I want to develop an audio board for the Raspberry Pi 2, based on the ad1938 audio codec.
Moreover I want to simultaneously capture and playback audio streams, so I have to use the TDM (TIME-DIVISION MULTIPLEXED) mode.
Do anybody know if it's possible to use this TDM mode on the Raspberry Pi 2, especially the BCM2836?
I've already seen an ASoC platform driver for a Blackfin SoC, called "bf5xx-tdm".
So, I think, if the Raspberry Pi 2 would already support the TDM mode, there would be also a platform driver called "bcm2708-tdm", correct? (So, I think I have to develop a platform driver on my own.)
Can anybody help me or has some good resources for this subject?
Thank you very much!
