I'd keep it sun50i_a64_acodec_i2s, since other 3 I2S modules aren't compatible with this one, but similar to H3.
Well I wouldn't and the description of it is usage is clearly stated in the devicetree for the dai.
OK, how would you name 3 other I2S modules that are present in A64?

The I2S block used for the audio codec in the A64 is very similar to what is used by the A10(sun4i) devices. However, its TX FIFO is located at a different address.
[vasilykh: - added fixed_wss and wss_value to A64 quirks, - changed compatible to 'allwinner,sun50i-a64-acodec-i2s, since A64 has 3 more I2S blocks that are not compatible with audio codec I2S]
This needs to be investigated more...I'm suspicious of the SUN8I_I2S_FMT0_LRCK_PERIOD value which is hardcoded to 0x1f. I've made this following change https://github.com/codekipper/linux-sunxi/commit/4c5fe5f5576cfbb2e1e94a99cd1... which seems to work for me but I would like to look at it with a logic
I tried this change and now it works fine for me as well without hardcoded WSS value. So problem was in hardcoded LRCK period. Are you OK with me submitting this patch as a part of my A64 audio series?
analyser and test other sample depths. CK
I'm afraid it's not possible to get inside of SoC, since internal I2S pins do not go out. And other 3 I2S modules are different from one for internal codec.
I just think this needs more of an investigation, I've git a similar patch https://github.com/codekipper/linux-sunxi/commit/282d986b6f9ed441ecdc996c6dc... which I've not delivered for that very reason. CK
