[PATCH v2 00/12] Add support for the audio codec on Allwinner V3s

[Icenowy Zheng]

Allwinner V3s features a audio codec with dedicated digital and analog parts,
like the ones on A23/H3, but much simpler (lack of MIC2, LINE IN and MBIAS).

Add support for it.

In order to make the codec usable, DMA support is also added in this series;
the support of Lichee Pi Zero's dock board is also added here, as it's the
only board hackable that come with ports connected to the codec.

Patch 1~3 split out parts that is not available on V3s in the analog codec.

Patch 4/5 adds support for V3s in analog/digital codec.

Patch 6 add the gate bit as a common quirk of sun6i-dma driver, as V3s also
needs it.

Patch 7 really adds support for V3s in DMA engine.

Patch 8 restores the inclusion of CCU headers in the DTSI file of V3s, as
it's removed when merging.

Patch 9/10/11 adds three parts of V3s: DMA engine, codec support and pinmux
of mmc1 (used on Lichee Pi Zero dock).

Patch 12 adds support for Lichee Pi Zero dock, with support of mmc1 and
codec.
