*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.
Also this series require the DMA working on H6, a first version has been submitted by Jernej Škrabec but is not yet accepted (as this moment): https://patchwork.kernel.org/project/linux-arm-kernel/list/?series=89011
This series has been tested on Beelink GS1 on top of sunxi/for-next with Jernej DMA support patch.
