Hi,
This is the series adding support for internal audio codec on Allwinner D1/T113s SoCs family.
My work based on Icenowy Zheng's patches from sipeed repo that adds support for the R329 audio codec. But, unfortunately, these patches were not sent to upstream. So, I adapted them to fit the T113s. In the future, support for R329 could easily be added on top of this series. Because D1/T113s and R329 SoCs have almost the same audio codec IP, with slight differences in the analog part, plus the R329 has two additional ADCs.
The series includes modifications for the existing sun4i-codec driver that brings support for the digital part of the D1 codec. And adds the new sun20i-d1-codec-analog driver for the analog part.
I would be glad if someone have a look :)
Cheers, Maksim
