The peripheral type specified in the dma phandle for each SAI node
is incorrect. Change it to specify the SAI peripheral.

Hi Matt,
Why do you think this is incorrect? AFAIK script number 2 works fine
for SAI. Can you add
more details on what bug are you encountering?
Adding Robin the owner of SDMA.

Hi Daniel,
Thanks for the response. I was experiencing timeouts that were traced
back to dma incompletions. Changing the script at the time fixed that
issue. Now, given your response I went back and checked this again and
verified that script 2 does work for me now. I did change firmware to
the latest v4.4 from something quite old so now I'm suspecting I had
bad firmware loaded up. Does that sound plausible? In any case, I can
confirm this is not needed.

No, that's not related with firmware version since both scripts are all ROM scripts instead of RAM scripts which's in sdma firmware.
