The I2S block used for the audio codec in the A64 differs from other 3 I2S modules in A64 and isn't compatible with H3. But it is very similar to what is found in A10(sun4i). However, its TX FIFO is located at a different address.

This compatible is already used as the SoC-specific compatible (in case we have unforeseen differences between A64 and H3 I2S).
Since this is tied to the codec, I think it deserves a special compatible anyway. How about "allwinner,sun50i-a64-codec-i2s" ?
The rest looks good, so once the compatible is changed,
