Subject: [PATCH 0/2] Apple ADMAC driver
Date: Wed, 30 Mar 2022 18:44:56 +0200 [thread overview]
Message-ID: <20220330164458.93055-1-povik+lin@cutebit.org> (raw)
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.
Martin
