Hi,
This is some work done by Marcus Cooper and Jernej Škrabec. These patches are present in LibreElec kernel and have been tested by LE users.
I have rework them to follow kernel rules but I can't test them as I don't have H3, H5 or A64 boards.
If some sunxi users could confirm they worked as expected!
This serie goes in top off "Add H6 I2S support"[0]. You can find a branch for testing here[1].
Thanks, Clement
