[alsa-devel] [PATCH 0/1] ASoC: TWL4030: Digital loopback support

Hello,

The following patch adds the digital loopback support for TWL4030 codec driver.

Effectively the digital loopback is routing the audio from the TX1 capture path to the RX2 playback path.

With the patch applied, the audio coming from digimic0 can be routed back to the playback path without any CPU interaction. Also one can use this loopback instead of the analog bypass for the analog inputs as well, given that the TX1 capture path is configured in such a way.
