The probe was tested but I am still fighting to get audio out. There are 
additional patches needed to work-around a BIOS changes that fixes the 
download issue shown in your log and also a change in the I2S routing, 
but we can't figure out if there are any additional changes needed. I 
suspect something is wrong with the i2S pin configuration (gpio setup)
Those patches and updated firmware have not been submitted so far, i'd 
like to do so when it's actually working. This is on our to-do list, 
along with MCLK support and jack detection. There are so many variations 
of hardware that we are progressing slowly unfortunately.
