Are Xilinx I2S IP drivers compatible with Linux ASoC simple-card driver?

Hi.
I built a block design with Xilinx I2S IP Cores. The Design includes Xilinx I2S Receiver and I2S Transimiter IP core. It also includes the Xilinx Audio Formatter IP core. All of them have Linux mainline drivers and they are automatically set up by petalinux.

I want to create a sound card using the simple-card.c machine driver. Somehow it doesn't work. While booting I get this message:
asoc-simple-card sound0: parse error -22

Is the Xilinx Audio Formatter IP core incomaptible with the ASoC simple-card driver? Or are they compatible? What do I have to do in order to make it work?

I few posts about this topic on the net but I couldn't find a solution for this issue.
The user bhig of this forum thinks that the Audio Formatter driver is incompatible with the Xilinx Audio Formatter driver:
