[PATCH v3 0/7] ASoC: add Allwinner H616 audio codec support

[Ryan Walklin <ryan@xxxxxxxxxxxxx>]

Hi All,

V3 of this patch adding support for the Allwinner H616 (and variant)'s audio codec. Some clarification of comments, particularly regarding the clock driver changes, and a small fix for the device tree binding (apologies I forgot to re-run dt_binding_check on V2). Review comments otherwise addressed and reviews noted.

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).

Changelog v2..v3:
- Update clock driver patch commit message and inline comments to more accurately describe SDM changes.
- Fix missing "-" in H616 conditional binding as reported by dt_binding_check
- Add additional clarification of internal playback_only quirk in sun4i-codec driver
- Add short driver_name to H616 codec driver and restore descriptive name.
- Remove leading 0 from codec node's address in H616 device tree to match other blocks.

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
