnode_one does
match some nodes, but I do not know if they are the correct ones.
Anyone has an idea what's wrong here?
Best regards,
Alexander
