[alsa-devel] [PATCH 02/10] ASoC: sunxi: Add support for A23/A33/H3 codec's analog path controls

[Icenowy Zheng]

12.11.2016, 14:57, "Chen-Yu Tsai" <wens at csie.org>:
> The internal codec on A23/A33/H3 is split into 2 parts. The
> analog path controls are routed through an embedded custom register
> bus accessed through the PRCM block.
>
> The SoCs share a common set of inputs, outputs, and audio paths.
> The following table lists the differences.
>
>     ----------------------------------------
>     | Feature \ SoC | A23 | A33 | H3 |
>     ----------------------------------------
>     | Headphone | v | v | |
>     ----------------------------------------
>     | Line Out | | | v |
>     ----------------------------------------
>     | Phone In/Out | v | v | |
>     ----------------------------------------
>
> Add an ASoC component driver for it. This should be tied to the codec
> audio card as an auxiliary device. This patch adds the commont paths
> and controls, and variant specific headphone out and line out.

sun50i-a64 has a similar (or the same?) codec to A33.
