Commit Message

The H616 has an audio codec compatible with the sun4i-a10 driver.

The codec is relatively cut down compared to some of the other Allwinner
SoCs and only has a single line-out route (relying on a separate digital
microphone IP block for input). HDMI and SPDIF audio are handled
separately by an audio hub IP block, which is not currently implemented
in mainline kernels. This requires some additional flexibility in the
DMA bindings.

Add compatible string and routing for the H616 audio codec, and update
the required DMA descriptions.

Changelog v1..v2:
- Remove PLL_AUDIO_4X clock from definition (defined internally but
  not used by driver and so not required in DTSI)
- Restrict TX-only DMA definition to H616

Changelog v2..v3:

- Fix missing - in H616 conditional binding reported by dt_binding_check.

Are you keeping preferred ordering of entries? Usually it is
alphanumerical, but you introduce now by model number.

Please submit patches using subject lines reflecting the style for the
subsystem, this makes it easier for people to identify relevant patches.
Look at what existing commits in the area you're changing are doing and
make sure your subject lines visually resemble what they're doing.
There's no need to resubmit to fix this alone.
