I'm using a i.MX 8QuadXPlus on a custom board. I'm having problems using a custom
audio card driver, which uses sai2 peripheral (rx only).
The error I'm getting is:
fsl-sai 59060000.sai: ASoC: can't open platform 59060000.sai: -6
I've found this error (ENXIO) to be generated from
function called in imx-pcm-dma-v2.c while opening pcm stream.
Since I think it's a dma related problem, I've looked into fsl-imx8dx.dtsi and it seems that edma0 definition is missing
sai2 and sai3 configuration, so I've added it on my own, but I'm getting the same error again and again.
I'm using linux-imx 4.9.88-r0 from codeaurora.org.
