Hi everyone,

This is v3 of my Allwinner A31 audio codec support series. These are
the remaining driver patches not yet merged, with 1 new fix, and the
dts file patches.

The A31's internal codec is similar (in terms of DMA, interface and
control layouts) to the one found in the A10/A13/A20 SoCs. However
it has more external inputs and outputs, the mixer controls are now
stereo (left/right separated), and it also has some audio processing
features (not supported yet).

Changes since v2:

  - Added patch """ASoC: sun4i-codec: Add "Right Mixer" to "Line Out
    Mono Diff." route""" which fixes line out when all the sources
    have their left channel muted.

  - Dropped unused codec_pa_pin from A31 hummingbird dts patch.
    In the past we always provided a pinmux setting for GPIOs used, to
    avoid accidentally muxing a pin that was already used for GPIO, or
    vice versa. The pinctrl subsystem now supports exclusive use of a
    pin for GPIO, which the sunxi platform wants to migrate to. This
    drops the requirement of the explicit pinmux setting for GPIOs.

  - Added Maxime's Acked-by for the two existing patches from v2.

After these are merged I plan to submit patches to support the audio
codec found in Allwinner's A23 and H3 SoCs.

Regards
ChenYu
