Subject: [PATCH v2 0/5] Allwinner H6 SPDIF support

*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.

Clément Péron (5):
  dt-bindings: sound: sun4i-spdif: Add Allwinner H6 compatible
  ASoC: sun4i-spdif: Add support for H6 SoC
  arm64: dts: allwinner: Add SPDIF node for Allwinner H6
  arm64: dts: allwinner: h6: Enable SPDIF for Beelink GS1
  arm64: defconfig: Enable Sun4i SPDIF module
