This really looks wrong. Excuse me for not following here, but Walker, could you point me at where in the schematic for the VisionFive 2 that this wm8960 actually is? I know ~nothing about audio, but good old Google tells me that this is a dedicated codec chip and I was looking at [1] and could not easily find it on the schematic. Thanks, Conor. 1 https://doc-en.rvspace.org/VisionFive2/PDF/SCH_RV002_V1.2A_20221216.pdf

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

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.

Why card0? There are several audio interfaces in JH7110 SoC, each as an independent sound card. TDM is for snd-card0, latter i2s will be for snd-card1, spdif will be for snd-card2, etc. > 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. It seems that the sound node should be located in DTS file more appropriately. Best regards, Walker
