In my machine, there is only one audio device and the CODECs don't need any format, sysclk or TDM slot.
But, as Jyri asked it too, I will add these properties.

As Jyri said: why not two simple-cards?

The audio (platform) device of my machine has two outputs (I2S and S/PDIF = CPU DAIs) which are connected to different CODECs (HDMI transmitter and S/PDIF connector).
There must be two different HDMI CODECs because the format and rate constraints of the wires (I2S and S/PDIF) are different.
There is only one playback stream.
