Hi,
for your review I am submitting a driver for Audio DMA Controller on
recent Apple SoCs.
One note I want to leave: The docs appear to be wrong on the residue
semantics of device_tx_status. They say "In the case of a cyclic
transfer, it should only take into account the current period."
But e.g. ALSA expects the residue to be of the full buffer.
