Hmm... it seems strange...
I guess you are using "ti,omap4-mcbsp" driver (= linux/sound/soc/omap/omap-mcbsp.c)
Is this correct ?
If so, your driver is registering component as
ret = devm_snd_soc_register_component(&pdev->dev,
&omap_mcbsp_component,
&omap_mcbsp_dai, 1);
Your driver has only 1 DAI.

And here, you have 1 port, 2 endpoint.
Then, asoc_simple_card_get_dai_id() should return 1.
And, your [2/2] patch,
I guess you are misunderstanding about "port" vs "endpoint",
or omap-mcbsp driver side need to update ?
