The Allwinner V3s/V3 SoCs feature quite a few peripherals that have good
driver support but yet are nowhere to be found in the SoCs dts.
This patchset adds the DMA controller, the relevant DMA properties for all
peripherals supporting DMA, the integrated analog codec and - for the
Allwinner V3 SoC - also the I2S interface.
I've included all of those changes in one patchset since they do all
depend on addition of the DMA controller.
All changes have been tested in a recent project of mine using a Sochip S3
(a rebranded Allwinner V3) and are confirmed working.
This is v3 of this patchset.
Cheers,
Tobias
Changelog:
v2:
- add v3/v3s specific compatible strings
- fix v3s audio codec analog frontend compatible
- fix an I2S -> I2C typo
v3:
- fix yaml list indentation in allwinner,sun8i-a23-codec-analog.yaml

2.31.1
The Allwinner V3s and V3 SoCs feature an integrated analog audio codec.
Additionally both have an analog frontend with mixers and amplifiers for
the codec.
This commit adds both, the analog codec and its frontend to the V3s dtsi.

2.31.1
The Allwinner V3 SoC has a different analog codec frontend than the V3s
SoC. The frontend used on the V3 SoC is compatible with the on used in
the Allwinner H3 SoC.
This patch adds the corresponding node to the Allwinner V3 dtsi.

2.31.1
The analog codec frontend of the Allwinner V3 is compatible with the
analog codec frontend used on the Allwinner H3.
This patch adds a compatible string for the analog codec frontend on the
Allwinner V3 SoC.
