No underscores in node names. Use consistent naming - do you see here
any nodes named "mclk"?

Anyway this is some fake clock. Real clock should come out from wm8960.

1. Why card0?
2. Where is this node located? In MMIO bus? Run some basic checks on
your DTS before submitting upstream.
dtbs_check
dtbs W=1

3. Why this is even in the DTSI? This really looks wrong.

Hi Conor,

The TDM need work together with external codec WM8960 by plugging the raspberry pie
 audio board into the 40-pin, which is found in sheet 21 of the schematic. Because the
 40-pin of VisionFive2 is fully compatible with the pins of Raspberry pie audio board. 

For more information of the audio board, you can take a look at the following webpage:
https://wiki.seeedstudio.com/ReSpeaker_2_Mics_Pi_HAT/

The schematic of audio board:
https://files.seeedstudio.com/wiki/MIC_HATv1.0_for_raspberrypi/src/ReSpeaker%202-Mics%20Pi%20HAT_SCH.pdf

Best regards,
Walker

Ahh, I feared that this was the case. If it's not on the board, then it
shouldn't be in the dts (and certainly nothing should be in
jh7110.dtsi!).
I suppose this should be a dt-overlay, but I don't know anything about
the upstream infrastructure for those. Nor do I know what is permitted
in terms of overlays.

Thanks,
Conor.
