Hi.
The attached patch adds a dummy codec for the asoc subsystem. I use it with the driver that programs the soc to drive I2S from an internal PLLs, and the audio then goes to HDMI, so no external codec is used. I've found spdif_transciever.c, which exactly is such a dummy driver, but it is bound to the particular plat device, so I made the device name a config option, and if not set, the plat device is created with the default name.
It may be possible to avoid the usage of the codec driver at all, but I haven't succeeded with this, and the existance of spdif_transciever.c suggests there is no such way. Thoughts?

Hi,
There is already a dummy codec driver.
Please take a look at sound/soc/soc-utils.c

Lars, indeed, this codec is present in a git kernel and it wasn't in mine android kernel. But, that driver is too dummy to even work at all.
The attached patch adds a playback stream for the dummy codec. Would it be possible to apply this?
Looks fine to me, although it might make sense to also add a dummy capture stream. But you need to send the patch to Mark and Liam who are the ASoC maintainers. Also use the proper subsystem prefix, which is "ASoC" not "asoc", add a patch description, sign off on the patch itself and try to send it inline instead of an attachment.
