Hi,

Morimoto-san pointed out in a private thread that the davinci-i2s driver is
using snd_soc_rtdcom_lookup(), which is should not really.

It took a while to get access to a daVinci board which uses McBSP, but
eventually I got access to a remote dm644x-evm and dma365-evm.

Initially the audio was not even probing on them (fixes sent for mach-davinci),
but then the driver was still crashing and not behaving correctly.

With the 4 patch dm644x-evm have working audio and the offending
snd_soc_rtdcom_lookup() is gone from the driver.
dm365-evm still have some issues regarding to EDMA, but it looks like a system
issue which can be fixed later.

Regards,
Peter
