I've taken a shot today trying to convert over to the audio-graph-card method (which isn't yet upstream, but in -next), but I've been running into some quirks.
Part of the issue is the adv7533 bridge already has a endpoint port entry for the dsi output. So when I add the codec_endpoint port, it wants the two port entries to be enumerated, so I get something like:
port@0 { adv7533_in: endpoint { remote-endpoint = <&dsi_out0>; }; }; port@1 { codec_endpoint: endpoint { remote-endpoint = <&i2s0_cpu_endpoint>; }; };
But this causes it to try to link to hdmi-hifi.1 (which doesn't exist) instead of hdmi-hifi.0.
If I instead swap the entries, so the codec_endpoint is first on port 0, then the the audio link is properly setup, but the dsi initialization falls over.
Any suggestions here?
thanks -john
