I have tested and found that sai<->aif1 can support "i2s" "left_j" "dsp_a" "dsp_b" format, and can support cpu dai master and slave mode. But I haven't tested voice dai and bt dai because of hardware limitation. I just using sai<->aif2 to test aif2. So I want to configure the dai format from device tree. And there is a help function snd_soc_of_parse_daifmt for me to do this, so I add these selectable to the machine driver. > > > + model = "wm8960-audio"; > > Cut'n'paste error here. it should be "wm8958-audio", i will modify it.
