[alsa-devel] [PATCH v4 0/7] Allwinner H6 SPDIF support

[Clément Péron]

*H6 DMA support IS REQUIRED*

Allwinner H6 SoC has a SPDIF controller called One Wire Audio (OWA) which
is different from the previous H3 generation and not compatible.

Difference are an increase of fifo sizes, some memory mapping are different
and there is now the possibility to output the master clock on a pin.

Actually all these features are unused and only a bit for flushing the TX
fifo is required.

Also this series requires the DMA working on H6, a first version has been
submitted by Jernej Škrabec[1] but has not been accepted yet.
