Hi Sascha,
Something with port and endpoint gives notifications.
Somehow with the conversion of rockchip,dw-hdmi.txt to YAML not all SoC
options were checked/covered (see rk3328 and rk3568).
Allow multiple vop:
port or
port@0
1x vop -> endpoint
2x vop -> endpoint@0
-> endpoint@1
Also allow for connector:
(not all existing DT have this yet)
port@1
-> endpoint
See also at graph.yaml
