[alsa-devel] ASoC SSP Driver Question
Hi,
I'm working on ASoC driver for TI WL1273 (BT/FM) using the Bulverde SSP from IPGEAR peripheral. I have seen that a pxa_ssp driver already exists however I'm not if we have to use it as is it and adapt our SSP PCI driver to Interface with the pxa-ssp, or can we propose an "intel_ssp" ASoC driver?
Thanks,
Selma.

You can do any of those things that make sense. Please make sure that you coordinate your work with the other work going on on Intel platforms - there's some drivers been submitted recently for the MIDs, and there's more work coming on those.

Are you using the the existing ASoC codec driver for WL1273? It is in the tree: sound/soc/codecs/wl1273.*
I have put Matti Aaltonen, the author of the codec driver to the CC list.

Yes, I'm planning to use this codec driver however I'm not sure that it supports the FM capture. According to the code, the codec handles the WL1273_MODE_BT mode only. The ASoC driver I'm working on handles both BT and FM.

The BT mode is the default, but the driver supports both FM TX and RX as well. The change can be done via the "Codec Mode" ALSA control.
The driver in upstream supports the shared I2S lines only (shared between BT/FM radio). The codec has dedicated FM I2S lines, but in the HW we have it is not connected, but IMHO it can be easily added as another DAI on the codec.
