Hi Jon, from what I've seen from the code it looks like Allwinner cripples the functionality of the controllers by hardcoding whether the block is used as to connect to a I2S device or a PCM device. I've not seen anything reference I2S2. With HDMI audio driver I noticed that it referenced the I2S block but after stripping everything I2S related out of it; it still seemed to work. If you're looking at mainlining work..I would develop a seperate sunxi_i2s and a sunxi_pcm and then assign them using the device tree. BR, CK
