For me this fails when I try to enable both video muxes (mx6dl, though
mx6q should be the same).
I get a sysfs duplicate name failure for 34.videomux. I realise
passing the GPR13 register offset and a bitfield mask as a tuple in
the reg value of the of_node is handy, but how should we account for
multiple devices with the same name and address?
A quick and dirty hack would be to have of_get_reg_field do something
like
field->reg = reg_bit_mask[0] & 0xff;
and then use values in the DT that differ in the bits masked off, but
there must be a nicer way.
Trace below, fyi. This is from the v2 patches posted here, not your
v2.1 tree.
Hi Ian,
Thanks for catching this. I found a simple and clean solution to this
problem: just rename the video-mux node from "videomux" to
"ipu[12]_csi[01]_mux". It makes the subdev names more descriptive
anyway. I've applied that change to my mx6-media-staging-v2.1
branch.
