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 Tobias Schramm (7): ARM: dts: sun8i: v3s: add DMA controller to v3s dts ARM: dts: sun8i: v3s: add DMA properties to peripherals supporting DMA ARM: dts: sun8i: v3s: add analog codec and frontend to v3s dts ASoC: dt-bindings: sun8i-a23-codec-analog: add compatible for Allwinner V3 ARM: dts: sun8i: V3: add codec analog frontend to V3 dts dt-bindings: sound: sun4i-i2s: add Allwinner V3 I2S compatible ARM: dts: sun8i: V3: add I2S interface to V3 dts .../sound/allwinner,sun4i-a10-i2s.yaml | 3 ++ .../allwinner,sun8i-a23-codec-analog.yaml | 9 +++-- arch/arm/boot/dts/sun8i-v3.dtsi | 31 +++++++++++++++ arch/arm/boot/dts/sun8i-v3s.dtsi | 39 +++++++++++++++++++ 4 files changed, 79 insertions(+), 3 deletions(-)
