Hi,   OPiPC with latest mainline (ARMBIAN 5.34 user-built Ubuntu 16.04.3 LTS 4.13.12-sunxi). Need to test the I2S0. From what I see in patches, the I2S driver code is already there so I just need an overlay to use it.   Is there any DT overlay for using the H3 I2S0 with any codec ? Even as a generic simple-audio-codec ?   Christos
