Hello everyone,

This is a first version of a serie to add ADC support
for Sun8i-A33.
Based on asoc/for-next branch, last commit:
20d5c84bef067b7e804a163e2abca16c47125bad.

The first patch adds the support of ADC and microphones in the digital
part (driver sun8i-codec).
The second one adds the route between analog (sun8i-codec-analog) and
digital (sun8i-codec) parts to have a functional ADC route on Sun8i-A33
device tree.

Tested on Allwinner R16 Parrot board with microphone 1 (external) and
microphone 2 (headset).

I forgot to add in my cover-letter amixer commands used to test it:

amixer set 'AIF1 Data Digital ADC' cap
amixer set 'Mic1' cap
or
amixer set 'Mic2' cap

and, just in case, the commands to enable output/DAC:

amixer set 'Headphone' 50%
amixer set 'Headphone' on
amixer set 'DAC' on
amixer set 'AIF1 Slot 0 Digital DAC' on

I am not sure about the bias handling so if you have any comments on it,
do not hesitate.

Thank you in advance!
