[PATCH v2 00/10] allwinner: a523: Enable I2S and SPDIF TX

[Chen-Yu Tsai <wens@kernel.org>]

Hi folks,

This is v2 of my Allwinner A523 family I2S and SPDIF enablement series.

Changes since v1:
- Collected tags
- Dropped clk patches that were merged
- Added patch for SPDIF pinmux settings that was missing in v1
- Dropped bogus change to DAI name in SPDIF driver
- Dropped clk rate message in SPDIF driver
- Switched my email to kernel.org one

This series enables the SPDIF and I2S hardware found on the Allwinner
A523/A527/T527 family SoCs. These SoCs have one SPDIF interface and
four I2S interfaces. All of them are capable of both playback and
capture, however the SPDIF driver only supports playback.

The series is organized by subsystem, so each maintainer can find the
patches they need to take.

Patch 1 adds SoC/hardware specific compatibles for the two DMA
controllers in the A523 SoC.

Patch 2 adds an SoC specific compatible for the I2S interface
controllers in the A523 SoC.

Patch 3 adds an SoC specific compatible for the SPDIF interface
controller in the A523 SoC.

Patch 4 adds driver support for the SPDIF interface.

Patch 5 adds devices nodes for the DMA controllers.

Patch 6 adds a devices node for the SPDIF interface controller.

Patch 7 adds device nodes for the I2S interface controllers.

Patch 8 adds one set of pinmux settings for I2S2.

Patch 9 adds pinmux settings for SPDIF.

Patch 10 is what I used to test the changes, and serves as an example
for how to use these new interfaces.


Patch 1 can go through the dmaengine tree, or I can take it through the
sunxi tree.

Patches 2 through 4 should go through the ASoC tree.

The rest, except the example, will go through the sunxi tree.


Please take a look.


Thanks
ChenYu
