Query on audio-graph-card DT binding

[Sameer Pujar <spujar@nvidia.com>]

Hi Morimoto-san,

This question is regarding audio-graph-card.c driver related DT binding.

I am looking to enable following DAI link connection in device tree for 
Tegra audio:

               /-----> codec1 endpoint
              /
CPU endpoint \
               \-----> codec2 endpoint


I see that, "remote-endpoint" property can only specify single phandle 
object for connection to a remote endpoint. In other words, the link can 
be one-to-one. For illustration, please see below example. However I see 
it leads to a build error if phandle-array is provided for 
"remote-endpoint" property.

  cpu_port {
      cpu_ep: endpoint {
          remote-endpoint = <&codec1_ep>, <&codec2_ep>;
      };
  };

  codec1 {
      codec1_ep: endpoint {
          remote-endpoint = <&cpu_ep>;
      };
  };

  codec2 {
      codec2_ep: endpoint {
          remote-endpoint = <&cpu_ep>;
      };
  };

Is there a possibility to re-use the same CPU endpoint for connecting to 
multiple codec endpoints like shown in above example?


Thanks,
Sameer.
