ASRC in IMX8M Mini SoC

We are working with IMX8M Mini EVK. I am having a doubt regarding the ASRC.

Is ASRC HW block is present in the IMX8M Mini?


1. From the feature comparison section :

i.MX8M Nano has ASRC and i.MX8 Mini has no ASRC


2. But from the i.MX 8M Mini Applications Processor Reference Manual, SPDIF Rx Clock is fed to ASRC.

Please find the attachment.


3. In the kernel code: sound/soc/fsl/fsl-asrc.c is built into the kernel.


I could not understand this conflict details. Please clarify me whether ASRC is included in IMX8M Mini as internal hw.


Thank you, Sreedhar
