Hi,

V2 of this patch adding support for the Allwinner H616 (and variants) audio codec. Some rework to improve clock correctness, and DTS changes to enable the codec on boards added.

Changelog v1..v2:
- Reordered patches to group ASoC changes
- Corrected PLL_AUDIO clock dividers to match values from manual and vendor SDK.
- Remove PLL_AUDIO_4X clock from the device tree binding (not used in the driver).
- Restrict TX-only DMA changes to the H616.
- Change the codec name to fit into the 16 char limit.
- Move the codec (and spdif) blocks in the H616 DTSI to restore address-order.
- Add board enablement (and power/GPIO changes for RG35XX to support speaker amp).


Original blurb below:

Hi,

The Allwinner H616 has a playback-only audio codec, with a single stereo or differential-mono line output.

This patch adds support for the H616 (and H313/H618/H700/T507) SoC. Based on the  Allwinner kernel SDK driver, and tested on the H700.

Regards,

Ryan
