[alsa-devel] [RFC][ASoC] New device/driver arch

Hi Liam,

Is it possible to have 2 physical I2S units (which are connected to the same
codec) be repesented as a single ASoC device? (The SH7760 has 2 I2S units
which are "halfduplex" (only transmit OR capture at a time). My dev platform
simply uses the second unit for capture

I need a trigger callback in the  machine driver to properly support
multichannel I2S audio on Au1200 (the  Au1200 can only do stereo; to get
more channels we double/quadruple the I2S LRCLK coming from the codec;
however the CPLD needs to be told when a new sample starts; although
maybe that can be worked around in VHDL)

Thanks for the great work
	Manuel Lauss
