Hi Fabio,
if this ( https://patchwork.kernel.org/patch/9952385/ ) is the patch, then it seems to be
specific to the Freescale I2S controller. We use the SGTL5000 together with a Rockchip CPU.
I think I see a way to fix this without adding a DTS property, I’ll send out a patch later this afternoon.
Best regards,
