Hi,
I was trying to get audio on the F1C200s, but so far had no luck, and I
came across this series.

This is RFC patchset for Allwinner suniv F1C100s to support DMA and
audio codec.
Allwinner F1C100s has a audio codec that has necessary digital and
analog parts. It has r-l headphone output and microphone, line, r-l
FM inputs. ADC can capture any inputs and also output channels via mux.
Any input channels or DAC samples can feed output channels.
Add support for this audio codec.
F1C100s utilizes DMA channels to send and receive ADC-DAC samples. So
DMA support needed. Patch 1~5 adds support for DMA. Suniv F1C100s has
very similar DMA to sun4i. But there is some dissimilarities also.
Suniv features a DMA reset bit in clock control unit. It has smaller
number of DMA channels. Several registers has different addresses.
It's max burst size is 4 instead of 8. Also DMA endpoint numbers are
different.
Patch 6 adds DMA max burst option to sun4i-codec.
Patch 7~8 Add support for suniv F1C100s audio codec.
Patch 9 adds audio codec to suniv-f1c100s.dtsi
Patch 10 adds audio codec support to Lichee Pi Nano board.
Thanks!

What's the status of this series? I see that it was not merged, despite
getting a few ACKs and only a few minor comments. Ripard's comments make
me believe that the sun4i DMA driver should be able to handle the suniv
family with minimal adjustments, have those not been added? Or is it
that the DMA support is ready but the ALSA/ASoC support is missing?
