[PATCH v2 0/7] Add missing peripherals to Allwinner V3s/V3 device trees

[PATCH v2 0/7] Add missing peripherals to Allwinner V3s/V3 device trees

[Tobias Schramm]

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 v2 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

[PATCH v2 3/7] ARM: dts: sun8i: v3s: add analog codec and frontend to v3s dts

[Tobias Schramm]

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.

My bot found errors running 'make DT_CHECKER_FLAGS=-m dt_binding_check'
on your patch (DT_CHECKER_FLAGS is new in v5.13):

yamllint warnings/errors:
./Documentation/devicetree/bindings/sound/allwinner,sun8i-a23-codec-analog.yaml:21:9: [warning] wrong indentation: expected 10 but found 8 (indentation)

dtschema/dtc warnings/errors:

See https://patchwork.ozlabs.org/patch/1478254

This check can fail if there are any dependencies. The base for a patch
series is generally the most recent rc1.

If you already ran 'make dt_binding_check' and didn't see the above
error(s), then make sure 'yamllint' is installed and dt-schema is up to
date:

pip3 install dtschema --upgrade

Please check and re-submit.
