This series add H6 I2S support and the I2S node missing to support HDMI audio in different Allwinner SoC.

Applied to

https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git for-next

Yay!

Note that this doesn't bring HDMI audio card just yet. Another driver will be needed for that.

Now, I wonder: will that make it easier to add support for HDMI-Audio for the A10/A20?

No, A10/A20 HDMI audio uses completely different interface.

(there was a patch for that submitted earlier this year by Stefan Mavrodiev stefan@olimex.com, but it seems there hasn't been any progress on it since then (I think the last message on it concluded that it should be rewritten to use ALSA instead of ASoC)).

IIUC original author left Olimex, so work stalled.

Best regards, Jernej

[ To clarify, don't know what's the difference between ALSA and ASoC; I'm only interested here as an owner of an A20 box on which I'd love to be able to use the HDMI-Audio. ]
